Simulation
ShopTurn provides various extensive and detailed simulation functions for
displaying the simulation and the machining paths.
During simulation, the current program is calculated in its entirety and the
result is displayed in graphic form.
You can select the following modes of representation for simulation:
Side view
Face view
2 windowed view
The simulation uses the correct proportions for the tools and workpiece
contours.
The tool is displayed in yellow colour.
The traverse paths for the tools are shown in colour:
Red line = tool is moving at rapid traverse
Green line = tool is moving at machining feedrate
In all views, a clock is displayed during graphical processing. The
displayed machining time (in hours/minutes/seconds) indicates the ap-
proximate time that would actually be required to execute the machining
program on the machine (incl. tool change).
If a program is interrupted during simultaneous recording, the clock stops.
In addition, the current axis coordinates, the override, and the program
block currently being executed are also displayed.
The active tool with the cutting edge number and feedrate are also dis-
played in the simulation.
Transformations are displayed differently during simulation and simultane-
ous recording:
Coordinate transformations (translation, scaling, ...) are displayed as
programmed.
Cylinder surface transformations are displayed as a developed surface.
After swivel transformation, the previous machining operations are-
deleted from the display and only machining of the swiveled plane is
displayed (viewing angle perpendicular to the swiveled plane).
Zero offsets (G54, etc.) do not alter the zero in the graphical display.
This means that, in the case of multiple clampings, the machining op-
erations for each of the individual workpieces are plotted on top of one
another.
Note:
If you want to display a different portion of the workpiece from the one de-
fined in ShopTurn, you can define a new blank in the program (see section
5.3 in this module).
