Diameter programming
Diameter programming is set via machine data:
MD20100 $MC_DIAMETER_AX_DEF = "X" ; Transverse axis is x
MD20150 $MC_GCODE_RESET_VALUES[28] = 2 ; DIAMON
MD20360 $MC_TOOL_PARAMETER_DEF_MASK
= 'B1001010'
; Tool length, frames and
; Actual value in the diameter
The following is to be taken into account:
● Axis positions in the MCS are not included as diameter value.
● The calculated tool lengths and frame components do not depend on the active G code
DIAMON or DIAMOF.
● The measured positions and setpoint positions are read and written depending on
DIAMON.
● The translations in the frames are calculated as a diameter in the transverse axis.
Arithmetic and display precision
Position values in mm, inches or degrees are accurately calculated and displayed to six
decimal places.
7.5.2.6 Diagnostics
The following diagnostic options exists for the measurement interface:
● If the file /_N_MPF_DIR/_N_MEAS_DUMP_MPF is available, a log is written in the file that
should enable the reproduction of the problem.
● The logging is started by creating a blank file having the filename _N_MEAS_DUMP_MPF
in the /_N_MPF_DIR directory.
● The content of the file is preserved till it is deleted with $AC_MEAS_VALID = 0.
For runtime reasons, the trace should be activated only if a problem is detected.
