Fig. 14.2 is an excellent illustration, would be a nice addition to the Mach manual.
You explained it quite well in the other post as well.
 
I guess Mach just needs to "catch up" with the manual.
Thanks for looking at it Graham.........again.

Thanks Graham. I take it though that the illustration does not represent a top down view on a front tool post and that I must interpret this in reverse.

I'm not giving up my dreams yet but I got work to turn so in the meantime I guess  I should get out my calculator and start programing.

I am also using mach for a 2 turning machines, so it would be much appreciated if the radius compensation would be included.

Is there any way that a user can help to implement that ?

Thanks
