Acu-Rite CNC 3500i user manual Using Arc Center and EndPoint to create a circle

7.1 Explaining Basic Cycles

Using Arc Center and EndPoint to create a circle

Since the start point and end point of a circle are the same, you do not need to program an end point to create a circle. Position the tool at the required starting point before you execute the arc move.

Omit the end point parameters for X and Y.

Conversational example: Arc CCW XCenter 0 YCenter .5

G-code example: G91 G3 I0 J.5

Programming a full circle is not possible when using the XYR (Radius and EndPoint) format.
