Calibrating the NC1

Calibrating the NC1 (subroutine L9861)

Subroutine L9861 is used for regular calibration of the NC1 system. It
should also be used after the laser beam has been aligned with the
Beam alignment cycle. The Calibration cycle is used for the following
tasks:
Accurately calibrating the positions of the beam in the X, Y and Z-
n
axes.
Compensating for variations in the spindle axis and radial-
n
measuring axis due to temperature changes in the machine tool.
Temperature compensation is described in "Temperature
compensation tracking (subroutine L9861)" on page 79.
CAUTION: Before running this cycle or any other cycle
!
(except the Beam alignment subroutine L9860), nominal
calibration data must be loaded.
This data can be entered automatically using the Beam alignment
subroutine L9860, with the R02=1 input. Alternatively, approximate
data can be entered manually (for details, see "Parameter store for
calibration data" on page 12).
Calibration tool required
This cycle requires a calibration tool to be loaded in the spindle of the
machine and the tool number (T) must be active.
Ideally, this should be a solid, flat-bottomed, cylinder-type tool having
minimal runout. The exact setting length and diameter of this tool
must be known.
