Fast, Big and Easy: Trends in Metrology June 13, 2015 In this exclusive interview with Manufacturing Engineering, Norbert Hanke president of Hexagon Metrology shared his views on a number of high level topics that illustrates where Hexagon Metrology – and the industry – is headed in the next few years.
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.
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.
Interpreting the Language of GD&T in Metrology September 1, 2014 The industrial world is continuing its adoption of Geometric Dimensioning and Tolerancing (GD&T), the advanced tolerancing methodology. The symbolic language is intended to be both more precise while providing more latitude in allowable variations, replacing the simpler method of adding tolerances to each dimension.
New Metrology Culture Improving Chrysler Quality September 1, 2013 “Five years ago, our fit and finish was below average,” said Dr. Raj Kawlra, director of dimensional strategy and management of Chrysler Group (Auburn Hills, MI). “To be the future world-leaders, we knew that we had to focus on all aspects of quality … vehicles that look good, feel good, sound good, and are reliable.”
Grinding Roots August 22, 2013 Until the middle of 2010, first-tier subcontract machinist, JJ Churchill, could produce turbine blades only if they had their fir-tree root-forms preground elsewhere, or if they were subsequently added by another subcontractor. No longer is this the case.
Automating the Grinding Process June 1, 2013 Whether the process is cylindrical or profile grinding, automation, which can increase cycle time, throughput, consistency of part quality and taking real-time in-process measurements, is once again in demand. The reasons can be found in the benefits found in typical applications and the innovative and effective forms of automation available from machine builders like United Grinding Technologies Inc. (UGT; Miamisburg, OH), and their automation integrator of choice, Matrix Design Inc. (Elgin, IL).
Measure It On The Machine January 1, 2013 Why use a metrology device on or near a machine tool? It isn’t just useful for making sure a tool is present or monitoring tools for wear or breakage. On-machine measurement technologies can save time and money, by speeding up processes and eliminating extra personnel, and they are a critical step in the movement towards “lights-out” manufacturing.
Micro Manufacturing Keeps Shrinking the Envelope January 1, 2013 Micro components continue to shrink in size, demanding ever-greater precision and improved handling of parts with sub-micron-sized features. New approaches in micro machining technology include higher-precision systems from traditional micro machining developers, as well as techniques using additive manufacturing processes and semiconductor wafer-scale technology on the smallest of micro parts.
The Ins and Outs of In-Line Automated Inspection July 1, 2012 The challenges to manufacturing as it evolves into the 21st century are now familiar, and impact how metrology must contribute. Manufacturers face uncertain production volumes with roller-coaster demand, shorter production runs and faster product development cycles. Automation, while alluring as a way to reduce cost, needs to adjust.
