NIZ Smoothing in rigid tapping is:
0 : Not performed.
1 : Performed.
TDR Cutting time constant in rigid tapping
0 : Uses a same parameter during cutting and extraction (Parameter Nos.
5261 through 5264)
1 : Not use a same parameter during cutting and extraction
Parameter Nos. 5261 to 5264: Time constant during cutting
Parameter Nos. 5271 to 5274: Time constant during extraction
OVU The increment unit of the override parameter (No.5211) for tool rigid
tapping extraction is:
0 :
1%
1 : 10%
OV3 The spindle speed for tool extraction is specified by program. Overriding
based on this spindle speed is:
0 : Disabled.
1 : Enabled.

NOTE
When this parameter is set, the power must be turned off
before operation is continued.
[Data type] Bit
ORI When rigid tapping is started:
0 : Spindle orientation is not performed.
1 : Spindle orientation is performed.

REF Feed forward during movement from the initial point to point R in rigid
tapping is:
0 : Disabled.
1 : Enabled.
When this parameter is set, the following function is also enabled:
D When rigid tapping is specified in look–ahead control mode, the
system automatically exits from look–ahead control mode and
executes rigid tapping. After termination of rigid tapping, the system
automatically returns to look–ahead control mode.
