5.1 Straight or circular path movements
To program a circle or arc with a known radius in Cartesian
coordinates, use the "Circle radius" function.
The tool traverses a circular arc with the programmed radius from its
current position to the programmed target position at the machining
feedrate. The position of the circle center point is calculated by
ShopTurn.
You can choose to traverse the arc in the clockwise or anticlockwise
direction. Depending on the direction of rotation, there are two options
for approaching the target position from the current position via an arc
of the specified radius. You can select the arc of your choice by
entering a positive or a negative sign for the radius.
