17.12 Camera-based monitoring of the setup
situation VSC (option 136)
Basics
Application
Refer to your machine manual.
This feature must be enabled and adapted by the
machine tool builder.
Camera-based checking of the setup situation (option 136 Visual
Setup Control) allows you to monitor the current setup situation
before and during processing, and to compare this with a safe
target status. After setup, simple cycles for automatic monitoring
are available.
A camera system generates reference images of the current
workspace. With Cycles 600
GLOBAL WORKING SPACE
or 601
LOCAL WORKING SPACE
, the control produces an image of the
working space and compares the image with previously prepared
reference images. These cycles may alert to discrepancies in the
workspace. The operator decides whether the NC program is
interrupted in the event of an error or continues to run.
Using VSC offers the following advantages:
The control can recognize elements (e.g. tools, fixtures, etc.)
that are in the working space once the program has started
If you always want to clamp a workpiece at the same position
(e.g. hole at top right), the control can check the clamping
situation
For documentation purposes you can generate an image of the
current workspace (e.g. of a clamping situation that is rarely
used)

Requirements
As well as option number 136, a HEIDENHAIN camera system is
required for VSC functions.
You must create an adequate number of reference images to allow
the system to compare the situation reliably.
