Integrating GD&T into dimensional variation models for multistage machining processes

Recently, the modelling of variation propagation in multistage machining processes has drawn significant attention. In most of the recently developed variation propagation models, the dimensional variation is determined through kinematic analysis of the relationships among error sources and dimensional quality of the product, represented by homogeneous transformations of the actual location of ...

Quality Assured Setup Planning Based on the Stream-of-Variation Model for Multistage Machining Processes

Setup planning is a set of activities used to arrange manufacturing features into an appropriate sequence for processing. It has significant impacts on the product quality, which is often measured in terms of dimensional variation in the Key Product Characteristics (KPC). Current approaches to setup planning are experience-based and tend to be conservative by selecting unnecessarily precise mac...

a frame semantic approach to the study of translating cultural scripts in salingers franny and zooey

the frame semantic theory is a nascent approach in the area of translation studies which goes beyond the linguistic barriers and helps us to incorporate cognitive and cultural factors to the study of translation. based on rojos analytical model (2002b), which centered in the frames or knowledge structures activated in the text, the present research explores the various translation problems that...

Variation transmission analysis and diagnosis of multi-operational machining processes

In a Multi-operational Machining Process (MMP), final product variation is an accumulation, or stack-up of variations generated at all the manufacturing operations. In this paper, variation transmission in the MMP is analyzed by relating part variations to operational errors from machine tools, fixtures and datums. At each operation, total part variation is separated into several components cor...

Surrogate modeling of dimensional variation propagation in multistage assembly processes

In assembly process control and design optimization, it is critical to establish a mathematical model that describes the relationship between the dimensional quality of the final product and the various process parameters (e.g., the fixture layout and locator position deviation). This article presents a surrogate modeling methodology for multistage assembly processes to characterize the relatio...
