If you are asking about material removal rate, you can use optimize feed rate, which will adjust the feed to keep the MRR within user specified limits. For example, slowing down if the tool enters a sharp corner. Note that we have cut pattern features to minimize this, such as corner rounding of the path and stepovers, and trochoidal cutting.
If you know the settings for a partular tool material, part material, and cutting type, you can save these in the machining data system, and reuse them as needed, to provide a good starting point.
If you are asking about vibration analysis, we have partners that do that.
