Trochoidal milling is an efficient alternative to standard slot milling that uses a circular motion of an end mill to cut a slot width through a trochoid method. This high-speed machining technique produces slots in an efficient manner using an end mill moving in a circular pattern to machine the slot width.

1. Trochoidal milling is an efficient way
to cut a slot other than using the
standard slot milling method.
In trochoidal milling, an end mill is
used to machine the slot width using a
circular movement. This is called
the trochoid method. It's an efficient
way to produce slots using high-speed
machining methods.

8. Drilling - HSS 70-125 SFM
Drilling - Solid Carbide Drills - 300-450SFM
(Carbide insert drills can run a lot faster.
Anywhere from 500-1200SFM)
Turning - HSS 70-125SFM (This one is
questionable though. I don't cut with HSS at
all)
Turning - Carbide 600-1500SFM depending
on grade
Milling - HSS End mills 70-125SFM
Milling - Carbide End mills 300-1000
depending on coating.
The general rule here is carbide is superior to
HSS in most cases. If you get into softer
materials like aluminum and plastic, a HSS
endmill could do better.
