The manufacturing cell design problem aims at organizing a manufacturing plant in cells that contain machines processing parts from a same family for a given product. The purpose is to minimize the flow of parts among cells so as to increase productivity while reducing costs. This paper focuses on comparing metaheuristics and constraint programming –from a modeling standpoint– when used to solv...

In this work we address the problem of tolerance representation and analysis across the domains of industrial inspection using sensed data, CAD design, and manufacturing. Instead of using geometric primitives in CAD models to define and represent tolerances, we propose the use of stronger methods that are completely based on the manufacturing knowledge for the objects to be inspected. We guide ...

Ikeda, M., Ohtsuji, H., Kawai, H., and Kuniyoshi, M. (1971). Brit. J. industr. Med., 28,203-206. Excretion kinetics of urinary metabolites in a patient addicted to trichloroethylene. A male Japanese subject, single, aged 38, who worked at a workshop washing metal parts with trichloroethylene, was admitted to our clinic due to addiction to the solvent. Analyses of urine revealed the presence of ...

Abstract Load-oriented lightweight structures are commonly designed based on topology optimization. For machine tool parts, they enable the reduction of moving masses and therefore increase resource energy efficiency production systems. However, this usually results in complex part that difficult or impossible to produce using conventional manufacturing methods. In paper, a hybrid layer laminat...

The processes of metal additive manufacturing (AM) are no longer confined to rapid prototyping applications and seeing increasing use in many fields for the production tools finished products. ability design parts with practically zero waste, high precision, complex geometry, on-demand fabrication among advantages this approach. One drawbacks technique is productivity rate, as made layer by lay...

Overview: Given the ongoing advancements in additive manufacturing (3D printing), many companies are considering using this digital technology for supply of spare parts. This study identifies advantages and barriers context parts chain management. The case examines perspectives a manufacturer customer chain. We present several questions that practitioners can use to (re)consider their companies.
