6.2 Cutting rate (SVC)
Further information
Tool radius
The following tool offset data (associated with the active tool) affect the tool radius when:
● $TC_DP6 (radius - geometry)
● $TC_DP15 (radius - wear)
● $TC_SCPx6 (offset for $TC_DP6)
● $TC_ECPx6 (offset for $TC_DP6)
The following are not taken into account:
● Online radius compensation
● Allowance on the programmed contour (
Tool radius compensation (G41/G42)
