78 3 Machine Mode of Operation
3.13 Inch Mode
3.13 Inch Mode
You can operate MANUALplus in the metric or inch
system (for inch mode, see illustration to the right).
Units in inch mode:
Coordinates, lengths, path data in inches
Feed rate in inch/revolution or inch/min
Cutting speed in ft/min (feet/min)
The inch/metric setting is also evaluated for the
displays and entries in tool management and
parameters.
For accuracies for displays and entries, see the table
at right.
The metric/inch setting is selected in the parameter
"Current parameters - NC switches - Settings."
Changed metric/inch settings do not become
effective until the control is restarted.
Cycle programs
Cycle programs are always stored in the metric
system, regardless of whether they were written in
metric or inch mode. If you load a cycle program while
in inch mode, MANUALplus automatically converts
the cycle parameters to inches. The cycle parameters
are then displayed and entered in inches.
Number of decimal places Metric Inch
With coordinate data and path data: 3 4
With compensation values: 3 5
DIN programs that were written in
metric mode may only be executed in
this mode. The same applies for inch
mode. When executing a DIN program,
MANUALplus does not check whether
it was written in inch or metric mode.
Refer to your machine manual if you
want to know whether and how the
handwheel resolution can be set to
inches.
