General Functionality
Items in the “General Functionality” category are independent of any particular
GibbsCAM package or function.
•
Changes in installation and system considerations are discussed in System and Installation
Changes.
•
Changes affecting the GibbsCAM interface are discussed in “Interface Changes” on page 14.
•
Functional changes that apply to many or all products are discussed in “Functional Changes”
on page 18.
System and Installation Changes
Items discussed below are independent of any particular GibbsCAM package or function.
Update Notifier
When GibbsCAM 2011 first starts, it checks for updated releases (if an Internet connection is
available). If a later version of GibbsCAM is available, a message dialog appears:
•
If you are current on Maintenance, the message prompts you to visit a web page where you
can see information about the update and decide whether to download and install it. The
update system will never automatically install any software.
•
Otherwise, the message tells you that Maintenance is required if you want the latest version.
Notes on Update Notifier
•
Help menu option Check for Updates performs a one-time update check.
•
If you do not want GibbsCAM to check for updates each time it starts, go to File >
Preferences , Interface tab, and clear the checkbox Automatically Check for Updates on Startup.
Installation
New Installation Media
To accommodate separate 32-bit and 64-bit installations for each language, GibbsCAM software
is now delivered on multiple dual-layer DVDs. The same installer is used to install from physical
11
media or from the website.
New Installation Capabilities
The GibbsCAM installation process now automatically detects the default national language and
whether the platform is 32-bit or 64-bit. It has been redesigned to make greater use of the
Microsoft Windows Installer (MSI) in the following ways:
•
You can now selectively install or uninstall individual product options and components.
•
You can easily repair an incomplete or damaged installation, such as when a file is
accidentally moved, deleted, or overwritten.
•
Optionally, you can associate GibbsCAM with the context menu (right-click menu) of
filetypes other than .vnc, including .sat, .sab, .asat, .asab, .dlv, .model, .dxf, .igs,
.catpart, .catproduct, .x_t, .xmt, .par, .vda, .3dm, .prt, .stl, .iam, .ipt, .ckd,
.asmsldpart, .sldasm, .x_b, .p_b, .dwg, .step, and .stp.
•
When installing from the command line, standard msiexec options can be used, such as /q
(quiet) options to install with little or no user interaction and /l (logging) options to record
status and warning messages, parameters, and so forth.
Note: In accordance with Microsoft guidelines for Vista and Windows 7, the GibbsCAM
shortcut is created as public desktop item that does not support drag-and-drop of *.vnc or
other files onto it. To create an old-style desktop icon that supports drag-and-drop application
launching, navigate to the Bin\ subfolder of the installation directory, select Virtual.exe, and
CTRL+ALT-drag it to you desktop, creating a new shortcut.
New Folder/File Organization
The disk layout of GibbsCAM files has been standardized; for example, binary executables are
separated from resource files, and the location of machine-specific files, including MDDs and
VMMs, has changed. For details, refer to the Installation guide.
Migrating Settings and Preferences
The GibbsCAM Migration Tool lets you detect all previously installed versions of GibbsCAM and
copy compatible settings and preferences — display settings, custom MDDs and VMMs, bolt
and tap table data, macro configuration file, machine models, and so forth — from a specified
previous version to the current release. The previous version is not modified.
For best results, run the Migration Tool before the first time you start a newly installed release
of GibbsCAM. This allows old files to be migrated before they are blocked by new files created
in the newly installed version.
Using the GibbsCAM Migration Tool
You can launch the tool from the Start menu: GibbsCAM > Migration Tool v10.
12
1.
The first dialog lets you scan your system for installed versions of GibbsCAM, select one
from the list, and check it for compatibility.
2. The second dialog shows you the files that can and cannot be copied forward to the current
release. Appropriate restrictions are respected if Administrator privileges are lacking.
Note: There is no ability to migrate plug-ins or material databases from previous releases.
However, settings for Plug-In Manager can be migrated.
64-Bit Integration
GibbsCAM 2011 is fully compatible with both 64-bit and 32-bit Windows. The ability of 64-bit
systems to handle more RAM and use larger chunks of information gives them a performance
13
advantage if your part files are mid-size or larger or if you run many tasks simultaneously. The
GibbsCAM installer detects which platform you have and installs the corresponding version of
the software.
