Need Help!- K and I

[teamus]

I haven't used this in a long time but I'm starting a job that has older machines.

When generating a radius, how do the I and K factor in? I remember something about measuring from the center of the radius at the begining of the cut.

Can you give me an example??

Thanks!!

G02 Z# X# K# I#

K is Z distance to arc center
I is X distance to arc center
Z is z end of arc
X is X end of arc

machine must be at start of arc when G02 or G03 is issued.

Note some machine have absolute arc centers, most have relative arc centers
