Unlike its name, the use of shrink-fit tooling is expanding. A shrink-fit toolholder starts with a slightly undersize bore that is heated to enlarge the inner diameter enough to accept a cutting tool and then grip the cutter as it cools and contracts.
The history of cutting tools goes back a ways—a long, long way. Our prehistoric ancestors were pretty good at making stone tools, and the technology has improved from there. I saw how much on a February visit to the Deutsches Museum in Munich, which has an exhibit on the history of machining.
Not long ago, the mention of workholding might call to mind the traditional vise or three-jaw chuck. The integral nature of proper fixturing to successful machining has forever changed that paradigm and made workholding as critical to the manufacturing process as any of the machines or systems of which it is a part.
When weighing the choice of replaceable-tip mills and drills or solid-carbide tools, consider this succinct statement from one industry expert: carbide equals cost.
In this podcast discussion with Rick Schultz of FANUC America and Bruce Morey, Senior Technical Editor for Manufacturing Engineering Magazine, current practices in aerospace machining is dissected. Many shops today stick with the tried and true to reduce risk to schedule and profit, but that tried and true is stuck in the 1980s and 1990s. Rick discusses practical ways to get the most out of 21st century machining technology, by programming for the part and not the machine.

Alicat Scientific is an ISO 9001 manufacturer of mass flow meters, mass flow controllers and pressure controllers for gases and liquids. Based in Tucson, Ariz., Alicat has been designing and manufacturing precision instruments since its inception in 1991.
Horizontal machining center technology—a long-time mainstay of OEMs and Tier One contract manufacturers—has morphed into space efficient, versatile machining platforms that any high-mix job shop can benefit from.
Like most of the digital architecture of manufacturing, computer numerical controllers (CNCs) have advanced rapidly in recent years, producing far more processing speed and implementing advanced algorithms, while at the same time offering simpler, more intuitive user interfaces.
Cutting tool consumption in January 2020 rose 5 percent compared with December 2019, according to the U.S. Cutting Tool Institute and AMT - The Association for Manufacturing Technology.
