Video: 56-Percent Productivity Increase By Reducing Chatter
The video compares a milling pass that chatters to one that is stable. Because the stable speed permits greater depth of cut, productivity increases.

Video: Basics of Thin Wall Machining
To mill thin walls in aluminum using fast light cuts, machine on alternating sides of the wall all the way down, jumping the wall with each new pass.

Video: Helical Interpolation Vs. Drilling
A machining center able to maintain precise control at high feed rates makes it practical to machine holes through helical milling as an alternative to drilling.

Applying A High Speed Machining Discipline Without The Speed
In this shop, high speed machining makes sense at 4,000 rpm. While the disciplines the shop put in place made a new 15,000-rpm profiler dramatically more productive, high speed machining would have remained valuable even if the new machine never came. Acoording to a co-owner of this shop, high speed machining has no need for speed.

High Speed Machining ... Without The Speed
Axial chip thinning is often associated with high speed machining, but this shop uses the same effect to increase metal removal rate with a standard-size end mill run on a moderate-speed machine.

High Speed Machining Without The Fast Spindle
Relying on axial chip thinning lets a larger-diameter tool realize some of the benefits of high speed machining even if the machine's spindle speed is low.
