Fig. 5-33: How the D-corrections work in the process plane
Geometry registers L1, L2 and L3 are not used for compensation unless
tool length correction G48/G49 is active. Geometry register R is only used
for compensation when tool path compensation G41/G42 is active.
When tool management is active for a selected tool and a D-correction is
also active, the tool lengths and radius are calculated as follows:
Length correction L1 = Length L1 + Wear L1 + Offset L1 + L1 of the D correction
Length correction L2 = Length L2 + Wear L2 + Offset L2 + L2 of the D correction
Length correction L3 = Length L3 + Wear L3 + Offset L3 + L3 of the D correction
Radius correction R = Radius R+ Wear R + Offset R+ R of the D correction

Geometry registers L1, L2, L3 and R of the selected D-correction are
not active unless tool length correction (G48/G49) or tool radius cor-
rection (G41/G42) is active.
