Circular path CR with defined radius
The tool moves on a circular path with the radius R.
ú
Enter the coordinates of the arc end point.
ú
Radius R
Note: The algebraic sign determines the size of the
arc.
ú
Direction of rotation DR
Note: The algebraic sign determines whether the arc
is concave or convex.
Further entries, if necessary:

Miscellaneous function M
Full circle
For a full circle, program two CR blocks in succession:
The end point of the first semicircle is the starting point of the
second. The end point of the second semicircle is the starting point
of the first. See figure at upper right.
Central angle CCA and arc radius R
The starting and end points on the contour can be connected with
four arcs of the same radius:
Smaller arc: CCA<180°
Enter the radius with a positive sign R>0
Larger arc: CCA>180°
Enter the radius with a negative sign R<0
The direction of rotation determines whether the arc is curving
outward (convex) or curving inward (concave):
Convex: Direction of rotation DR– (with radius compensation RL)
Concave: Direction of rotation DR+ (with radius compensation RL)
Example NC blocks
See figures at middle and lower right.
