Sequence of operations
The machining start position is first approached in X, then in Z, corresponding to the initial
position of the wheel in X, if the current X value is less than the X allowance.
The starting positions in X and Z are determined as follows:
Internal radius: X = X starting position + roughing allowance + air allowance
Z = Z shoulder dimension + workpiece radius - wheel radius + roughing allowance
External radius: X = X starting position - wheel radius
Z = Z shoulder dimension + roughing allowance + air allowance
Sparking can be performed optionally with direct-contact vibration pick-up, for inner circle in
the X axis, for an outer circle in the Z axis.
The roughing operation is followed by retraction.
