Producing assemblies that experience little to no rework during assembly fit-up is a
perennial challenge in offsite construction. While the traditional response has been to solve …

The accumulating effects of dimensional and geometric variability in modular construction
have traditionally been managed using trial and error strategies and use of standardized …

A computer simulation method of assembling parts of a mechanical assembly has been
developed by Deere & Company to statistically analyze tolerance stack-up of complex two …

The assembly of discrete parts is strongly affected by imprecise components, imperfect
fixtures and tools, and inexact measurements. It is often necessary to design higher …

A case from the authors' experience reveals that dimensional tolerance, in terms of physical
dimensions of components and their position within the system; interact to compound the …

As a first step in developing a synthesis technique for assisting designers to specify
tolerances in product design, a new 3D statistical tolerance analysis approach is proposed …

Tolerance, representing a permissible variation of a dimension in an engineering drawing, is
synthesized by considering assembly stack-up conditions based on manufacturing cost …

Nominal dimensions may not be achievable during manufacturing processes, due to
technological or financial limitations. Therefore, tolerance allocation is of significant …

Simulations of products and production processes are extensively used in the engineering
phase. To secure good geometrical quality in the final product, tolerances, locator positions …

This paper presents a new tolerance modeling and analysis methodology through a two-
step linearization with applications in automotive body assembly. The first step is to …
