Just reading through this post on cutter comp, Graham says g41 or g42 on a lead in (g1 or g2-g3)-( Correct me if I'm wrong,) but I was always taught
Not to use cc on a lead in arc. Always g41 or g42 on a linar  (g1)   move first, than the arc.   example-g41 x0y0 than  g2 or g3  for your blend. Then when you arc out for
blend-g40 with no g1. I always make my lead in g1 no less than my cutter di.
 Thats the way I always do it.

Hi Ed,

your comments are true, but it also depends on the control some need 90 degree only approach others can work out vectoring some will apply the the cc during the rapid to position.  If you read through the G-code examples you will find that the samples are code as you were taught.  CC can also be applied on a single arc lead in.

Thanks Graham,
 So, if cc works in a rapid to position, this would cut down the machining time, which is a good thing.
I'll have to try more variables,

I am sure you already have, I mean being married to Bretts sister must hold vast quantities of variables ;D
