How to compile circular interpolation program with lathe programming software?

1, circular interpolation instruction is divided into clockwise circular interpolation instruction G02 and counterclockwise circular interpolation instruction G03. Judging the positive and negative directions of arc interpolation: looking along the negative direction (-Y) of the vertical coordinate axis of the plane where the arc is located (such as XZ plane), it is G02 clockwise and G03 counterclockwise.

2. When machining an arc on a lathe, not only should G02/G03 be used to point out the counterclockwise direction of the arc, but also X(U) and z(W) should be used to specify the coordinates of the end point of the arc and the center position of the arc.

3. When using absolute value programming, the coordinates of the arc end point are the coordinates of the arc end point in the workpiece coordinate system, which are expressed by X and Z. When using incremental value programming, the coordinates of the arc end point are the incremental values of the arc end point relative to the arc start point, which are expressed by U and W..

4. When the radius r is used to specify the position of the center of the circle, because there are two arcs from the starting point to the end point of the arc with the same radius r, in order to distinguish them, when the central angle α≤ 1800 is specified, it is represented by "+R", and α >: when 1800, it is represented by "-R".

5. The center coordinates I and K are the component vectors of the vector from the starting point of the arc to the center of the arc on the X and Z coordinate axes, respectively.
