14.27.5 Rotation with Tool Tip as Center

A rotary axis travel command is processed as "Rotation with the tool tip as the center". Manual feed is carried out using the
rotary axes and the three linear axes so that the positional relationship between the workpiece and tool tip can be kept.

14.27.5.1 Machine Configuration - Tool Tilt Example

Tool orientation is changed without moving the tool tip.
The below example is the operation with the 1st handle in the tool tilt type B-C axis configuration, when #7936 (Height axis
rotation center offset) is set to "10.".
[Operation step]
(1) Select the handle mode.
(2) Select "Rotation with the tool tip as the center" (YD27/1).
(3) Confirm the in tool center point rotation (XD27) signal.
(4) Select the tool direction (YD1B/1, YD1C/0, YD1D/0) as a hypothetical coordinate system.
(5) Set "#8043 Tool HDL FD OFS".
(6) Rotate around the B axis by +45°.
Travel in the X and Z directions
without moving the tool tip,
according to the rotation angle.
