Common misperceptions about lean manufacturing and automation systems lead many manufacturing managers to dismiss the use of automation in a lean setting.

When a tool breaks during a machining operation, the part being processed is often destroyed, and sometimes the machine is damaged. Aerospace parts are often complex shapes, manufactured from exotic materials that require prolonged machining cycle times. Therefore, a scrapped part is a significant loss in raw materials and value-added machining.
Highly realistic 3-D simulation software can greatly improve manufacturing processes, lending sophisticated visualization tools that help increase manufacturing productivity and product quality.
When first introduced in the late 1970s, cutting tool coatings—especially titanium nitride (TiN)—were embraced by tool manufacturers for their ability to extend tool life. As workforce materials have expanded from conventional ferrous and nonferrous metals to exotic alloys, composites, ceramics, and others, coatings have likewise progressed and, thanks to new formulations and deposition methods, are extending cutting tool capabilities as well as tool life.
Secure, accurate workholding sets the stage for consistent machining productivity. Depending on the parts and processes involved, workholding can be as simple and temporary as a plain vise or clamp or as complex and permanent as a machined and fabricated fixture that is custom-designed to hold a unique part.
The growing need for nano and micro components in the medical industries is challenging manufacturers to continually improve upon their manufacturing processes and take a scientific approach to injection molding and tooling.
One of the great benefits of solid round cutting tools is the ability to resharpen them after heavy use. Done right it’s like having a cat with nine lives: Dull…then like new. Dull again…and like new again. And since the cost to recondition solid tools is generally lower than the cost to replace them, there’s an economic benefit. The question then becomes what’s the best way to achieve the greatest possible benefit?
Makers of machine tools used to produce gears are looking to the 2018 edition of IMTS to demonstrate how they’re meeting customer demands.
If John Winter of toolmaker Sandvik Coromant (Fair Lawn, NJ) were to start his own machine shop, all of his machines would be equipped for through-spindle coolant (TSC).
Cryogenics offer an alternative to traditional liquid coolants when conventional cooling methods can’t or don’t do the job well enough.
