It is not good practice to program radius format arcs that are nearly full circles or are semicircles or nearly semicircles because a small change in the location of the end point will produce a much larger change in the location of the center of the circle and hence the middle of the arc The magnification effect is large enough that rounding error in a number can produce out of tolerance cuts Nearly full circles are outrageously bad semicircles and nearly so are only very bad Other size arcs in the range tiny to 165 degrees or 195 to 345 degrees are OK Here is an example of a radius format command to mill an arc G17 G2 x 10 y 15 20 2 5 That means to make a clockwise as viewed from the positive Z axis circular or helical arc whose axis is parallel to the Z axis ending where X210 Y 15 and Z 5 with a radius of 20 If the starting value of Z is 5 this is an arc of a circle parallel to the XY plane otherwise it is a helical arc e Center Format Arc In the center format the coordinates of the end point of the arc in the selected plane are specified along with the offsets of the center of the arc from the current location In this format it is OK if the end point of the arc is the same as the current point It is an error if 124 when the arc is projected on the selected plane the distance from the current point to the center differs from the distance from the end point to the center by more than 0 0002 inch if inches are
