16.1 Tool calibration
It is used to calibrate the tool of the spindle in length or in radius. The
following operations are possible with this cycle.
• Calibrate the length of a tool.
• Measure the length wear of a tool.
• Calibrate the radius of a tool.
• Measure the radius wear of a tool.
• Calibrate the radius and length of a tool.
• Measure the radius wear and length wear of a tool.
It requires a table-top probe, installed in a fixed position of the machine
and with its sides parallel to the X, Y and Z axes.
If it is the first time that the tool is being calibrated, it is recommended
to enter its approximate dimensions in the tool offset table. Once the
cycle has concluded, the tool table is updated with the data
corresponding to the tool offset that is currently selected.
Programming
The programming format for this cycle is:
#PROBE 1 B I J F K L D S M C N X U Y V Z W
Depending on the operation to be carried out, it will not be necessary
to define all the parameters.
Parameters X, U, Y, V, Z, W
They define the probe position. They are optional parameters that
usually need not be defined.
• Parameters X-Y-Z refer to the minimum coordinates of the probe
on the first axis, second axis and on the axis perpendicular to the
plane respectively.
• Parameters U-V-W refer to the maximum coordinates of the probe
on the first axis, second axis and on the axis perpendicular to the
plane respectively.
In certain machines, due to lack of repeatability in the mechanical
positioning of the probe, the probe must be calibrated again before
each calibration.
Instead of re-defining the machine parameters every time the probe
is calibrated, those coordinates may be indicated in these parameters.
The CNC does not modify the machine parameters and takes into
account the coordinates indicated in X, U, Y, V, Z, W only during this
calibration.
If any of the X, U, Y, V, Z, W fields is left out, the CNC takes the value
assigned to the corresponding machine parameter.
