202 7 Programming: Canned Cycles, sub-programs
7.3 Probing Cycles
Field Code Description
Tool# T Tool number. (Required)
With only the T cycle parameter present,
the canned cycle does not step over half
the tool's diameter but comes straight
down measuring the tool length and storing
it in the tool register.
EstDiam D This is the rough diameter of the tool. This
should be within 0.04" (1.0 mm). (Optional)
If the D cycle parameter is present, the tool
steps over half of its diameter, the spindle
turns on in reverse and then the canned
cycle measures the tool's length.
A negative D value is for a left-handed tool
and causes the spindle to come on forward
instead of reverse.
For on center length measurement, do not
give a D cycle parameter.
MeasType Q This option specifies to measure length,
diameter, or both and the appropriate tool
registers are updated. (Optional)
[Default: Q1]
Q0 Measure the diameter only
Q1 Measure the length only
Q2 Measure both length and diameter
If Q is not set, the cycle measures the tool
length only.
If Q0 or Q2 are programmed, you must also
have a D cycle parameter or the control
displays an error message.
