J0 (calibration). L0 (the tool is not rejected due to wear). C0

Measure or calibrate the tool length on its tip.
It may be carried out either with the spindle stopped or turning the in
the programmed direction (opposite to the cutting direction) It is
useful for calibrating tools with several cutting edges or tools whose
diameter is greater than the probe's probing surface.
Calibration format:
(PROBE 1, B, I1 , F, J0, D, S, N, X, U, Y, V, Z, W )
Format for wear measurement:
(PROBE 1, B, I1 , F, J1, L, D, S, C, N, X, U, Y, V, Z, W )
Parameters J, L, D, S, C, N are optional. If not programmed, the
following values are assumed:
J0 (calibration). L0 (the tool is not rejected due to wear). D= tool
radius (probing is carried out on the tip). S0 (spindle stopped). C0
(interrupts the execution for the user to select another tool). N0 (the
cutting edges are not measured separately).
Once the calibration cycle has ended
It updates global arithmetic parameter P299 and assigns the
measured length to the tool offset selected in the tool offset table.
If the dimension of each cutting edge was requested, "N" parameter,
the measured values are assigned to global arithmetic parameters
P271 and on.
Once the wear measuring cycle has ended
When using tool life monitoring, it compares the measured value
with the theoretical length assigned in the table.
B Safety distance, with positive value greater than "0".
I1 Measure or calibrate the tool length on its tip.
F Probing feedrate, in mm/min. or in inches/min.
J J0 = Calibration; J1 = Measurement
L
Maximum length wear permitted (with J1 and when using tool
life monitoring).
D
Radius or distance referred to the tool shaft being probed. If not
programmed, it is done on the tip
S
Tool turning speed and direction. Select the opposite of the
cutting direction (positive sign if M3 and negative if M4)
With S0, calibration with spindle stopped.
C
Behavior when exceeding the maximum wear allowed (L other
than 0)
C0 = Interrupts the execution for the user to select another tool.
C1 = The cycle replaces the tool with another one of the same
family.
N
Number of cutting edges to be measured. If N0, one
measurement.
To measure each cutting edge when the spindle has feedback
and s.m.p. M19TYPE (P43) =1.
X...W Optional
P299 = measured length - previous length (L+K)
L = measured length
