Does anyone have experience in using both G13 and G2 G3 for circular interpolation. I'm wondering if one is better then the other for precision holes. Does one of them produce a rounder hole ?
Thanks.

The roundness of the hole is more dependant on the mechanical condition/resolution of the machine than the G code used to create the hole. You can create a nice round hole with all G1 moves. If you need a perfect hole, then boring/reaming are the prefered methods. On my machine I can count on the hole being about 0.0005'' large when measured across the 4:00 o'clock - 10:00 o'clock vector, doesn't really matter what size the hole is. As near as I can tell this is a function of some backlash in the Y axis.

hello
@ avmcnc : if you wish to deliver a nice hole, regardless of machine condition, check this out : Vulcanaire
@ jim dawson : please, how do you measure at 4-10 ? do you use the machine probe ?
kindly !

You could have marked the origin on the figure. It saves time, and program verification becomes intuitive.