GibbsCAM macros and Reporter functions are fully compatible with Microsoft Excel in both 32bit and 64-bit modes.
All plug-ins distributed with the product are 64-bit compatible. However, we cannot guarantee
third-party plug-ins. If you have a 32-bit-only plug-in, please contact your third-party plug-in
vendor.
Please note that 32-bit VMMs cannot be used on 64-bit GibbsCAM. If you need a 64-bit VMM,
please contact the Post department ([email protected]). Customers on Maintenance can
upgrade their 32-bit VMMs to 64-bit at no charge.
Interface Changes
Items discussed below are common to all GibbsCAM product options.
Menus, Behaviors, and Look-and-Feel
New main menu Features replaces Wizards. New menu items under Features include Attribute
Manager and Feature Manager (see “Attributes and User-Defined Features” on page 18).
Changes to Plug-Ins
Menu item Stock Wizard is now under Plug-Ins > Misc.
Plug-In Manager, available under the Plug-Ins menu, lets you globally activate/deactivate
individual plug-ins and plug-in groups.
Important: Deactivating a plug-in disables that plug-in's function throughout GibbsCAM. For
example:
•
If the EDM plug-in (EdmPlugin.dll) is deactivated, then Wire EDM does not appear on the
main menu.
•
If the Transform Toolpath plug-in (TpTrans.dll) is deactivated, it does not appear on the list
of available Operation Modifiers.
•
If the Read SolidEdge Assembly plug-in (ReadSEAsm.dll) is deactivated, the SolidEdge
Assembly (*ASM) choice does not appear among the file types offered in the Open part file or
Import file dialogs.
Plug-In Manager also gives you control over menu items and sub-items displayed in the Plug-Ins
menu. You can right-click to add and rename folders and subfolders, and you can move
items or entire groups using drag-and-drop. The menu does not display empty folders. Folder
names cannot contain the characters (<^/\;!.
Changes that are made by Plug-In Manager take effect the next time GibbsCAM is started.
14
Other new plug-ins include Touch Interface Manager and Update Notifier; see below and
“Update Notifier” on page 11.
Changes to Task Bar, Context Menus, Tiles, and Tile Lists
The task bar has a new button that allows you to choose color display mode:
See “Color Modes” on page 17.
Context menus (right-click menus) contain new options for manipulating user color. And when
Profiler is active, the context menu now includes an Extract Selected Profile option.
Context menus for the Tool List and Process List now offer a Tool Manager and a Process
Manager, similar to the Operation Manager.
All three managers allow you to edit data fields. Warning: You cannot undo the results of
editing a tool, process, or operation.
You can now shorten or extend tile lists by dragging the divider between the Tool List and
Process List or by dragging the lower edge of the Process List or Operation List.
You can now undo the results of a sorting an operation list or tool list.
Geometry Creation
When creating geometry, you can now create rectangles by specifying X and Y distances from
edges or corners, and you can now offset shapes using square corners.
15
Freehand Move and Rotate
You can now move or rotate elements using the mouse: Select one or more elements, press
Ctrl+Alt to pop up a temporary axis block, and then drag either the origin (for freehand
translation) or one of the six axes (for axis-constrained translation or rotation).
Touch Interface
With suitable hardware, on Windows 7, you can now use touch gestures to control common
viewing actions, such as move/rotate, zoom, and restore. To enable or disable controls, use
Plug-Ins → Misc → Touch Interface Manager .
16
For information on general interface items, refer to the Getting Started guide.
Color Modes
You can now choose amongst color modes for displaying workspace items:
•
Gibbs Colors mode is always available. In this mode, workspace display is governed by the
Colors tab of the Appearance Settings dialog.
•
Feature Color mode is available if the part contains user-defined features. In this mode, items
in the workspace are displayed according to their feature color assignments defined in
Feature Manager.
•
User Color mode is available if any element in the part is tagged with the reserved attribute
named User Color. In this mode, workspace display is governed by the palette of colors
defined in the Attribute Manager dialog for the User Color attribute.
•
Other user-created color modes are available if elements are tagged with other user
attributes of type color. Workspace display is governed by the palette of colors defined for
the corresponding user-created color attribute.
