5.3 Tool compensation
Introduction
The TNC adjusts the spindle path in the spindle axis by the
compensation value for the tool length. In the working plane, it
compensates the tool radius.
Tool length compensation
Length compensation becomes effective automatically as soon as
a tool is called. To cancel length compensation, call a tool with the
length L=0 (e.g.
TOOL CALL 0).
For tool length compensation, the control takes the delta values
from both the
TOOL CALL block and the tool table into account:
Compensation value =
L + DL
