Inspecting Complex Profiles

Using metrology software and a portable CMM, mold manufacturers can efficiently handle exceedingly complex surface profile requirements.More than ever moldmakers are pressed to push the envelope on what is feasible and reasonable when it comes to accurately creating complex profiles. Companies today are heavily vested in each new product they bring to market. And good is not good enough. Manufacturing specs are often riddled with GD&T (Geometric Dimensioning & Tolerances) annotations that must be met and reported on in first article parts. For a customer-centric brand these requirements are by no means un...

The GD&T Model

What you need to know about model-based GD&T for the manufacturing enterprise. Model-based Geometric Dimensioning and Tolerancing (GD&T) is powerful digital intelligence that can automate and improve quality across the entire manufacturing enterprise. A snapshot of the manufacturing companies implementing it and involved in the standards process points to the growing importance of this 3-D digital manufacturing technology: Spirit AeroSystems Inc.; Raytheon Missile System; Northrop Grumman Corp.; Caterpillar Inc.; The Boeing Co.; Lockheed Martin Aeronautics Co.; Ford Motor Co.; General Motors Corp.; Rolls-Royce Corp.; GE Aviation, G...

Keeping The F-18 Flying

How the NavAir Advanced Measurement Systems and Reverse Engineering Lab Keeps F-18's FlyingCalled the birth place of naval aviation, the United States Naval Base at Coronado Island, San Diego, CA (NBC) provides a shore-based platform for 16 helicopter squadrons, 2 fixed wing squadrons, two aircraft carriers, four SEAL (Sea, Air, Land) Teams, Navy Expeditionary Combat Command squadrons, and other air, surface and subsurface commands. The huge base is also home to the Fleet Readiness Center Southwest (FRCSW), which overhauls, repairs, and modifies Navy and Marine Corps front line tactical, logistical, and rotary-wing aircraft and their components. FRCSW airc...

Computer Aided Inspection

Closing the Loop On Digital Manufacturing Workflow, While Moving Toward a Model-Based Definition EnvironmentConmputer Aided Inspection (CAI) software helps CAD, GD&T (Geometric Dimensioning and Tolerancing datums), and measuring devices work together to ensure design intent, and eliminate the need for 2D inspection drawings, while closing the loop on digital workflow. These are all important considerations when moving towards a ModelBased Definition (MBD) environment. CAD-Based inspection is a good first step toward achieving a complete MBD environment. The central concept of MBD is that a 3D CAD model provides all product information needed for all a...

Portable CMMs Go to Inspection Source

Quality Magazine cover story, November 2010 Discover how rapid shop floor inspection makes quick work of Quality. By Ron Branch  For the machine shop that supplies the aerospace industry, portable coordinate measuring machine (PCMM) and model based definition (MBD) are everyday terms that are integral parts of its daily inspection routines. In the effort to drive quality and control processes, aerospace OEMs have altered the inspection methodology and the tools of their entire supply chain. Many of these suppliers are small- or mid-sized machine shops that have invested in inspection hardware, software and processes to satisfy strict quality s...
