6.4 Path contours—Cartesian coordinates
Circular path CR with defined radius
The tool moves on a circular path with the radius R.
 Coordinates of the arc end point
 Radius R
Note: The algebraic sign determines the size of the
arc!
 Direction of rotation DR
Note: The algebraic sign determines whether the arc
is concave or convex!
 Miscellaneous function M
 Feed rate F
Full circle
For a full circle, program two blocks in succession:
The end point of the first semicircle is the starting point of the second.
