Grinding-Specific Tool Offset and Tool Monitoring (W4)
Online tool offset
Example:
Existing conditions:
Figure 18-12 Straight line with gradient 1
Write online tool offset continuously
PUTFTOCF(<polynomial no.>, <reference value>, <length1_2_3>, <channel no.>, <spindle no.>)
PUFTOCF
Polynomial no.:
Reference value: Reference value of function
Length 1_2_3:
Channel no.:
Spindle no.:
The online tool offset is activated before the dresser axis movement block.

At the time of definition, the function value y should be equal to 0
and should be derived from machine axis XA (e.g. dresser axis).
