7.3 Probing Cycles
From the Manual Data Input Mode with G-code MDI selected and the
spindle off, input:
"G153 Tn Dn En" and touch the NC Start button. Where T is the tool
number, D is roughly the diameter of the special tool (this should be
larger but not more than 0.100" (2.54 mm) larger), and E is the Z-axis
move down needed if different then the default 0.100" (2.54mm) so
that the largest part of the tool diameter comes in contact with the
edge of the probe stylus. For example, G153 T3 D3.5 E.25 and touch
the NC Start button.
The Z-axis feeds down with the spindle on, touching the top of the
probe stylus. Once the top of the probe is found, the Z-axis rapids
back up above the probe and moves over to one side of the probe
stylus. The tool then moves down the distance in E or 0.1" (2.54
mm) if E is not programmed. Then, with the spindle turning in
reverse, the canned cycle touches the side of the tool to the probe
stylus twice on opposite sides establishing the tool's diameter. The
new diameter is then stored in that tool's diameter register and
clears any value in the diameter wear register. The Z-axis then rapids
up to machine home.
The Tool Diameter has now been set and you can change to another
tool and repeat steps 1 through 3.
