Caught a tool pull-out on the last pass on a 4140 shaft in Dayton

I was roughing a 3 inch diameter shaft on the lathe last Wednesday when the insert chipped and the tool pushed off about 0.015 deep on the finish pass. Rather than scrap the part, I dropped the feed to 0.006 and ran two lighter spring passes, and it cleaned up fine. Curious what feed and depth you all run when a shaft starts pushing like that.
