M O D U L A R   T O L E R A N C I N G   C O U R S E S Principles of Tolerance Management in Design and Manufacturing Description:  Designers invariably translate functional and assembly requirements of a product into prints of exact geometry augmented by material, surface, dimensioning and tolerancing specifications. Shape and specifications play a critical role in the functional aptitude, producibility, assembly and ultimate cost of the product. The modules contained in this course provide a comprehensive treatment of principles of tolerance management for the design, manufacturing and assembly of discrete components. The objective is to enhance operational skills required to generate, execute and manage economically producible designs. Elements of Geometric Dimensioning and Tolerancing Description:  One of the most important activities in product design and manufacturing is the transformation of product functional requirements into constraints on the geometry of individual components followed by economic production of these components within the prescribed constraints. The ASME Y14.5M-1994 Geometric Dimensioning & Tolerancing (GD&T) Standard provides a unique set of rules, symbols and analysis techniques used to specify and unambiguously communicate design requirements to everyone directly or indirectly concerned with the successful design, production and subsequent commercialization of a product. The successful introduction and application of this standard however requires various levels of understanding and competency to ensure that design, manufacturing, quality control, purchasing, etc. speak the same language. The material of this course is typically organized into the two modules: Introduction to GD&T Advanced GD&T Applications in Design Tolerance Management For Product Design and Manufacturing Description:  These are common symptoms of a lack of systematic procedures for tolerance management in product and process development. Tolerances or allowable errors are assigned to satisfy product requirements within the boundaries of processing capabilities. The smaller the tolerance values, the higher the product reliability (or the lower the maintenance or failure costs), and the higher the manufacturing costs. Economical tolerance values are normally determined using trial and error, which results in longer time-to-market and/or higher product costs. During this compact workshop, you will learn how to identify the core problems behind these symptoms and discover ways to systematically approach possible solutions. Tolerance Control in Discrete Part Manufacturing Description:  Designers invariably translate functional and assembly requirements of a product into prints of exact geometry augmented by material, surface, dimensioning and tolerancing specifications. Geometric dimensioning and tolerancing specifications play a critical role in the functional aptitude, producibility, assembly and ultimate cost of the product. The material contained in this module will introduce the participants to most tolerance analysis functions required for the planning, sequencing, set up and execution of a logical set of machining operations that will transform a raw material shape into a finished shape compatible with design specifications. Module topics include the specification and interpretation of geometric tolerance constraints, an introduction to the sources of dimensional and geometric variability in machining, error budgets of dominant machining operations, the treatment of design and manufacturing datums, elements of tolerance control in fixturing, conventional and adaptive tolerance management in sequential machining processes, tolerance analysis for operation sequencing in process planning and the fundamentals of dimensional metrology. One of the principal aims is to enhance operational skills required to analyze, influence and manage the producibility of a machined part. This page has been accessed 4179 times since July 2, 1999.
