14. ACCURACY COMPENSATION
FUNCTION
NC FUNCTION
83
The errors caused by machine position, as pitch error of the feed screw,
can be compensated. This function is for better machining precision.
As the offset data are stored in the memory as parameters, compensations
of dogs and settings can be omitted. Offset intervals are set constant by
parameters (per axis). Total offset points are:
Total offset points = 128 × controlled axes.
Optional distribution to each axis can be done by parameter setting. As
each position:
Offset pulse = (-7 to +7) x (magnification)
Where Offset pulse unit is the same as detection unit
Magnification: 0 to 100 times, set by parameter (per axis)
This function is used to compensate lost motions proper to the machine
system. Offset amounts come in a range of 0 to "9999 pulses per axis,
and is set as parameters in detection unit.
Parameters and pitch errors data can be set by programs. therefore,
following uses can be done example.
D Parameter setting such as pitch errors compensation data, etc. when
the attachment is replaced.
D Parameters such as max. cutting speed and cutting feed time constant
can be changed according to the machining conditions.