For more information on color modes, refer to the Features guide.
17
Functional Changes
Items discussed below are common to all GibbsCAM product options.
•
Attributes and User-Defined Features below

“Holes and Hole Features” on page 20
•
“Operation Modifiers” on page 23
•
“Managers for Tools, Processes, and Operations” on page 24
Attributes and User-Defined Features
The Attribute Manager dialog, accessed from the Features menu, lets you view, create, and
manage user-defined attributes:
In addition, you can now preserve CAD attributes in models you import into GibbsCAM:
18
About Attributes
Attributes provide a way to associate data values with elements or to tag elements as belonging
to a user-defined Feature.
•
A data attribute consists of a name, a data type (integer number, real number, text, or
color), and a default data value. A Feature attribute consists of a name and a color. Color
includes both RGB hue and transparency.
•
A single element, such as a piece of wireframe geometry, a face, or an entire solid body, can
be tagged with many attributes. A single attribute can be attached to many different
elements.
•
You use Attribute Manager to identify, select, filter, sort, and otherwise manipulate
elements that are tagged with a particular attribute (or even multiple attributes). For
example, you could find all elements tagged with a MyNomOD attribute and select only those
whose MyNomOD value is 1.5.
•
Attributes of data type color, including the reserved attribute named User Color, have their
names appear on the list of color modes. For example, you could define a color named
Revision, assign a value of transparent black to all existing elements, and then assign colors
to changed elements according to their revision status. The new Revision color mode would
then allow you to visualize and select elements in a new way.
For details on attributes and Attribute Manager, refer to the Features guide.
User-Defined Features
The Feature Manager dialog, accessed from the Features menu, lets you view, create, and manage
user-defined features:
19
The Feature attribute type allows you to collect elements and designate the collection with a
name and color. For example, you could tag the faces of a slot with a blue Feature attribute you
call MySlotBlue. Then, Feature Color mode would provide a quick way to distinguish all userdefined features, and Feature Manager would let you easily select the elements tagged as
MySlotBlue for machining.
For details on user-defined features and Feature Manager, refer to the Features guide.
Holes and Hole Features
The Drill tab of the Holes Process has new controls — custom drill cycles (when the necessary
support files are installed; see Custom Drill Cycles, below) and the Reverse Order check box —
described in “Production Mill, Lathe, and Mill/Turn” on page 26.
Hole features in SolidWorks models are preserved and recognized when imported into
GibbsCAM.
New options make it easier to select a Hole feature, whether predefined or to be defined
through Automatic Feature Recognition (AFR). Hole Manager lets you select holes according to
CS the hole is aligned with, or one or more individual faces that constitute the hole, and the
context menu when a face is selected provides Select Adjacent Holes.
20
Hole Manager and Hole Wizard
Hole Manager, now accessed from the Features menu, now includes an Auto Wizard that
streamlines and automates hole creation. If you set Preferences to minimize user intervention,
the power of Hole Wizard is greatly increased: You can automatically recognize, group, and drill
thousands of holes in just three button clicks: Run AFR, Auto Group, and then Auto Wiz.
Hole Manager context menus have been expanded with new options, many of which are
available even when multiple rows are selected.
You are now able to copy and paste holes from one workgroup to another.
21
The Lock Selection checkbox highlights holes when rows are selected and highlights rows when
holes are selected, providing immediate visualization of workspace and Hole Manager selection
sets.
For details on the new Hole Manager capabilities, refer to the Features guide, which was
formerly named the Wizards Guide.
Custom Drill Cycles
Custom drill cycle macros can be called from the Drill tab of the Holes process and from the 5Axis Drilling Options tab. A sample set of macros is available to illustrate custom drill cycles for
Variable Peck.
These macros, along with the custom MDDs to support them, can be downloaded from the
Macros wiki (https://macros.GibbsCAM.com). For example, in the web page for the category
Custom_Drill_Cycles, you can download the following items.
•
Example macros for: Variable-peck drilling by Distance or Percentage; Fagor style variablepeck drilling; Pecking/drilling of Tapered squares; and Peck chamfering.
