Simulating machining
6.1 Overview
Determining the program runtime
The program runtime is determined when executing the simulation. The program runtime is
temporarily displayed in the editor at the end of the program.
Properties of simultaneous recording and simulation
Traversing paths
For the simulation, the displayed traversing paths are saved in a ring buffer. If this buffer is
full, then the oldest traversing path is deleted with each new traversing path.
Optimum display
If simultaneous machining is stopped or has been completed, then the display is again
converted into a high-resolution image. In some cases this is not possible and the following
message is output: "High-resolution image cannot be generated".
Working zone limitation
No working zone limits and software limit switches are effective in the tool simulation.
Start position for simulation and simultaneous recording
During simulation, the start position is converted via the work offset to the workpiece
coordinate system.
The simultaneous recording starts at the position at which the machine is currently located.
Restrictions
● Traori: 5-axis motion is linearly interpolated. More complex motion cannot be displayed.
● Referencing: G74 from a program run does not function.
● Alarm 15110 "REORG block not possible" is not displayed.
● Compile cycles are only partly supported.
● No PLC support.
● Axis containers are not supported.
Supplementary conditions
● All of the existing data records (Toolcarrier / TRAORI, TRACYL) are evaluated and must
be correctly commissioned for correct simulation.
● Transformations with swiveled linear axis (TRAORI 64 - 69) as well as OEM
transformations (TRAORI 4096 - 4098) are not supported.
● Changes to the toolcarrier or transformation data only become effective after Power On.
● Transformation change and swivel data record change are supported. However, a real
kinematic change is not supported, where a swivel head is physically changed.
● The simulation of mold making programs with extremely short block change times can
take longer than machining, as the computation time distribution for this application is
dimensioned in favor of the machining and to the detriment of simulation.
