Programming A Circle With Known Radius - Siemens SINUMERIK 828D Operating Manual

Programming a circle with known radius

To program a circle or arc with a known radius, use the "Circle radius" function.
The tool traverses a circular arc with the programmed radius from its actual position to the
programmed target position at the machining feedrate. To do this, the system calculates the
position of the circle center point.
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.
