TIL my whole approach to facing cuts was backwards

I was finishing a batch of 304 stainless parts for a shop in Tacoma, and my surface finish kept looking rough. My boss, Frank, walked by and just said 'your tool is climbing when it should be conventional.' I'd been running my facing ops with climb milling for years thinking it was better. Switched it on the Haas, and the finish went from a 125 to a 32 in one pass. Anyone else get stuck on a 'better' method that was actually worse?

Been there, done that.

Wait, climb milling on aluminum? That's how you break an end mill. You have to go conventional with aluminum to clear the chips, or it just welds itself to the tool.

Frank's right for stainless, but that's not a universal rule. Climb milling is usually better for aluminum and to save your machine. It just depends on the material and what you're doing.
