Cutter radius and linear profile checking
(subroutine L9865)
NOTE: This cycle can be used only if the latch mode feature of the
NC1 system is installed and operational.
This cycle is used to check the profile of ballnose cutters, cutters with
corner radii, and cutters with linear profiles. The profile is checked to
find out if it is within a specified form tolerance.
Application
The tool is retracted to the home position for safety before each
profile check unless a secondary profile check is to be performed on
the same tool (see use of inputs R02=4, R02=5, and R02=6). The
tool is positioned over the laser beam and is moved first to the
longest tool position, then to the profile start position with the spindle
rotating. The defined cutter profile is traced at the checking feedrate.
Finally, the tool is retracted out of the beam. An error flag is always
set and an alarm is optionally generated if the cutter is out of
tolerance.
If both + and – tolerance checking is specified with the R02=3 and
R02=6 inputs, the cutter is repositioned after the negative (–)
tolerance check and a reverse profile check is made along the profile.
Finally, the tool is retracted.
