3-D Model-Based GD&T for Inspection

Printed courtesy of Quality Magazine   Copyright ©2015. All Rights Reserved BNP Media The central concept behind model-based definition (MBD) is that the digital model contains all of the detailed information necessary for all aspects of the product life cycle. This includes everything from design to manufacturing, in particular, GD&T data.When the digital model is the authority it removes ambiguity, conflict and doubt that arises when drawings and models co-exist. When the 3-D model is the authority, MBD eliminates errors that result from referencing incorrect sources and makes processes more efficient.There is a common misconception that MBD is synon...

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 ...
