7-5 Circular Interpolation
7-43
If the start point and end point are clear and you want to perform avoidance operation along
the circular path, circular center specification is useful.
Essentially, circular center specification calculates the center point to perform complete
circular operation.
In avoidance operation, however, it is difficult to obtain the center point accurately, although
the start point and end point are clear.
If you specify the center point offset, therefore, calculate the average of two radii, namely the
radius of specified center point to start point and radius of specified center point to end point,
and recalculate the center point from that radius to perform normal circular interpolation. The
specified rotation direction is maintained.