•
MDDs (*.mdd files) supporting custom drill cycles for: 3-axis vertical mill, 5-axis vertical
mill, and 2-axis horizontal lathe.
•
Sample parts (*.vnc files) illustrating the use of custom drill cycles.
•
A single *.zip file containing all the files mentioned above.
Installing a sample package for custom drill cycles is simple. In your global data folder (such as
C:\ProgramData\Gibbs\GibbsCAM\10\):
1.
Under its Macros\ folder, create new subfolder CustomDrillCycles\ and move the
Gibbs.*.Generic\ folders into it.
2. Change to its MDD\ folder and move the sample *.mdd files into it.
3. Place the sample part files (*.vnc) wherever you like.
After your
C:\ProgramData\...\Macros\CustomDrillCycles\Gibbs.PeckDistance.Generic\ folder
is populated and your C:\ProgramData\...\MDD\ folder contains the sample MDD referenced
by the part, simply open a sample part and look at each of its processes. For example:
•
In the 3-axis Mill part, Mill3a.vnc, .the Holes process dialog’s Drill tab offers a pull-down
of custom drill cycles under Entry/Exit Cycle when the bottommost option button is selected.
To view or adjust parameter values, click User Cycle Data.
•
In the Lathe part, Lathe2a.vnc, .the Holes process dialog offers a pull-down of custom drill
cycles under Entry/Exit Cycle when the bottommost option button is selected. To view or
adjust parameter values, click the User Cycle Data the button.
22
•
In the 5-Axis part, Mill5a.vnc, the Drilling Options tab shows pull-down options when
Custom Cycle is selected. To view or adjust parameter values, click the Define Custom Data
button.
Operation Modifiers
When you right-click an operation and choose Operation Modifiers, the Manage Modifiers dialog
presents a list of operation modifiers. The left pane shows all modifiers available for the
operation type; the right pane shows all that have been assigned to the selected operation.
Each time you add a modifier, its modifier dialog appears. The parameter settings for most
modifier dialogs are the same as for the corresponding plug-in, except for the omission of
controls for selecting operations or creating new operations. You can add multiple instances of
some modifiers, such as Change Feeds and Speeds. Others, such as 5-Axis Toolpath Conversion, can
be added only once.
In the list of assigned modifiers, you can change the order in which they are applied, and you
can disable or enable one or more modifiers. Click the Edit button (or double-click the
modifier) to view or edit parameter settings.
When you click Do It, the operation is modified: The operation tile is marked with a plus
sign (+) in its lower left corner, and the corresponding toolpath is regenerated.
You can combine multiple Operation Modifiers, but you need to exercise caution applying two
(or more) modifiers that both change toolpath. The general guideline is: Use common sense. For
example, it would make no sense to combine a Z Ramp Contour modifier with a Z Step
Contour. Other specific caveats are noted below.
Notes for Using Operation Modifiers
l
Operation modifier data is stored with each operation, not with the process or process
group. For example, if a process group is associated with three operations, applying a
modifier to the second operation has no effect on the first or third.
23
l
l
l
l
l
l
You cannot save modifiers independently of the operation. You cannot copy or transfer
modifiers from one operation to another.
Modifiers are applied sequentially, without inter-modifier communication: The ending
state of modifier n is the starting state of modifier n+1. Therefore, the toolpath could
change significantly if the same set of modifiers were to be stacked in a different order.
Clicking CAM palette button Redo preserves existing modifiers, but clicking CAM palette
button Do It does not; it creates one or more new operations without copying modifiers.
Do not combine a conversion modifier (such as 5-Axis Toolpath Conversion or Convert to
Trochoidal) with any other modifier, except to follow it with Change Feeds and Speeds or
Transform Toolpath.
Do not combine Z Ramp Contour with Z Step Contour, and do not precede either with
Change Feeds and Speeds . However, it is perfectly acceptable to follow Z Ramp Contour (or Z
Step Contour , but never both combined) with Change Feeds and Speeds .
When using Z Step Contour, the Prefer Subs and Cutter Radius Compensation options are
not supported.
Managers for Tools, Processes, and Operations
GibbsCAM 2011 provides interfaces that let you see all your tools at once (Tool Manager) or see
all processes in a group (Process Manager), or all operations that have been created (Operations
Manager).
