The grinding-wheel cutting and dresser cutting are compensated
continuously during grinding in the canned cycles for surface grinding
(G75, and G77 to G79). They are compensated according to the amount
of continuous dressing.

The offset number (grinding-wheel wear compensation number) is
specified by address L in the block for the canned cycles for surface
grinding. The compensation amount set in the offset memory
corresponding to the specified number is the dressing amount.
Compensation is performed for each cutting operation (each X-axis
movement) in the canned cycles for grinding. Along with X-axis
movement, compensation is performed both in Y-axis direction
(grinding-wheel cutting) and that in V-axis direction (dresser cutting).
That is, compensation is performed for interpolation for the three
coordinates simultaneously. The Y-axis movement amount
(compensation amount) is the specified dressing amount. The V-axis
movement amount is twice the specified dressing amount (diameter).
