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 …

It is widely acknowledged that the allocation of part tolerances is a highly responsible task
due to the complex repercussions on both product quality and cost. As a consequence …

The purpose of this paper is to study the use of the additive manufacturing (AM) method,
electron beam melting (EBM), for manufacturing of customized hip stems. The aim is to …

Traditional tolerance analyses such as the worst case methods and the statistical methods
are applicable to rigid body assemblies. However, for flexible sheet metal assemblies, the …

Accuracy design is an important and essential step for CNC machine tools, and traditional
methods always focus on the accuracy optimization itself and ignore other objectives, such …

It is very important to know how to allocate tolerances economically for parts in a CAD/CAM
system because this directly affects the machining costs of the parts. A new approach based …

Machining accuracy retainability is considered to be one of the most important aspects in the
process of performance evaluation and optimization design of the machine tools. Reliability …

The tolerance allocation is an extremely sensitive task due to the complex effects on quality,
product, and cost. Thus, tolerance allocation optimization covers design and manufacturing …

Tolerance-cost optimisation, ie using optimisation techniques for tolerance allocation, is
frequently used to determine a cost-efficient tolerance design that can meet the stringent …

Tolerance design has become a very sensitive and important issue in product and process
development because of increasing demand for quality products and the growing …
