I have been milling a kontour on stainless plate 75x12 (all measures are mm)
Itís been working fine, but when the mill is about to finish the arc, itís not completly round.
Itís not a problem for anyone but me. Any suggestion to a solution.
My machine is a abene VHF 40 CNC and Heidenhain 155,
I also suspect that the radius compensation is calculating a bit wrong, had to move center 1mm to get the measurement correct.
