On my first attempt, I could not find a way to have the mill start off of the part and lead into it. so it ends ip gouging pretty bad. Also, cutting .0625 in one pass at 5100 RPM and 4 IPM proved to be way too heavy for my machine. Maybe because it is starting on the part therefor causing it to cut with the backside of the tool for a small distance. Please advise me on how to get this to lead in and what would be your suggestions for feeds, speeds, and depth of cut. I really need to get this operation running optimum.
