Programming example - 1
Machining sequence:
● Plunge cut in Y direction at a peripheral speed of 20 m/s.
● In part program block N30: allowance of 0.1 mm, acoustic emission sensor, and 0.1 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.
● Off-loading value of 0.03 mm following roughing and 0.015 mm following finishing.
