HEIDENHAIN CNC PILOT 4290 139
Cycle radius 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.
Parameters
X, Z: Corner point (X diameter)
B Radius
E Reduced feed – default: Active feed
■ Cutter radius compensation: Active.
■ Allowances are not calculated.
Cycle chamfer 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.
Parameters
X, Z: Corner point (X diameter)
B Chamfer breadth
E Reduced feed – default: Active feed
■ Cutter radius compensation: Active.
■ Oversizes are not taken into account.
