Fig. 10.4.11 (b) Spindle Center Compensation
Shifting the control point
Conventionally, the center of a rotation axis was used as the control
point. The control point can now be shifted as shown in the figure
below.
Then, when the rotation axis is at the 0-degree position also in tool
length compensation along the tool axis (G43.1), the control point can
be set to the same position as that for ordinary tool length compensation
(G43).
The control point here is indicated with machine coordinates.
When linear interpolation is specified, for example, this control point
moves linearly.
