Breathing Safely Around Metal 3D Printers February 8, 2016 When GE decided that additive manufacturing was the way to go for making metal fuel nozzles for its new LEAP engine, the company touched off interest in other shops to move 3D printers from the design studio to the factory floor. It also stepped up the focus on safety standards for metal AM.
Process Holds Keys to Efficient Titanium Machining January 1, 2016 Demand for machining titanium for aerospace applications won’t abate any time soon. It is driving OEMs and the supply chain in the commercial airplane market to find ways to dramatically increase machining output. Whatever date you pick from now until 2030, there’s a sufficient backlog of commercial airliners for both structural and jet engine applications to keep spindles humming around the clock cutting titanium.
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.
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.
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.
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.
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.
