12. Tool Offset Functions
(4) When I, J has been commanded in a block without movement
D1
Direction of offset vectors
(1) In G41 mode
Direction produced by rotating the direction commanded by I, J through 90° to the left from the
forward direction of the Z axis (axis 3) as seen from the zero point
(Example 1) With I100.
(2) In G42 mode
Direction produced by rotating the direction commanded by I, J through 90° to the right from
the forward direction of the Z axis (axis 3) as seen from the zero point
(Example 1) With I100.
