The recent posts about stress relieving (via heat or ringing like a bell) of straight edges to reduce movement got me thinking. When I read Moore's Foundations of Mechanical Accuracy, they talked about how castings that were machined with a planer mill showed less movement than castings that were machined with a rotating cutter. I have a few questions about this.
1) Does anyone know why this is?
2) Since I don't have a planer mill, are there certain speeds/feeds/DOC that work better with conventional milling to reduce movement?
Thanks,
Daniel
