Tool length and radius setting
R14=t t= Tool offset edge to be updated (usually up to nine
edges).
R14=3 Updates the current tool offset, edge D3.
If R14 is not input, the current tool offset edge (D) is
updated. The current tool is the number of the tool in
the spindle.
R17=q q= Overtravel distance and radial clearance.
For details, see "Setting-data subroutine L9760" on
page 13.
Default value: 5.0 mm (0.197 in)
R18=r r= Diameter of tool.
This is the nominal diameter of the tool.
Default value: Maximum diameter of tool in
RENC[12].
R19=s s= Spindle speed at which length and diameter
measurement takes place. For details, see "Setting-
data subroutine L9760" on page 13.
Default value: 3150 rev/min
R24=x x= Spindle axis search distance.
This defines a search distance above the R26=z input
measuring height, which can be used to find a radial
high spot on the cutter. It is suitable for single-point
boring bars and cutters with irregular radial profiles.
Cycle time is increased using this input.
Default value: Zero (0)
