Plastic Injection Molder Turns to Gun Making October 1, 2015 In 2006, Jim Pontillo, founder of TRA Medical Inc. (Placentia, CA), saw two distinct trends: his medical mold-making workload was diminishing and demand for guns and gun components was rising. Sizing up TRA Medical’s core competencies, Pontillo saw an opportunity for growth in the development and production of 9-mm handguns. Today, these guns are branded and sold under their own brand FMK Firearms, which is a stand-alone business.
Metrology Gets Connected September 1, 2015 “Metrology and its relationship to manufacturing is rapidly evolving,” Ken Woodbine, president, Wilcox Associates, a brand of Hexagon Metrology (North Kingstown, RI), recently observed. “We are seeing larger quantities and faster speeds of measurement data collection. The next challenge is what to do with all that data.”
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).
Picking the Right Toolholder for the Toughest Jobs August 1, 2015 When sizing up an application for a milling toolholder, it is necessary to consider the materials being machined, how aggressively metal is going to be removed, and any machining conditions that are likely to present a challenge to tooling security. By now, the pros and cons of hydraulic, mechanical, and heat-assisted shrink-fit systems are well known and results well documented.
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.
The Increasingly Perfected Science of Machining Composites April 1, 2015 A 1965 Shelby Cobra 427 shown at the Detroit Auto Show was additively manufactured on a Cincinnati BAAMCI machine by DOE’s Oak Ridge National Laboratory (ORNL), one of seven founding members of the Institute for Advanced Composites Manufacturing Innovation. The Detroit IACMI branch will get $70 million to develop a robust supply chain to improve materials, handling, and machining properties for automotive composites.
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.
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.
