7.PMC CUSTOMIZING TOOLS USER PROGRAM B-63343EN/02
- 106 -
• Set 0 to R961 when line/circle cutting are not necessary.
R962 to R974 may have any value.
• R979 (information of setting change) is a signal to inform
CNC that the data for line/circle cutting were changed.
i) Set data for R961 - R974
ii) Set "0" to R979 after setting the above data
iii) CNC begins to read data
iv) CNC set "1" to R979 after reading
• If some of data were changed during executing a cutting by
guidance handwheel , all the data must be set again.
As described in 5.4 "User Program s for Guidance
Cutting", the all procedure for the above data
signals are already prepared as the standard
custom macro program. So, MTB needs not to
make them by themselves, if they need not to
2) Synchronous feed with a guidance handwheel
When the above signal is "1", machine motions are controlled as
During automatic operation of machining program, the feedrate
of line (G01) or circle (G02/G03) motions is not controlled by
inputted feedrate in a program, but a guidance handwheel
The tangential speed of motion is controlled by synchronizing
with a guidance handwheel rotation.
During running in dry run mode or machining
simulation, The above synchronous feed function
cannot be used. So, when the signal "DRN" is "1",
set the above signal "HDLF" to "0" always.
3) Selecting moving axis
When non-zero value is set into the R961 described in 1), by
using the following signals, moving axis by handwheel can be
selected. These signals are prepared for each handwheel, and are
code signal data made up from 4 signals, A/B/C/D.
The number in a name of each signals means the handwheel
