I had a bad experience yesterday. I was parting a 2” aluminum bar in my lathe when all of a sudden the carbide parting tool snapped like a potato chip. Here is how I had it set up. The tool was dead on center and perpendicular to the part. My machine was at its minimum 70 rpm (23 SFM) and .0014 ipm on the cross feed. The tool was about .0375” into the work when it hogged in. Here is a picture of the tool I was using. The tool is designed to cut a maximum 5/8” radius, but I only needed to part the piece to a depth of ½” due to its hollow bore. I need to know what I did wrong. I think I’m going to hear that I probably should have used my bandsaw, but I had to ask anyway. Thanks.
