I have a problem to solve.
If i mill a corcle R=20 with tool r=20 and use stepover 100%
then my tool will make (R+r)/R = (20+20)/20 = 200% feed speed on outer edge of the tool.
how can i compensate this in my post processor so that it calculates the reduction of speed in circular segments because of this?
I found a compensation factor in the roughing cycle to use when more and less material is cut but it does not handle the problem with increased speed in outer edges.
Our tool provider has informed us that this was the probable cause of several tool faliours for us.

Been there, done that, bought the t-shirt.
But this speed calculation in curves is only applied in profiling not in roughing.
Its a good start for finishing. But how does the rest of all edgecam users cope with this?
Are people not using more then 10% of cutdata that are given by the supplier?
If you take a 63mm end mill and run into an open pocket 70 wide, leaving 0.5mm offset. then the tool might (depending of shape) do a circular tun in the far end. R=3mm this would make the f go up to (r+R)/r = (31.5+3)/3 = 11.5 times normal f = my tool went to a warmer place down under.
