Ever since the plus/minus limits on dimensions first started to appear on engineering
drawings in the early 1900s, tolerances have been one of the most important issues for …

Three dimensional (3D) tolerance analysis is an innovative method which represents and
transfers tolerance in 3D space. The advantage of 3D method is taking both dimensional …

During the design and manufacturing process, the dimensional and geometric tolerances
assigned to parts will affect the required functionality through a stack-up of deviations …

Tolerance analysis aims to ensure the performance of mechanical products. However,
traditional analysis methods largely ignore the effects of form errors and local surface …

The aim behind applying functional tolerancing to a mechanism is to widen the tolerances
used in parts manufacturing according to the effective functional properties of the product …

This paper presents a model of prismatic parts (PPs) inspection planning on CMMs, in terms
of an intelligent concept of inspection planning. The developed model is composed of …

The dimensional and geometrical variations of each part of an assembly have to be limited
by tolerances able to ensure both a standardised production and a certain level of quality …

In most cases, designers have to manually specify both assembly tolerance types and
values when they design a mechanical product. Different designers will possibly specify …

Abstract The unified Jacobian-Torsor model uses the torsor model for tolerance
representation and the Jacobian matrix for tolerance propagation. The torsor model is …

Mechanical products are usually made by assembling many parts. The dimensional and
geometrical variations of each part have to be limited by tolerances able to ensure both a …
