ANM CTI SDC
[Data type] Bit
SDC In normal direction control:
0 : A C-axis movement is automatically inserted between blocks so
that the C-axis is directed at right angles to the direction of
motion at the start point of each block. (After movement on the
C-axis, movement (along the X-axis and Y-axis) specified by the
block is performed.)
1 : If the amount of C-axis movement is smaller than the value set in
parameter
No.5485, a C-axis movement is not inserted before a block. Instead, it
is performed together with movement along the X-axis and Y-axis.
CTI If such an arc that the vector from the center of the arc to a start point
rotates in the reverse direction after cutter compensation is specified
during normal direction control in the cutter compensation C mode:
0 : P/S 041 alarm is issued.
1 : The command is executed.
If this parameter is set to 1, and such an arc that the vector from the
center of the arc to a start point rotates in the reverse direction after
cutter compensation is specified during normal direction control in the
cutter compensation C mode (see the tool path from (4) to (5) in the
figure below), the tool is controlled so that the tool faces in the
direction at right angles to the move direction (programmed path)
before cutter compensation (see the tool path from (2) to (3) in the
figure below).
Thus, as shown by the programmed path from (4) to (5) in the figure
below, the inside of an arc where the radius of the workpiece is
smaller than the compensation value of the tool can be cut.
