Programming example
Machining sequence
● Oscillation with continuous infeed in Z direction at a grinding wheel peripheral speed of
20 m/s with two infeed blocks.
● In part program block N30: allowance of 0.1 mm and infeed of 0.005 mm per stroke, no
retraction at the end and, therefore, grinding immediately continues in part program block
N40 with an allowance of 0.02 mm and infeed of 0.002 mm per stroke.
● Both operations involve 2 sparking-out strokes. These are performed with the same
geometry positions.
● The per-stroke feedrate in X is 40 mm for the 1st operation and 10 mm for the 2nd.
● The fact that the start point of the second machining operation is precisely matched to an
end point of the first machining operation means that infeed can take place straight away.
In order for this to happen, grinding with an acoustic emission sensor must be
deactivated.
