- Reset
A reset performed in the interpolation type rigid tapping mode cancels
the interpolation type rigid tapping mode (Cs contouring control
mode) and places the spindle in the normal rotation control mode.
However, bit 6 (CLR) of parameter No. 3402:
0: Does not cancel the G84 (G74) mode.
1: Cancels the G84 (G74) mode.
- Feed hold and single block
In the G84 (G74) mode, the feed hold and single block functions are
disabled when bit 6 (FHD) of parameter No. 5200 is set to 0. When
the bit is set to 1, the feed hold and single block functions are enabled.
If feed hold is applied between operation 3 and operation 5, the feed
hold lamp is turned on immediately, but the tool performs up to
operation 6 before the tool stops.
The single block stop points are the end points of operations 1, 2, and
6 when bit 6 (FHD) of parameter No. 5200 is set to 0. When bit 6
(FHD) of parameter No. 5200 is set to 1, the tool stops after
completion of each operation.
- Backlash compensation
In interpolation type rigid tapping mode, the backlash is compensated
for the lost motion at forward and reverse spindle rotations. Set it
using parameter No. 5321 to No 5324. The normal backlash
compensation is inserted on the drilling axis.
- C-axis clamp/unclamp
T
An M code can be specified to clamp/unclamp the C-axis
mechanically in rigid tapping. By adding an M code for clamping to a
block specifying G84/G88, both M codes are output. A description
of timing is provided later.
An M code for clamping is to be set in parameter No. 5110. An M
code for unclamping assumes the value set in parameter No. 5110 plus
1.
No.5110
0 Other than 0
No M code is output. Value set in parameter No. 5110 + 1
