Grinding Gamma Titanium Aluminide August 13, 2015 Titanium aluminides possess many characteristics that make them highly attractive for high-temperature structural applications in automotive and aerospace industries. Their high specific strength, high-temperature stability and oxidation resistance relative to conventional titanium and nickel alloys make them beneficial for use in low-pressure turbine blades for aerospace engines, as well as turbochargers and exhaust values in automotive engines.
3D Printing Orthotic and Prosthetic Devices August 7, 2015 3D printing has become the medium of the new technological revolution as its applications diversify from printing food to weapons, from clothing to industrial products. It is also finding more uses in the medical space, including Orthotics and Prosthetics (O&P).
Advances in Hand-Held Metrology August 1, 2015 While high-end metrology devices like advanced laser scanners or precision CMMs garner a lot of attention, it is hard to imagine any industrial setting without the presence of work-a-day hand-held, contact metrology tools such as calipers or micrometers. That is what Justin Frazzini, quality manager for A.A. Jansson (Waterford, MI), retailer and calibration and repair service provider, observes in his practice.
DIY: Creating Through-Tool Coolant Capability June 1, 2015 New retrofit systems make it possible to quickly, easily and cost effectively transform the standard external-coolant live tooling heads on turning machine turrets into those with through-tool-coolant capability. And shops that have done the retrofit are experiencing longer tool life, more efficient chip control and less heat generation.
What’s Next in Grinding? March 1, 2015 Many precision grinding machines on the market already offer their users near-perfect tolerances, leaving one to wonder: What’s next in grinding? But tool builders still have plenty of room to add valuable new improvements, machine shop owners say.
Not Going Down the Drain March 1, 2015 Metalworking fluids have never been the most glamourous part of manufacturing. That’s been reserved for areas such as additive manufacturing, where complete parts are printed from a digital file, one layer at a time. However, most manufacturing today still consists of parts being cut, shaved or otherwise machined.
Milling vs. Grinding for Rapid Stock Removal February 16, 2015 A recent effort by the Norton Advanced Applications Engineering Group demonstrates that for difficult-to-machine materials, grinding can be an economical alternative to other machining processes.
Advanced Technologies for Machining Oil-Field Parts January 23, 2015 Despite falling oil prices, the investment valve in the oil and gas industry remains on—for now—as manufacturers continue their race to provide large, precision parts for fracking, subsea drilling and other related activities. But as anybody in the energy sector knows: this is the land of boom or bust.
Extrusion and Drawing Knowledge January 2, 2015 Extrusion and drawing, two related, stalwart topics in material forming, are covered from top of punch to bottom of die in more than 200 papers in the SME Technical Paper library. The range of contributors is broad, from companies like Alcoa, Westinghouse, ASEA, Western Electric and General Electric to universities in Japan, Germany and the US, as well as individual entrepreneur metalworking shops.
Change-up Pitch: From Metal to Plastic October 2, 2014 Even though it’s been around since the 1950s, when engineering-grade resins were first introduced, many manufacturers still are not familiar with the many benefits that metal-to-plastic conversion provides.
