Speeds And Feeds For Milling With End Mills
When choosing the right parameters to run, most people focus on the speed which relates to the machine RPM. This is a mistake! Focus on on the proper feed per tooth (FPT), and then adjust the speed. Often when a part is programmed, and is being proven out for production, the programmer will choose conservative parameters and encounter chatter.
