Tool Radius Compensation feature
This allows workpiece dimensions to be entered directly from the
drawing. The displayed distance to go is then automatically
lengthened (R+), or shortened (R–) by the value of the tool radius. for
more information see "Presets" on page 19.
The length offset may be entered as a known value, or the VUE may
determine the offset automatically. The tool length is the difference in
length
Δ
L between the tool, and the reference tool. The length
difference is indicated with the “
Δ
“ symbol. The reference tool is
indicated by T1.
Sign for the length difference
Δ
L
If the tool is longer than the reference tool:
Δ
L > 0 (+).
If the tool is shorter than the reference tool:
Δ
L < 0 (–).
As indicated above it is also possible to have the VUE determine a
tool’s length offset. This method involves touching the tip of each tool
to a common reference surface. This allows the VUE to determine the
difference between the length of each tool.
Move the tool until its tip is touching the reference surface. Press the
TEACH LENGTH soft key. The VUE will calculate an offset relative to
this surface. Repeat the procedure for each additional tool using the
same reference surface.
Only the tools set using the same reference surface may
be changed without having to reset the datum.
