(PDF) Grinding in Ball Mills: Modeling and Process Control

In most grinding machines, operators input depth of cut, feedrates, plunge speeds, etc. The concept of inputting the material removal rate – and allowing the machine to choose a corresponding feedrate – is better. This can be of enormous benefit in reducing cycle times, avoiding excessive wheel wear, and achieving more consistent grinding.
