Improvement in the
tool measuring
cycle PROBE1
The programming cycle for the PROBE1 cycle is:
(PROBE 1, B, I, F, J, K, L, C, D, E, S, M, C, N, X, U, Y, V, Z, W)
Parameters X, U, Y, V, Z, W
They are optional parameters that are not usually necessary.
On certain machines, due to lack of mechanical positioning
repeatability of the probe's, the probe must be calibrated before
each tool calibration.
Instead of redefining machine parameters PRBXMIN, PRBXMAX,
PRBYMIN, PRBYMAX, PRBZMAX, PRBZMIN every time the probe
is calibrated, those coordinates may be indicated in variables X, U,
Y, V, Z, W, respectively.
The CNC does not modify the machine parameters and only takes
into account the coordinates indicated in X, U, Y, V, Z, W during this
calibration.
If any of the X, U, Y, V, Z is left out, the CNC takes the value
assigned to the corresponding machine parameter.
31.1 Measure or calibrate the tool length.
Measure or calibrate the tool length on its shaft.
It is carried out with the spindle stopped. It is useful for drilling tools,
ball end-mills, or tools whose diameter is smaller than the probe's
probing surface.
Calibration format:
(PROBE 1, B, I0 , F, J0, X, U, Y, V, Z, W )
Format for wear measurement:
(PROBE 1, B, I0 , F, J1, L, C, X, U, Y, V, Z, W )
Parameters J, L, C are optional. If not programmed, the following
values are assumed:
Parameter "I" defines where the
measurement or calibration will be
carried out:
I0 On the tool shaft.
I1 On the tool tip.
If not programmed, the canned cycle
takes the value I0 (on the tool shaft).
B Safety distance, with positive value greater than "0".
I0 Measure or calibrate the tool length on its shaft.
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).
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.
