Clearance cycle group
Line with radius G87
G87 machines transition radii at orthogonal, paraxial inside and outside
corners.
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 ex-
e c u t e d .
Parameters
X, Z:
Corner point (X as diameter)
B: Radius
E: Reduced feed rate – default: active feed rate
• Cutter radius compensation: is carried out
• Oversizes: are not considered
Line with chamfer G88
G88 machines chamfers at orthogonal, paraxial inside and outside
corners.
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.
Parameters
X, Z:
Corner point (X as diameter)
B: Chamfer width
E: Reduced feed rate – default: active feed rate
• Cutter radius compensation: is carried out
• Oversizes: are not considered
