After a new workpiece detail magnification is
selected, the control "forgets" previously simulated
machining operations. The TNC then displays
machined areas as unmachined areas.
If the workpiece blank cannot be further enlarged or
reduced, the TNC displays an error message in the
graphics window. To clear the error message, reduce
or enlarge the workpiece blank.
Repeating graphic simulation
A part program can be graphically simulated as often as desired,
either with the complete workpiece or with a detail of it.
Function Soft key
Restore workpiece to the detail magnification in
which it was last shown
Reset detail magnification so that the machined
workpiece or workpiece blank is displayed as it was
programmed with BLK FORM
With the WINDOW BLK FORM soft key, you return
the displayed workpiece blank to its originally
programmed dimensions, even after isolating a detail
without TRANSFER DETAIL.
Tool display
You can display the tool during simulation in the plan view and
in the projection in three planes. The TNC depicts the tool in the
diameter defined in the tool table.
Function Soft key
Do not display the tool during simulation
Display the tool during simulation
