5.5 Motion Simulation
The motion simulation depicts the workpiece blank
material as a ”filled surface” and ”machines” it
during simulation by ”erasing” the material. The tools
move at the programmed feed rate (program-run
graphics).
You can interrupt the motion simulation at any time,
even during simulation of an NC block. The display
below the simulation window indicates the target
position of the current path.
If other simulation windows are activated in addition
to the lathe window, the machining process is shown
as ”track-display graphics” in the supplementary
windows.
Protection zone and limit switch monitoring
In addition to the setting in the simulation, the
protection zone monitoring is also switched on in the
machine parameter 205, ... (”Monitoring on/off”).You
set the protection zone dimensions in the Setup mode
(Manual Control operating mode). The dimensions are
managed in the machine parameters 1116, ...
Visual limit switch monitoring
Depending on the ”limit switch for slide x” setting
(”slide settings” dialog box) the motion simulation
shows the positions of the software limit switches
relative to the tool point (red rectangle).That simplifies
monitoring the traverse paths near the working space
limits.The visual limit-switch monitoring is
independent from the protection zone monitoring and
limit switch monitoring.ng.
Back to main menu
Menu items for controlling the simulation
■ New: Start a new simulation (program changes
are taken into account)
■ Continue: Simulates the next NC source block or
basic block
■ Stop: Stops the simulation. Thus you can edit the
settings or use the ”contour follow-up” function.
”Set up – ...” drop-down menu:
■ ”... – Window”:
”... – Contour selection”:
„... – Status line”:
see ”
5.2 Main Menu.”
■ „... – Slide”: See ” 5.2 Main Menu.”
In the motion simulation you can also activate the
”limit switch display for slide x.”
5.5 Motion Simulation
■ ”... – Warnings”: see ” 5.1.2 Basics of Operation”
■ „... – Times”: see ” 5.9 Time Calculation”
■ „... – Protection zone – ...”: see ” 5.4 Machining Simulation.”
”Debug” drop-down menu
If you use variables to machine the workpiece, you can show and edit
them with the debug functions (see ”
5.8 Checking the NC Program
Run”).
”Contour” drop-down menu:
■ ”Contour - Dimension”: see ” 5.3.2 Dimensioning.”
■ ”Contour – 3-D view”: see ” 5.7 3-D View.”
Influence the traversing speed (by menu)
■ ”–”: slows the traversing speed.
■ ”>|<”: means traversing speed in real time.
■ ”+”: increases the traversing speed.
The simulation shows the limit switch dimensions relative
to the tool point. This is why the limit switch dimensions
are repositioned in a tool change.
