Simulating machining
7
7.1
Overview
During simulation, the current program is calculated in its entirety and the result displayed in
graphic form. The result of programming is verified without traversing the machine axes.
Incorrectly programmed machining steps are detected at an early stage and incorrect
machining on the workpiece prevented.
Graphic display
The simulation uses the correct proportions of the workpiece, tools, chuck, counterspindle and
tailstock for the screen display.
For the spindle chuck and the tailstock, dimensions are used that are entered into the "Spindle
Chuck Data" window.
For non-cylindrical blanks, the chuck closes up to the contour of the cube or polygon.
Depth display
The depth infeed is color-coded. The depth display indicates the actual depth at which
machining is currently taking place. "The deeper, the darker" applies for the depth display.
Definition of a blank
The blank dimensions that are entered in the program editor are used for the workpiece.
The blank is clamped with reference to the coordinate system, which is valid at the time that the
blank was defined. This means that before defining the blank in G code programs, the required
output conditions must be established, e.g. by selecting a suitable zero offset.

Machine references
The simulation is implemented as workpiece simulation. This means that it is not assumed that
the zero offset has already been precisely scratched or is known. In spite of this, unavoidable
MCS references are in the programming, such as for example, the tool change point in the
MCS, the park position for the counterspindle in the MCS or the position of the counterspindle
slide. Depending on the actual zero offset - in the worst case - these MCS references can mean
that collisions are shown in the simulation that would not occur for a realistic zero offset - or vice
versa, collisions are not shown, which could occur for a realistic zero offset. This is the reason
why in ShopTurn programs, in the case of a simulation, the program header calculates an
