Under Development

Examined are four recent developments in cutting tool coatings: "smooth" diamond coatings, which incorporates that are nanometer-sized; a process that deposits diamond on carbide substrates via a laser; highly lubricious coatings for dry-machining operations; and a patented system for "locking" conventional coatings together.

Sizing Up Nickel

Due to the exceptional strength of IN 100, INCO 718 and other nickel-based alloys, they're difficult to machine. The author, who spent 40 years endmilling these aerospace materials, discusses their unique characteristics and methods for successfully machining them.

Clean Sweep

Equipping toolchangers with nylon abrasive-filament brushes can greatly enhance process economics and the flow of parts. Case histories of in-machine deburring operations support these contentions, and the author describes how such systems should work.
