One PVD coating technique with certain advantages
Most PVD coaters use cathodic-arc evaporation, in which an electric arc vaporizes the coating material from a cathode. The vaporized material condenses on the tool, resulting in a wear-resistant coating imbued with whatever qualities the coater is looking to impart to the tool.

Which is better: dry or wet machining?
Throughout the sometimes-contentious world of machining, the debate rages about whether to apply flood coolant or cut dry. As in many areas of machining, the choice is not easy and requires careful and informed consideration. To further complicate the decision, minimum-quantity lubrication (MQL) can be a successful compromise that provides an efficient and effective answer to the troublesome question.
Single-point thread programming can be fun and easy

Single-point thread programming can be fun and easy
Before CNC lathes, single-point threading was a pain in the neck. Fast reflexes were needed to engage an engine lathe's lead-screw dial at precisely the right time and disengage it before crashing into the shoulder. Around the time of the U.S. Bicentennial celebration, tape-operated lathes made all of this headache obsolete.

A strong, but light-load-bearing metal nano-composite
Talk about composites in most machine shops usually refers to carbon-fiber material, though "composites" may refer to a variety of mixed materials going back to the mud-and-straw structures made in ancient times. The latest example: A new metal nanocomposite composed of magnesium infused with a dense and even dispersal of ceramic-silicon-carbide nanoparticles.

Becoming familiar with CAD: General Industry Coverage
CNC machining takes a blend of computer skills and machining skills. Some competent machinists, especially old-timers, lack the computer skills needed to go from print to part using CNC machines. I previously lacked the computer skills, but couldn't tolerate not having complete control of the jobs I was running.
