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.”
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.
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.
Quality Scan: Thread Inspection: Your Application Matters June 1, 2009 Not all threaded connections serve similar purposes.The load-carrying needs of an aerospace engine support bolt in a tension assembly greatly exceed those of a simple screw that fastens a cover plate to an electrical wall socket. International thread-acceptance documents and standards recognize this basic engineering fact, and incorporate different thread-inspection requirements into their verification standards.
CMMs Grow Their Niche August 30, 2018 For CMMs, the good times continue to roll. “One of the surprising things that has happened in just the last three to four years is the sheer volume of CMMs that we are shipping,” said Angus Taylor, president of Hexagon Manufacturing Intelligence, North America (North Kingstown, RI). “The market seems to be really exploding.”
Metrology Certifications in the Knowledge Age May 7, 2018 Technology is changing ever more rapidly. Sometimes this means topics learned in engineering or technical school become obsolete. Whole new fields emerge within a few years, so that even those with freshly minted educations suddenly find themselves faced with new challenges.
Optical Metrology in Three Dimensions May 29, 2018 Basic trends in modern manufacturing are driving growth in 3D optical metrology. “One is the highly complex and high-tech material that manufacturers are using today. For example, in the aerospace turbine blade market, they simply cannot touch the part like they used to—the surface finish of the material is too readily affected by any kind of contact metrology."
Metrology Tools for In-Process Inspection October 12, 2017 While suppliers are under more pressure than ever to produce precision parts faster and with less scrap, in-process metrology means manufacturers can detect as soon as possible when a part is going wrong, correcting the issue quickly and saving it from scrap.
Hexagon Manufacturing Intelligence Advances Convergence July 5, 2017 Consolidation along the Digital Thread seems to be all the rage among companies today, including Hexagon Manufacturing Intelligence. While acquiring technologies outside its core metrology might make sense as a business, is there advantage technically in adding CAE and CAD/CAM?
