Interesting changes have been happening at Haas Automation, one of the few American machine tool builders left standing after scores have been displaced over the decades by Japanese, German and Korean builders.

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.

Modern manufacturing is rapidly adopting model-based definition (MBD). When employing an MBD strategy, the CAD model becomes more than the nominal to which all parts are measured and inspected against. MBD keeps the all-important digital thread intact—from design to manufacturing to inspection and quality reporting.

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.

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 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.”

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.

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.

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.

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.
