Machining

Real-time measurements during metalcutting can offer significant insight into machine tool performance. The parameters to be measured include position, velocity and acceleration of the axes; cutting force; sound; temperature; and acoustic emission, which is not the same as sound, but rather a high-frequency, structure-borne vibration.

One fond memory from my long-ago youth was playing Rock'Em, Sock'Em Robots with my next-door neighbor. My parents wouldn't get me the game, for reasons I forget, but my friend Ronnie, who always got the latest, greatest games and toys, had a brand-new version.

As someone who visits job shops and manufacturers almost daily, I know why some are thriving, while others struggle. The ones that are thriving have invested and continue to invest in equipment, software, training and consulting services. Those struggling often say, "I would invest more in these areas, but I can't afford them because my competitors keep underbidding me.

All metals are not created equal. Therefore, neither are the machine tools for cutting them. Parts for extreme aerospace applications, such as in engines, landing gear and flap tracks, must be made of a heat- and corrosion-resistant metal, which typically has a high Young's modulus of elasticity and is difficult to machine.

The process of displacing metal instead of cutting it is called many things. But whether they call it form tapping, cold form tapping, thread forming, cold roll forming, roll forming, thread rolling, roll tapping or cold roll tapping, many metalworking professionals are unfamiliar with it, according to Peter Gennuso, applications engineering supervisor for OSG Tap & Die Inc., Glendale Heights, Ill.

The U.S. economy appears to be on the mend. In January, the Manufacturers Alliance for Productivity and Innovation gave a tentative thumbs up to sustained business expansion through the first half of 2013. And the Institute for Supply Management's manufacturing index rose again in January, painting an optimistic picture.

The spark gap is the physical distance the electric current has to jump off the wire to burn the workpiece when wire EDMing. Controlling the spark gap is critical to achieving required part dimensions and surface finishes.

Like most machine tool builders, Mori Seiki Co. Ltd. is focused on making its machines more energy efficient. In addition, the company is focused on making the factories that make those machines more energy efficient.

One of the most fundamental keys to running an efficient and cost-effective plant is having the right tool in the right place at the right time. While the cost of a milling or turning insert may range from a few dollars to significant investment, not having that tool available when needed can shut down an entire production line or more, resulting in missed delivery dates and lost profits.
