· Actual position: Display hide actual value of simulated channel
axes (Note: TRANS, ROT, SCALE and MIRROR are not taken into
account in the actual value display).
· NC block: Activate/deactivate display of current NC block
· Machining time: Activate/deactivate display of the calculated
machining time in the header of the basic simulation window
(T = calculated machining time (from the programmed feedrates)
å = machining time + sum of all estimated down times).
· Always reload tools
* In position "on" (default setting), all the necessary tool data are
reloaded on each program change.
* In position "off", tool data are only reloaded if required, if the
timestamp is altered (automatic query). Otherwise, the existing
tool environment is not changed.
· Save tool path
*
In position "on" (default setting), all the tool paths in the
simulation sequence are visualized and stored temporarily in
the model for future display (zoom, etc.).
*
In position "off", the resulting tool paths are visualized once
and not stored temporarily in the model. When the display is
subsequently manipulated (e.g. Zoom +), the tool paths are
lost.
· Block-by-block processing
*
In position "on", discontinuous path processing, but largely
accelerated (reduced number of IPO interpolation points, for
example, only at block end points on straight lines).
*
In position "off" (default setting), largely continuous path
processing (constant distance between interpolation points
depending on the IPO setting).
· Waiting for dwell times
*
In position "on", program instructions with dwell times cause
real dwell times in the simulation.
*
In position "off" (default setting), the dwell is suppressed in the
simulation and the dwell times are only taken into account in
time calculations.
