<FIXED C.> (Fixed cycle)
# Item Contents Setting range (unit)
8012 G73 n
(For M system only)
Set the return amount for G73 (step cycle). 0 to 99999.999 (mm)
8013 G83 n Set the return amount for G83 (deep hole drilling
cycle).
0 to 99999.999 (mm)
8014 CDZ-VALE
(For L system only)
Set the screw cut up amount for G76‚ 78 (thread
cutting cycle).
0 to 127
(0.1 lead)
8015 CDZ-ANGLE
(For L system only)
Set the screw cut up angle for G76‚ 78 (thread
cutting cycle).
0 to 89 (degrees)
8016 G71 MINIMUM
(For L system only)
Set the minimum cut amount for the final cutting in
G71‚ 72 (rough cutting cycle).
If the final cutting amount is smaller than this value‚
the final cut will not be performed.
0 to 99.999 (mm)
8017 DELTA-D
(For L system only)
Set the change amount to the command cut amount
D for G71‚ 72 (rough cutting cycle).
Each cut amount will be the value obtained by
adding or subtracting this value from command D‚
and thus‚ the amount can be changed each cut.
0 to 99.999 (mm)
8018 G84/G74 return
(For M system only)
Set up return length m at a G84/G74 pecking tap
cycle.
(Note) Set 0 to specify a usual tap cycle.
0 to 99.999 (mm)
<PRECISION> (High precision control)
# Item Contents Setting range (unit)
8019 R COMP Set up a compensation factor for reducing a control
error in the reduction of a corner roundness and
arch radius.
Indicates a maximum control error (mm) in
parentheses.
The larger the setup value, the smaller the
theoretical error will be. However, since the speed
at the corner goes down, the cycle time is extended.
0 to 99 (%)
8020 DCC ANGLE Set up the minimum value of an angle (external
angle) that should be assumed to be a corner.
When an inter-block angle (external angle) in high-
precision mode is larger than the set value, it is
determined as a corner and the speed goes down to
sharpen the edge.
(Note) If “0” is set, it will be handled as 5 degrees.
The standard setting value is “0”.
0 to 30 (degrees)
0: The angle will be 5
degrees.
θ
If the set value is smaller than
θ
, the speed goes down to
optimize the corner.
