14.27.4.2 Coordinate System Selection - Table Coordinate System Example

Axis travel is performed in each of the X, Y and Z directions on the rotating table surface.
The below example is the operation with the 1st handle in the table tilt type B-C axis configuration.
[Operation step]
(1) Select the handle mode.
(2) Select the table coordinate system (YD1B/0, YD1C/1, YD1D/0) as a hypothetical coordinate system.
(3) Travel in the X direction by "100". and in the Z axis direction by "50". from the workpiece coordinate zero point.
Rotate around the C axis by +90° and around the B axis by -45°.
