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 represented on the screen uses the correct workpiece and tool proportions.
For simulation at milling machines, the workpiece is located, fixed in space. Only the tool
moves, independent of the machine type.
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 work offset.
Programming a blank (example)

CYCLE800(0,"TABLE", 100000,57,0,0,0,0,0,0,0,0,0,-1,100,1)
WORKPIECE(,,,"Box",112,0,-50,-80,00,155,100)
T="NC-SPOTDRILL_D16
Note
Blank offset for a changed work offset
The blank is always created in the work offset which is presently active.
If you select another work offset, then the coordinate system is converted, however, the display
of the blank is not changed.
Note
Blank clamping
If your machine has various blank clamping options, enter the required clamping in the program
header or in the blank screen.
Note also the machine manufacturer’s instructions in this regard.
Display of the traversing paths
The traversing paths are displayed in color. Rapid traverse is red and the feedrate is green.
