Processing of Beryllium for High Technology Applications

Abstract

Unique combination of physical, mechanical and thermal properties, that beryllium possess makes it an ideal candidate material for space applications, as for examples, in Inertial Guidance Systems, Spacecraft Mechanisms, optics and Structural Element). Its inherent nuclear properties makes it attractive in nuclear programmes. Besides these, it has been a recommended choice in computers, micro electronics, audio industries and medical for high technology systems. Though beryllium is readily machinable for high precision accuracies and excellent surface finishes, yet it has tendency to chip off or edge crack and prone to residual stresses and surface damages. Additionally, inhalable beryllium dust fumes generated during machining is injurious to health. In order to achieve desired accuracies, processing of beryllium calls for appropriate fixturing, adoption of proper cutting parameters, toolings, operation sequencing and proper handling, and job analysis. This paper takes a stock of the present technology a...
