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.
Example:
FCTDEF(1, -100, 100, -$AA_IW[X], 1)
PUTFTOCF (1, $AA_IW[X], 1, 2, 1)
Length 1 of tool for spindle 1 in channel 2 is modified as a function of X axis movement.
Note
The online tool offset for a (geometric) grinding tool that is not active can be activated by
specifying the appropriate spindle number.
If the channel number is omitted, the online offset is effective in the same channel.
If the spindle number is omitted, the online offset is applied to the current tool.
An online tool offset can also be called as a synchronized action.