Viewing Tool/Process/Operation Data
In each of the Manager interfaces, you can do any of the following:
•
Choose which columns to display and in which order.
•
Sort the display either with a simple click on the column header or by using multi-level sort.
•
Sort the entire tile list, or find tiles and move them within the list.
•
Open the corresponding Tool/Process/Operation dialog.
24

Production Mill, Lathe, and Mill/Turn
Production Mill, Lathe, and
Mill/Turn
For Mill, Lathe, Mill/Turn, and 5-Axis: Custom drill cycles, such as Variable Peck, can be called
from the Drill tab of the Holes process and from the 5-Axis Drilling Options tab. As an example, a
set of macros is supplied to illustrate custom drill cycles for Variable Peck. When the support
files (macros and custom MDD) are installed, the functionality is visible to end users as
additional pull-down options among the Entry-Exit Cycle choices, as shown below.
For details on how to download sample packages for custom drill cycles, see “Holes and Hole
Features” on page 20.
For Mill and Mill/Turn: The Holes process provides a new option in the Drill tab. When making
multiple passes over dozens or hundreds of holes, you want to minimize unnecessary moves.
The new checkbox, Reverse Order, lets you reverse the drilling sequence.
Other improvements are Mill-specific or Lathe-specific:

Depth First support for pocketing with Material Only.
Improved Material Only. behavior (scallop cleanup) when Minimum Cut is set to 0.
Non-broken finish passes with open sides.
Mixed-shape pocketing.
A new tab, Offset/Trim, gives you finer control over toolpath for offset pocketing
operations. For example, when a pocket has an air wall, you can use Trim to Material
(affecting outside fills and inside voids) to avoid burying the tool in the material.

Lathe: B-Axis Turning
For Lathe machining, the Contour process dialog offers a new tab: B-Axis.
What Is B-Axis Turning?
B-axis turning machines provide features similar to a 5-axis mill machine. A lathe that supports
B-axis turning lets machinists specify vectors on which the tool will rotate, allowing a part to be
cut in a single pass. The two principal benefits of B-axis turning are fewer tool changes and the
ability to cut parts in which there would normally not be enough clearance.
The above image shows how GibbsCAM depicts a B-axis path that uses selected vectors. The
green vector lines with blue arrows mark positions at which the tool holder will rotate, and to
what degree.
For more information, see the Lathe guide.
Effect on Settings in the Contour Tab
Selecting the Vary B-Axis checkbox in the B-Axis tab can affect states and settings in the Contour
tab, as follows:
•
The Cut Off checkbox is unselected and unavailable.
28
•
The No Drag checkbox is unselected and unavailable.
•
The Use Auto Clearance checkbox is unselected and unavailable.
•
Under Contour Style:
•
The Material Only option is unselected and unavailable.
•
The Full option is selected, and a value of 0 is used for Corner Break.
Unselecting the Vary B-Axis checkbox automatically restores all affected controls in the Contour
tab to their previous states and settings.
Caveats
B-axis toolpath animation is supported by Flash CPR and Simulation but not by CPR.
In B-axis toolpath, collisions between tools and holders are not automatically detected.
Lathe: Groove Cycles
A new Lathe plug-in, Groove Cycle, designed around the Fanuc-style canned cycles for G74 and
G75 output, allows you to cut geometry-independent rectangular grooves. You can choose OD,
ID, or Face (or Back Face for MTM machines) and specify peck depth and stepover.
Lathe/MTM: Thread Whirling
Thread Whirling is a machining process where the cutters are mounted on the inside of
a cutting ring or cutting holder rather than the outside of a milling tool.

Entry Clearance Diameter/Radius
The tool will rapid to this diameter/radius before beginning the threading cuts. The tool will
also return to this value for each new cutting pass.
Exit Clearance Diameter/Radius
The tool will rapid to this value after completing the threading process. The tool will also
move to the next operation at this X value.
In X and In Z
For X - This represents the Xr component of the Run In move. There are several specific
behaviors available. If this is equal to the Z Run In, the entry will be 45 degrees from the
taper slope. A value of zero will be a straight Run In and will continue the taper.
