19.7 Correct the implicit tool length compensation of the program
(#TLC).
CAD-CAM programs take the tool length into consideration and generate the coordinates
for the tool base. The instruction #TLC must be used with CAD-CAM generated programs
and the CNC does not have a tool with the same dimensions. 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. The #TLC compensates for
the length difference; but it does not compensate for the radius difference.
Programming. Turn tool length compensation (TLC) on.
When defining this instruction, one must define the length difference between the real tool
and the theoretical one used to write the program.
Programming format.
The programming format is the following; the list of arguments appears between curly
brackets.
#TLC ON [{long}]
Programming. Cancel tool length compensation (TLC off).
'This instruction must be programmed alone in the block'
Programming format.
The programming format is:
#TLC OFF
Considerations about the TLC.
• TLC compensation being active, the CNC only allows home search (G74) on the axes
not involved in TLC.
• TLC cannot be selected while the RTCP transformation is active.
• TLC compensation being active, the CNC does not allow modifying the active kinematics
(#KIN ID).
• TLC compensation being active, the CNC does not allow modifying the software limits
(G198/G199).
{long}
Tool length difference (real - theoretical).
#TLC ON [1.5]
(Turn on with a tool that is 1.5 mm longer)
#TLC ON [-2]
(Turn on with a tool that is 2 mm shorter)
#TLC OFF
