2 1/2D COMPENSATION with compensation plane determined
using G17 - G19
2 1/2D COMPENSATION with compensation plane determined
using a frame
Compensation perpendicular to path tangent and tool orientation
No changes in orientation in inserted circular blocks at external
corners. Orientation motion is performed in the linear blocks.
Travel path is extended by means of circles. The change in orien-
tation is also performed proportionately in the circle.
Constant orientation (3-axis). Tool points in the Z direction of the
coordinate system defined via G17 - G19. Frames do not have
any effect.
Constant orientation (3-axis), tool in Z direction of the coordinate
system currently defined via the frame.
5-axis with variable tool orientation
NC program relates to the contour on the machining surface.
The NC program relates to the tool center point path.