For Z - This is the incremental distance to position to the right of the true thread start. A
value of 0 will start the tool exactly at the thread start. Please note that the Z axis value is
not measured along the taper and only positive values are valid.
Out X and Out Z
For X - This represents the Xr component of the Run Out move. There are several specific
behaviors available. If this is equal to the Z Run In, the entry will be 45 degrees from the
taper slope. A value of zero will be a straight Run Out and will continue the taper.
For Z - This is the incremental distance to position for the tool to over-travel at the left of
the true thread end. A value of 0 will stop the tool exactly at the thread end. Please note that
the Z axis value is not measured along the taper and only positive values are valid.
30
Start X and Start Z
These values represent the absolute position of X and Z at the start of the thread.
End X and End Z
These values represent the absolute position of X and Z at the end of the thread.
Positions
Approach
This is the Z approach position. The Whirling tool will rapid to this point in Z before
rapiding to the start position of the toolpath.
Retract
This is the Z retract position. The Whirling tool will rapid to this point in Z after completing
the Thread Whirling process.
Angle Offset
Offset
This checkbox enables Start/End Angle Offset values. This will allow you to set the rotary
axis for a part that needs the start or end of the thread to be oriented to a specific angular
value. This will be output in G-Code, but will not render.
Offset Angle Start
Rotary angle at which to start the process.
Offset Angle End
Rotary angle at which to end the process.
Parameters
Number of Teeth
Number of teeth for the Thread Whirling tool.
Feed per Tooth
Allows the Rotary Axis feed rate to be calculated per tooth. Toggling Constant Feed rate will
override this value.
Constant Feed rate
This will override the Feed per Tooth with a desired feed rate in degrees per minute.
TPI/Pitch
Pitch represents the distance measured in millimeters from one thread to the next. TPI is the
number of threads per inch.
Rotation Speed
This sets the tool spindle speed. The part spindle speed will be controlled by the rotary axis
feed rate.
Coolant
Toggle coolant on or off and a drop-down box with coolant choices. Flood is standard.

5-Axis
5-Axis
The 5-Axis module has been updated to take advantage of multi-threading, and now offers
drilling functionality and important new machining strategies for toolpath generation. Toolpath
smoothing and link move smoothing are significantly improved, and a large number of other
enhancements have also been made.
Highlights are summarized below. For details, refer to the 5-Axis guide.
Background Task Management
5-Axis is now multi-threaded; you can now run multiple independent processes simultaneously,
depending on the number of CPU cores under the control of your computer. After you click
Do It to start computing 5-axis toolpath, a new Task Manager facility allows you to view and
control the tasks as they are processed.
5-Axis Drilling Options
You can now use 5-Axis for drilling, tapping, and pecking, as well as for custom drilling cycles.

5-Axis
New Machining Strategies for Toolpath
Generation
In previous releases, 5-axis machining strategy used a surface-based approach to calculating
toolpath. With GibbsCAM 2011, we are pleased to make available the following additional
strategies.
Triangle Mesh
Triangle Mesh provides the following toolpath patterns:
•
Rough: To quickly remove material in planar layers perpendicular to the tool axis.
•
Parallel cuts : To machine a 3D component using toolpath passes that are parallel to each
other relative to the angle you specify in the XY plane.
•
Project Curves : Allows you to project a 2D curve pattern — Radial, Spiral, Offset, or user-
defined — onto the triangle mesh to create toolpath.
•
Constant Z : To machine a 3D component using toolpath passes that are parallel to the XY
plane.
•
Constant Cusp: To create a cut pattern with constant distance between contours; cusps that
are created will have the same height.
•
Flatlands : To machine true flat areas of a 3D component using toolpath passes that are offset
from the boundary of the flat area.
•
Pencil: To automatically detect inlying edges and create a single toolpath along them.
•
Projection: To create line projections on machining surfaces, especially for rotary machining.
Wireframe
Wireframe works without any machining surfaces, using drive curves and orientation lines.
36
5-Axis
Swarf Machining
SWARF is an acronym for Side Wall Axial Relief Feed. Swarf Machining is often used for turbine
parts where the goal is to produce the target surface with only one cut, using the entire flute
length of the tool. Tilt cycles control the tool axis orientation.
