Sequence of operations
The machining start position is first approached in X, then in Z, corresponding to the initial
position of the grinding wheel in Z, if the current X value is less than the X allowance.
The Z starting position is calculated as the shoulder dimension in Z + roughing allowance +
air allowance.
The surface can be sparked using an acoustic emission sensor. Optionally, the reciprocating
motion is activated in X, and the subsequent roughing operation is performed by plunge-
cutting up to finishing allowance. After finishing and expiry of the sparking-out time, the
reciprocation motion stops, and the wheel retracts to the starting position.
