(30) M164, M165 (slide hold and single block ignore OFF, ON)
These M codes are used to specify whether or not the slide hold ON and single block ON
statuses, set by the switches on the machine operation panel, are valid; in the M165 mode, if
the slide hold or single block function is set ON with the corresponding switch on the machine
operation panel, these functions are made invalid, and in the M166 mode, if the slide hold or
single block function is set ON by the corresponding switch on the machine operation panel,
these functions are made valid.
(31) M166, M167 (tailstock spindle advance/retract interlock during spindle rotation ON, OFF)
To ensure safety, the tailstock spindle cannot normally be advanced or retracted while the
spindle is rotating. However, tailstock spindle operation is permitted even while the spindle is
rotating by turning OFF the interlock.
[Supplement]
•
When the power supply is turned off or after the NC is reset, the NC is in the M166 state.
•
The state selected by these M codes is effective only for MDI and automatic operation modes.
(32) M184, M185 (chuck open/close interlock ON, OFF)
To ensure safety, the chuck cannot normally be opened or closed while the spindle is rotating.
However, chuck open/close operation is permitted even while the spindle is rotating by turning
OFF the interlock.
[Supplement]
•
When the power supply is turned off or after the NC is reset, the NC is in the M184 state.
•
The state selected by these M codes is effective only for MDI and automatic operation modes.
•
The state selected by these M codes is effective only when the door is closed.
•
The chuck interlock OFF state is effective for chuck clamp/unclamp operation specified by M
codes or external commands and it is not effective for the operation using the foot pedal and
pushbutton switches.
(33) M193, M194 (thread cutting phase matching control OFF, ON)
In the M194 mode, the phase offset amount at the thread cutting start point is calculated and
compensation is carried out at the start and end points. After the completion of the thread
cutting cycle, the M194 mode must be canceled by specifying M193 in a block without other
commands.
(34) M195, M196 (thread cutting phase matching move amount valid OFF, ON)
By specifying M196 in the block preceding the block which contains the commands to stop a
program for thread cutting phase matching, the amount of manual axis movement done in
phase matching is stored. M196 must be specified in a block without other commands.
After the completion of manual axis movement for phase matching, the M196 mode must be
canceled by specifying M195 in a block without other commands.
(35) M197 (clearing thread cutting phase matching amount)
This M code is used to clear the amount which is stored as the manual axis movement amount
for phase matching.
(36) M211, M212, M213, M214 (key-way cycle cutting mode; uni-directional, zigzag, specified
cutting amount, equally-divided cutting amount)
M211 and M212 are used to specify the cutting direction in the key-way cutting cycle; uni-
directional cutting (M211) and zigzag cutting (M212).
M213 and M214 are used to specify the infeed pattern; M213 specifies the specified cutting
amount and M214 specifies the equally-divided cutting amount.
