This means that they set modes or prepare the machine for various actions. Circular interpolation requires five pieces of information’s; an endpoint, a feed rate, a center, a radius, and a direction of movement.

How do I plot a circular arc with given two endpoints and radius?

h contains arc () function which draws an arc with center at (x, y) and given radius.Set the interpolation mode to “circular/helical, clockwise”. Going by the sizes you gave, it should be 50,50 for your inner arc and 100,100 for the outer. This will depend on what arc plane has been selected. You can also use the arc length calculator to find the central angle or the circle’s radius. Circular interpolation is a motion of tool in circle.
