ls Radius cycle G87
G87 machines transition radii at orthogonal, paraxial inside and outside
corners. The direction is taken from the position/machining direction
of the tool.
A preceding longitudinal or transverse element is machined if the tool
is located at the X or Z coordinate of the corner before the cycle is
executed.
Chamfer cycle G88
G88 machines chamfers at orthogonal, paraxial outside corners. The
direction is taken from the position/machining direction of the tool.
A preceding longitudinal or transverse element is machined if the tool
is located at the X or Z coordinate of the corner before the cycle is
executed.
