Result
Circle inside machining takes place.
With continuous traversing of the X axis using the plus traversing key, a counter-clockwise (G2)
circular movement can be initiated with a radius of 10 mm about the center point of the circle
(10, 20).
With the traversing of the Y axis, the circle radius can be changed between 0.02 and 19.98.
