Function
The blank is used for the simulation and the simultaneous recording. A useful simulation can
only be achieved with a blank that is as close as possible to the real blank.
Create a separate program for each new workpiece that you would like to produce. The
program contains the individual machining steps that are performed to produce the
workpiece.
For the blank of the workpiece, define the shape (cuboid, tube, cylinder, polygon or centered
cuboid) and your dimensions.
Manually reclamping the blank
If the blank is to be manually reclamped from the main spindle to the counterspindle for
example, then delete the blank.
