Clarifications of Rule 2 in Teaching Geometric Dimensioning and Tolerancing

Teaching Geometric Dimensioning and Tolerancing in a Manufacturing Program

Feature-based Geometric Dimension and Tolerance Modeling System

This paper reports a complete system for modeling, representation, and validation of geometric tolerances, using feature-based approach from boundary representation (B-Rep) based solid models. The utility of feature based representation scheme for representing Geometric Dimensioning and Tolerancing (GDT) information in geometric models is highlighted. Explicit information from B-Rep is culled u...

Sequential Design of Optimum Sized and Geometric Tolerances

Tolerancing has great impact on the cost and quality of a product. Dimensional and geometric tolerancing are designed to ensure that products meet both designed functionality and minimum cost. The task of dimensioning and tolerancing in process planning stage is to determine the working dimensions and tolerances of the machined parts by given blueprint (B/P) specifications. A lot of research wo...

A functional tolerance model: an approach to automate the inspection process

Purpose: Purpose of this paper is the definition of a framework to describe the Technological Product Specifications (TPS) and the information associated with the geometric dimensioning and tolerancing to integrate the design concepts into a commercial inspection system. Design/methodology/approach: A functional tolerance model provides a complete framework to define the geometric dimensioning ...

Process-based tolerance assessment of connecting rod machining process

Process tolerancing based on the process capability studies is the optimistic and pragmatic approach of determining the manufacturing process tolerances. On adopting the define–measure–analyze–improve–control approach, the process potential capability index (C p) and the process performance capability index (C pk) values of identified process characteristics of connecting rod ...
