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...

Powering Up an Age Old Design

Reverse Engineering Helps Power Companies Generate Up To 15% More PowerVerisurf Software helps power companies reverse engineer steam turbine rotor assemblies to support new and improved bladding. Southern California Edison, GE, Alstom, Siemens, Mitsubishi and Toshiba have all used Verisurf Software to create "as built" CAD models of existing rotor assemblies. Why go to all that trouble you might ask? After 130 years, steam turbines are still a wonderful and powerful design generating approximately 90% of the electrical power in the United States.  Most of the steam turbine power plants in use today around the world were built over 60 years ago, long before CAD ...

First Article Inspection Under 10 Minutes

Computer-aided design (CAD) and computer-aided manufacturing (CAM) have been around for a long time. But the goal of transforming to full model-based definition (MBD) has been elusive. One of the key disciplines where it has not been incorporated is in Quality Control. While organizations have partially employed model-based methods for CMM (coordinate measuring machine) inspection, most QA departments have continued to rely on drawings, manual techniques, and other non-digital means to complete the process. But now, moving the enterprise towards a fully modelbased process not only yields technical and process control benefits, but it can also greatly redu...

Scan It, Build It

When Gabe Draguicevich was asked to help fabricate a titanium hip implant based on CT (computed tomography, also known as CAT) scan data, he had to coordinate numerous technologies to complete the project. Because the CT data consisted of 2-D cross-sections, Draguicevich had to stack and align the individual scans to create a 3-D model, which he used to create a polygonal mesh in the form of a stereolithography (STL) file. After creating a prototype, he had to verify it against the original scan data, which was no mean feat considering that software capable of providing deviation analysis of the model surface to the STL file did not exist. Finally, Draguic...
