Because even complex contours present no problems
If you cannot take over complex drawings from the CAD (see Page 26), the CNC plus offers you the
possibility to translate even difficult drawings, e.g. drawings with complete dimensions, without having
mathematical knowledge.
Basics for this construction is the Graphical dialog by KELLER.

Because you save costs using the CNCplus
Example 1: Automatic residual quantity detection
This workpiece is to be machined.
Without CNC plus
With CNC plus
• Programming with G and M functions (with
the functionality of the control system
probably more than 2 hours)
• Geometry: 10 min
• First, roughing using the milling cutter
∅ 50mm
• Roughing residual quantities using the milling cutter
∅ 20mm
∅ 50mm
sz = 0.1mm
a = 20mm
∅ 20mm
sz = 0.05mm
a = 10mm
∅ 20mm
sz = 0.05mm
Total time for the production:
18:37 min
Total time for the production:
10:12 min
When calculating a machine cost of 50€ per hour
and the wages of 30€ per hour this results in:
* without taking the additional time required for programming
into consideration
6
Savings of
11 € per workpiece*
1.3.2
Example 2: Avoiding a crach
This workpiece is to be
machined.
The software recognizes when a tool is used that cannot remove the chips deep enough.
In this case, the boring holes are predrilled using the 6.8 mm drill.
During the calculation of the traversing
paths, the software signals a crash.
The depth of the boring holes (35mm) cannot
be reached using the tool (grooving chip
length 30mm)!
In the 3D view it is clealy visible, that the holder of the drill touches down!
This type of crash can get extremely expensive, particularly, when a HSC spindle
was used!

Because our plus systems have proven themselves worldwide
The plus systems are used in over 60
countries by more than 5000 customers.
An this is what our customers say:
Mr. Krüger
"The qualified workers can again concentrate on the essential parts of their work
and do not have to spend time dealing with the programming of blocks."
Mr. Wege
"The expectations with regard to flexible and economic production
were surpassed by far."
Mr. Litim
"During the 15 years that our company has been in business, we
have grown into a sound and continuously expanding, medium-sized
company. We presently have 24 employees and process
more than 15t of steel per day. This successful developement
can be greatly attribututed to the use of your excellent software."
Mr. Braun
"Our trainees have thoroughly enjoyed working with the
new qualification concept. It has been confirmed that the criteria "Comprehensibility"
and "Maximum performance" are very important factors in a software."
Mr. Jagla
"This software is easily understood, easy to handle and quickly learned."
Mr. Ebner
"NC programs generated with CAMplus* can be processed in all of the CNC control systems
used by us (16 different control systems)."
*CAMplus is integrated in CNCplus.
Mr. Schneider
"This 50% reduction of the production time in addition to the convenient
creation of the program contributes greatly to the cost reduction."
Mr. Pyka
"It is incredibly thrilling for me to process demanding workpieces
using your software."

Your first workpiece with CAMplus
This example will introduce you to the basics of operating the CNC plus . Notice on the right-hand side,
how easy you reach the first workpiece.
As this is a very simple workpiece, the geometry is entered directly in the workplan.

2.3.3
Workplan CAM3
Based on workplan CAM2, we can see here how drastically the production time is reduced by the
intelligent CAM software. The "secret":
Automatic residual material detection.
The 'only' difference between workplans CAM2 and CAM3 is that 3 work steps are added at the beginning
of CAM3.

A ∅ 34 mm drill is used for
pre-drilling because the
following 6 tip shank-type cutter
of ∅ 30 mm cannot cut in.
B Rough milling of large inner surfaces
As you can see, the shank-type cutter automatically finds the start hole. Notable time saving can be
achieved by using this shank-type cutter with a very large diameter.

C
Rough milling of 2 large residual surfaces
D
Rough milling of all residual inner surfaces
E-J The work steps finishing all inner contours with T8, groove milling with T7, centring with T1, drilling

Apply the work step without simulation

to the workplan or group the work steps with F5 Select / F2 Add all followed by F4 Perform.
You can, of course, simulate each work step again, if you choose to do so.
Production time here:
Production time with CAM2:
Time saving due to the software intelligence:

approx. 40%
When you open the workplan CAM3 already saved in the software, you will find a work step Contour
in the depository folder. When you execute this work step, all contours will be automatically deburred
at 1x45°.

Geometry for professionals
This workpiece contains 2 complex contours. Prior to creating the geometry using CNC plus , you must
first develop an idea of the type and manner of the design. This takes most of the time!
To shorten this time, you are shown these 2 contours with detailed dimensions on the right-hand side.
Remark: The 40 mm radius in the original drawing is not used in the detailed dimensioning, because
this radius results from the design (as you will see later with F7 Information , the radius is exactly
39.999 mm).

When you have created the design several
times, you should be able to repeat it in less
than 10 min when you work as a professional
(see page 54).
We know persons who are able to master this
geometry in less than 5 min!
If you take this geometry from CAD, this takes
less than 1 min.
If you want to: Compare your design values
with the saved design (folder Exemplary
geometries / DEMO-HU).
You can view the 3D simulation after opening
the respective workplan (Folder Exemplary
workplans / DEMO-HU) and starting the 3D
simulation.
56
Lines and arcs are numbered in the order of the design.
External contour
Due to the symmetry, the external contour is subdivided
into 6 segments. If you have created this design, you have
to enter this contour Turning with Copy and join and enter
the value 5 in the Number field.

8. Select the first line and

Then insert the rounding.
Internal contour
Prior to starting the design, "create" the centre points for
the 3 circles with R25.
The simplest solution is a triangle with the
peripheral ∅ of 30 mm and a 180° angle position:
The points of the triangle represent the 3 centre points.
1. Start the design with
an arc with the starting point
X-40 / Y0, the centre point X-15 / Y0
