Smaller when conventional exact when climb milling

(ray) #1

Does any one know why my circles are "0.020 smaller when I use conventional milling and exact when I use climb milling? Happens in both X and Y. I’m using aspire.

The machine or the endmill are getting pulled into the cut when using conventional milling.

Best way to avoid this is to leave a roughing clearance >chipload and then make a finishing pass.
