Here is a typical result from using Machining Dynamics (tap-testing or RCSA) analysis.
Using the manufacturer's catalog chart recommendations (therefore likely what a CAM system would select) the tool chattered. The normal response would be to slow down. By tap-testing the tool assembly in the machine, generating a stability lobe diagram and Dashboard, we revealed a much faster stable speed. Using chip thinning we were also able to increase the feed rate a bit. Took all of five minutes and ran stable the first time.
We maintained the same width and depth of cut in this application but they too could potentially be optimized for greater productivity increases. Now the CAM system can optimize the tool path using the best possible speeds at the maximum stable engagement and you are really off to the races.
