Switch on TRC/MCRC G41/G42
G41 and G42 switch on the TRC and MCRC.
G41: compensation of the tool-tip/cutter radius to the left of the
contour in traverse direction
G42: compensation of the tool-tip/cutter radius to the right of
the contour in traverse direction
Parameters:
Q: Level (default: 0)
0: TRC on the turning plane (XZ plane)
1: MCRC on the front face (XC plane)
2: MCRC on the lateral surface (ZC plane)
3: MCRC on the front face (XY plane)
4: MCRC on the lateral surface (YZ plane)
H: Out (only with TRC – default: 0)
0: Intersecting areas which are programmed in directly
successive contour elements are not machined
1: The complete contour is machined—even if certain areas
are intersecting
O: Feed reduc. off (default: 0)
0: No
1: Yes
Please note:
Program G41/G42 in a separate NC block
Program a straight line segment (G0/G1) after the block
containing G41/G42
The TRC/MCRC is taken into account from the next path of
traverse.
