Portable Coordinate Metrology for Large Cast Part Machining

Machining large parts, especially castings, is not for everyone.  The generalization ‘parts are parts’ does not apply in this case.  To be proficient requires commitment to constant process improvement, equipment evaluation and investment.  And to top it off, mistakes are very expensive. There are unique challenges associated with machining large parts, today.  Customers are demanding ever tighter tolerances, parts are large, heavy and quite often castings.  Increasing quality and efficiency is a tall order – how can you do both?  TCI Precision Metals approached  the challenge by analyzing variables of the machining process th...

Model Based Inspection of Aerospace Parts

Participants in the aerospace industry have substantially reduced if not eliminated the use of 2D drawings to convey dimensional and design intent information about parts and assemblies throughout the various stages of manufacturing. The industry has accomplished this via the widespread implementation of Model Based Defini-tion (MBD), particularly by OEMs and their First-Tier suppliers. The use of a single authoritative digital source of part information has numerous systemic benefits, including:Eliminating errors that result from referencing an incorrect source.Making processes more efficient—no more searching to determine correct revision levels.Eliminating ...

Composites Manufacturer Produces More Parts with Verisurf

"“The traditional method works, but it’s slow and not very accurate. The FaroArm offers accuracy comparable to fixed CMMs and software that is fully programmable for repetitive measurement so it greatly increases both the speed and accuracy of the inspection process. The result is that we are able to get more parts out the door with the same people while maintaining higher standards of quality.”Unitech Composites and Structures, a division of the AGC Aerospace & Defense Composites and Structures Group, designs and manufactures composite structures in commercial and military aerospace markets. Most of these parts have critical dimensional and structu...

New Collaborative Project Will Give Manufacturing Some New Digital Threads

Reference NIST Tech Beat for January 7, 2015 National Institute of Standards and Technology (NIST) researchers and their industrial partners aim to add a new dimension to manufacturing capabilities. In a new project, they will demonstrate the feasibility—and benchmark the advantages—of using standardized, three-dimensional (3D) models for electronically exchanging and processing product and manufacturing information all the way from design through inspection of the final part, a tightly integrated, seamless string of activities that manufacturers are calling a "digital thread". Compared with the prevailing practice of converting two-dimensional (2D) computer...

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...
