you cannot machine a circle using g01 unless you break your circle into very small segments to make it smooth enough. use a g02 or g03(circular interpolation) command with R address for specified radius for semi-circles and I,J,K addresses for full circles. you can also use the I,J,K addresses for semi-circles but that could be a little confusing for a newbie.
