3.9 Graphic Simulation
The graphic simulation feature enables you to check
the machining sequence, the proportioning of cuts
and the finished contour before actual machining.
In the Manual and Teach-in modes, this function
simulates the execution of a single cycle—in Program
run mode it simulates a complete cycle or DIN
program.
A programmed workpiece blank is displayed in the
simulation graphics. MANUALplus also simulates
machining operations that are executed with a
traversable spindle or the C axis on the face or lateral
surface. This allows you to check the complete
machining process.
In Manual mode and Teach-in mode, the cycle you are
currently working on is simulated. In the Program run
mode, the simulation of a cycle program always starts
from the cursor position. DIN programs are simulated
from the beginning of the program.
You can choose between wire frame graphics and
cutting path graphics. In addition, the motion
simulation graphics (erasing graphics) is available for
displaying turning operations. It is recommended to
use this graphic check in the "Program run" mode,
since it provides a good overview of the machining
process.
The wire frame graphics is particularly convenient if
you only need a quick overview of the proportioning of
cuts. The path of the theoretical tool tip, however, is
not identical with the contour of the workpiece. This
graphics is therefore not as suitable if you wish to run
a thorough check on the machined contour. In the
CNC, this "falsification" is compensated by the cutting
radius compensation.
The cutting path graphics accounts for the exact
geometry of the tool tip. Here, you can check whether
the contour is machined completely or needs to be
reworked, whether the contour is damaged by the
tool or overlaps are too large. The cutting path
graphics is especially useful for recessing, drilling and
milling operations where the tool shape has an
essential influence on the accuracy of the resulting
workpiece.
