Advanced Computer-Aided Fixture Design

Description:

Fixtures--the component or assembly that holds a part undergoing machining--must be designed to fit the shape of that part and the type of machining being done. This book discusses the fundamentals of Computer-Aided Fixture Design (CAFD) techniques and covers fixture planning, fixture design (both modular and dedicated fixtures), fixture design verifications, and the overall integration with CAD/CAM. The book shows how CAFD may lead to a significant reduction of product and process development time and production cost, and how CAFD can increase quality assurance through simulation and science-based technical specification and cost estimation in business quoting, especially in current supplier-based manufacturing. It also provides case study examples and will offer software with demonstration systems.

描述：
夾具是用於夾持正在加工的零件的組件或裝配件，必須根據該零件的形狀和加工類型進行設計。本書討論了計算機輔助夾具設計（CAFD）技術的基礎知識，包括夾具規劃、夾具設計（模塊化和專用夾具）、夾具設計驗證以及與CAD/CAM的整合。本書展示了CAFD如何能夠顯著減少產品和工藝開發時間和生產成本，以及如何通過模擬和基於科學的技術規範和成本估算來提高質量保證，特別是在當前基於供應商的製造中。它還提供了案例研究示例，並提供帶有演示系統的軟件。
