4.DESCRIPTION OF PARAMETERS B-64120EN/01
- 284 -
NOTE
When this parameter is set to 1, no interference
check is made in cutter compensation C.
ANM In AI contour control mode, the normal direction control function is:
0 : Disabled.
1 : Enabled.
5485
Limit imposed on the insertion of a single block for rotation about the
normal direction control axis
[Data type] 2-word
[Unit of data]
Input increment IS-A IS-B IS-C Unit
Rotation axis 0.01 0.001 0.0001 deg
[Valid data range] 1 to 99999999
When normal direction control is applied, the amount of movement
(rotation angle) on the normal direction control axis (C-axis),
calculated so that the C-axis is directed at right angles to the direction
of motion at the start point of a block, may be smaller than the value
specified in this parameter. In such a case, the C-axis movement is
not inserted before the movement (along the X-axis and Y-axis)
specified by the block. Instead, the C-axis movement is performed
together with the movement specified by the block. If the amount of
movement (rotation angle) on the C-axis is greater than or equal to the
value specified with this parameter, the C-axis movement is inserted,
and the movement specified by the block is made after the completion
of the C-axis movement.
NOTE
This parameter is enabled when the SDC
parameter (bit 0 of parameter No.5484) is set to 1.
If a value equal to or greater than 180 degrees is
specified, a C-axis movement is inserted only when
circular interpolation involving a C-axis rotation of
180 degrees or more is performed.
