3D PROBING (Cycle 444) 16.4
Please note while programming:
In order to achieve exact results from the touch
probe being used, a 3-D calibration should be
conducted before probing with Cycle 444. Software
option 92 3D-ToolComp is required for 3-D
calibration.
Cycle 444 generates a measuring log in HTML
format.
An error message is output if a mirroring (Cycle 8)
or scaling (Cycle 11, 26) is active before Cycle 444 is
run.
Depending on the setting of the parameter
CfgPresetSettings, it is checked during probing
whether the positions of the rotary axes match the
tilting angles (3-D ROT). The TNC displays an error
message if that is not the case.
If your machine is equipped with a controlled
spindle, you should activate the angle tracking in the
touch probe table
(TRACK
column). This generally
increases the accuracy of measurements with a 3-D
touch probe.
Cycle 444 references all coordinates to the input
system.
The TNC writes the measured values to return
parameters (see "Cycle run", page 425).
The workpiece status good/rework/scrap is set via
Q parameter Q^83, independent of parameter Q309
(see "Cycle run", page 425).
