Example for radius grinding
Cycle for machining an internal radius of 10mm. The radius is machined in the following
sequence: First sparking with acoustic emission sensor to diameter 200 + stock allowance,
thereafter roughing to 200. Thereafter, the radius is machined up to shoulder dimension 55.
Additional specified values:
A_SR = 0.2 mm Roughing allowance
A_LU= 5 mm Air allowance

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 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 an acoustic emission sensor, for inner circle in the
X axis, for an outer circle in the Z axis.
The roughing operation is followed by retraction.
