2. Direction of the offset
The offset direction is indicated in the figure below regardless of the
G41/G42 mode.
G90 G94
When one of following cycles is specified, the cycle deviates by a tool
nose radius compensation vector. During the cycle, no intersection
calculation is performed.
G71 (Stock removal in turning or traverse grinding cycle)
G72 (Stock removal in facing or traverse direct constant–dimension
grinding cycle)
G73 (Pattern repeating or Oscillation grinding cycle)
G74 (End face peck drilling)
G75 (Outer diameter/internal diameter drilling)
G76 (Multiple threading cycle)
G78 (Threading cycle)
