5.2.12 Full circle position pattern

5-188
The "Full circle position pattern" function is used to program any
number of positions that lie on a circle with a defined radius.
ShopTurn calculates the distance (angle) between the individual
positions from the number of positions. This distance is always the
same.
You can choose whether the tool should approach the next position
on a straight line or circular path. The rapid traverse feedrate for
positioning on a circular path is defined in a machine date code.
Please also refer to the machine manufacturer's instructions.
If you approach the next position in a straight line in a circumferential
groove, a collision may result.
