Very sm radius on Mori Dura center

[tonyjohnson]

I have a large loop radius happen when my MSX501 Fanuc control sees a very small G02 or G03 radius of say less than .001.Is this a parameter issue I can change?Changing the post to output only points works for 3D work but a bad finish occurs when interpolating bores.

I've had smaller radiuses (.0002) on many mori's with no problems. Are you usign R's or IJK"s. It's likely not a machine problem. IJK is my first choice and also try breaking arcs into quadrants in .cmd and see if that helps.

I have a SV50 mori with no problems with the same gcode.My MC reseller thought a parameter change might be needed.Im using I and Js.We tracked the error to a radius less than .001.The control takes a backward route when it sees the small radius.

Why would you get a .001 radius when doing bores?Are you using an arc as the geometry or is this from your lead In/Outs?
