13.7 Tool length compensation (#TLC)
It must be used with CAD-CAM generated programs and the tool to
be used does not have the same dimensions.
The #TLC compensates for the length difference; but it does not
compensate for the radius difference.
CAD-CAM programs take the tool length into consideration and
generate the coordinates for the tool base.
When using the #TLC function (Tool Length Compensation) the CNC
compensates the length difference between both tools, the actual
(real) one and the theoretical (calculated) one.
To work with tool length compensation (#TLC), use the following
instructions:
The TLC function cannot be selected while the RTCP function is
active.
#TLC ON [n] Turn TLC on.
n: Tool length difference (real - theoretical).
#TLC OFF Turn TLC off.
Examples:
N10 #TLC ON [1.5] (Turn TLC on with a tool that is 1.5mm. longer)
N100 #TLC OFF (Turn TLC off)
N200 #TLC ON [-2] (Turn TLC on with a tool that is 2mm. shorter)
N300 #TLC OFF (Turn TLC off)
