9.8 3-stage surface grinding (roughing, finishing and fine-finishing) - CYCLE409
Programming example
Machining sequence:
● Grind surface at a grinding wheel peripheral speed of 20 m/s.
● In part program block N30: air allowance of 0.05 mm and roughing allowance of 0.05 mm,
● Infeed of 0.03 mm per stroke with acoustic emission sensor and 0.02 mm infeed for
● 1 sparking-out stroke following roughing, 2 strokes following finishing, and 3 strokes
● Single-stroke dressing for finishing and fine-finishing respectively.
● 2 strokes prior to finishing, 1 stroke prior to fine-finishing.
● Off-loading value of 0.03 mm following roughing and 0.015 mm following finishing.
● With roughing, infeed is performed continuously in Z.
● With finishing and fine-finishing, infeed is performed intermittently.
