SINO SDS2-2MS - Function Overview and Parameters

Circular arc equally Dividing Function(PCD Function)
This function may be used to divide a circular arc equally, for example in
the processing of drilling holes distributed uniformly
on a flange. After selecting this function, the
message window will prompt for various parameters
to be defined for the operator.
The following are parameter to be defined.
1. The position of the circle center.
The position of the circle center (CT POS) means
the position of the circle center with respect to the
center of the tool just after tool setting and clearing,
such as the position of Point O with respect to
Point A in Fig. (A).
2. Diameter(DIA): The Diameter of the circle to
be divided equally.
3. The number of holes(NUMBER):
The number of holes equally dividing the circle.For the example shown in
Fig. (B), 5 points from point 1 to Point 5 must used to divide the arc from 0°
to 180° into 4 equal sections. So, 9 points must be used to divide the whole
