"Pressure" and "flow" are common terms when discussing air compressors, but the relationship between the two is often misunderstood.

Measuring machined parts on a surface plate has long been a tedious job, one that requires mastery of dial indicators, a pocket calculator and an adjustable height gage that most in the industry refer to as a "Cadillac gage." But several metrology providers offer a more sophisticated way to quickly and accurately check hole diameters, the distance between part features, centerlines and more. The tool is called an electronic height gage, and it has made Cadillac gages about as popular as whitewall tires.

Like a broken record, decision-makers at parts manufacturers continually hear that monitoring machine tool utilization rates helps improve productivity. That's true, but the phonograph needle frequently skips over three other benefits of machine tool monitoring.

Maintaining constant cutting forces provides a constant radial tool engagement throughout the entire cut, which eliminates spikes in the cutting forces. This approach allows the programmer to take a larger axial DOC while simultaneously maintaining a high feed rate and extending tool life.

With its new EOS M 290 additive-manufacturing system, Indiana Technology and Manufacturing Cos. (ITAMCO) now 3D-prints medical devices. After obtaining the system in June, the company started shipping components in August.

Machining Inconel 718 and similar heat-resistant superalloys (HRSAs) at cutting speeds normally reserved for aluminum is not only possible but becoming an accepted practice at some aerospace OEMs.

Nowhere will you find more gold — i.e., profits — than by streamlining redundant or antiquated plant operations, according to Phillip Canipe, whose job it is to eliminate waste and redundancy at manufacturing plants.

At Mitsubishi Hitachi Power Systems Americas Inc., holemaking success is about timing—finding the best sequence in which to perform manufacturing operations.

What would cause parts manufacturers not to want to extend tool life, increase speeds and feeds, enhance chip evacuation to avoid recutting, impart finer surface finishes and eliminate pecking when deep-hole drilling? Apparently, ignorance in the marketplace.

Visioneering Inc. employees stay ready to adapt to change as the Auburn Hills, Mich., aerospace supplier opens a new facility and adopts a new way to apply coolant.

Today's machine tool users have more spindle choices than just the steep-taper designs developed 40 years ago.n

Many — if not most — shops encourage employees to purchase their own measurement tools. Some even help by "financing" these purchases, allowing machinists to pay them off in small increments. And what machinist doesn't want his or her "own stuff" with which to do the job? But does allowing machinists to use their own measuring tools actually make sense?
