Contents
Set the return amount for G73 (step cycle).
Set the return amount for G83 (deep hole drilling
cycle).
Set the screw cut up amount for G76‚ 78 (thread
cutting cycle).
Set the screw cut up angle for G76‚ 78 (thread
cutting cycle).
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.
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.
Set up return length m at a G84/G74 pecking tap
cycle.
(Note) Set 0 to specify a usual tap cycle.
Contents
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.
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.
If the set value is smaller than
θ
θ
, the speed goes down to
optimize the corner.
(Note) If "0" is set, it will be handled as 5 degrees.
The standard setting value is "0".
