I finally saw how a master machinist squared up a block of 304 stainless at a job shop in Toledo

That one demo back in 2019 at Anderson's Precision Parts showed me I had been wasting time on roughing passes for years, has anyone else had a moment like that where you realized your whole g code approach was outdated?

Anderson's Precision Parts... man, those guys are wizards. I remember watching a video online of a guy taking a 1/2 inch doc on a 304 block with a 3/4 rougher and I almost spit out my coffee. I had been babying my toolpaths for years with tiny passes and constant pecking because I was scared of chipping. That video showed me taking a full 3/4 depth of cut in 316 with a 1/2 inch endmill and no coolant at all, just spot on feeds and speeds. It completely blew my mind. I changed my whole post processor that afternoon.

Hard disagree. Baby steps saved my collets and my sanity more than once.

Adamthompson, that Anderson's shop is legit, right? I saw that same demo a few years back and it changed how I think about roughing completely. Before that, I was stuck in the same mindset, running light cuts and slow feeds because I thought that was the only safe way. Watching them take full depth cuts in 304 without any drama made me realize I was just scared, not smart. It took some testing on my own machine, but once I adjusted my feeds and speeds to match that approach, my cycle times dropped like crazy. Hard to argue with real results like that.
