Detailed Description
2.4 Tool: Tool radius compensation 2D (TRC)
Tool Compensation (W1)
Function Manual, 08/2005 Edition, 6FC5397-0BP10-0BA0
2-59
The following conditions must be true for retraction:
• Smooth retraction is activated in block N60
• Retraction movement performed with quadrant (G248) and helix (G340)
• FAD not programmed, since irrelevant for G340
• Z=2 in the start point; Z=8 in the end point, since DISCL=6
• When DISR=5, the radius of SAR contour=20; that of the tool center point path=5
• After the circle block, the retraction movement leads from Z8 to Z20 and the movement is
parallel to the XY plane up to the end point at X70 Y0.
