PUFTOCF
Polynomial no.: Number of function (1, 2, 3)
Reference value: Reference value of function
Length 1_2_3: Wear parameter into which the tool offset value is added
Channel no.: Channel in which the offset is to be effective
Spindle no.: Spindle for which the online offset is to be effective
The online tool offset is activated before the dresser axis movement block.
