Hi Folks,
Tormach 770, using the module 25mm endmill with tormach steel cutting inserts. I am working on dialing the program in for surface finish with poor results. I seem to have chatter maybe? it sounds ok when cutting, loud but no squealing. A-2 material, .060" DOC, .1" stepover, 1600 RPM, 18 IPM. Image attached, Thoughts?
