4.3 Tool Compensation Values
For each tool, the TNC adjusts the spindle path in
the tool axis by the compensation value for the tool
length. In the working plane it compensates the
tool radius.
Effect of tool compensation values
Tool length
Length compensation becomes effective automatically as soon as a tool is
called and the tool axis moves.
To cancel length compensation, call a tool with the length L = 0.
If a positive length compensation was in effect before TOOL CALL 0, the clearance to the workpiece is reduced.
If the tool axis is moved immediately after a TOOL CALL, the difference in length between the old and new tools is
added to the programmed value.
Tool radius
Radius compensation becomes effective as soon as a tool is called and is
moved in the working plane with RL or RR.
To cancel radius compensation, program a positioning block with R0.
