Transition radii G87
G87 machines transition radii at orthogonal, paraxial inside and outside
corners. The direction for the rounding 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.
Parameters
X, Z: Corner point (X diameter)
B
Radius
E Reduced feed rate – no input: active feed rate
• Cutter radius compensation: is carried out
• Allowances are not considered.
Chamfer G88
G88 machines chamfers at orthogonal, paraxial outside corners. The
direction for the chamfer 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.
Parameters
X, Z: Corner point (X diameter)
B
Chamfer width
E Reduced feed rate – no input: active feed rate
• Cutter radius compensation: is carried out
• Allowances are not considered.
