I used to believe high speed machining was just for production shops

For about 5 years I ran all my jobs at conservative feeds and speeds, thinking it'd save my tooling and avoid crashes. Then a job in Cleveland last January forced me to try a trochoidal toolpath on a 304 stainless bracket. Roughing time dropped from 8 minutes to 3 and I got double the tool life from the reduced heat. Anyone else change their mind on HSM after actually trying it on a complex part?

Oh man I was the same way. Took me crashing a brand new 3/8 endmill trying to prove HSM was a gimmick before I finally gave in and tried it on a job I was behind on.

Switched to a different chip thinning calculator and it just clicked for me.
