Study On Control Groove Shape Of Mechanical Ruled Gratin With Extension Pyramidal Graver

Mechanical ruled grating process is a very complex process, by supernatural precision diamond engraved graver in a thorium aluminum of glass, striking, such as oxygen copper or stainless steel, polishing the rough squeezed thorium membrane, make the material takes place plastic deformation at which the process.This article against mechanical ruled grating for echelle, through metal plastic deformation mechanics theory and the theory of finite element basis as for extension pyramidal graver ruled grating echelle of which the shape of a mechanism and technological research tools, establishing slipped the line and the velocity of extension pyramidal graver push the process and engraved in the process of the plastic mechanics model, for the echelle engraved into a mechanism to offer a theoretical foundation; by that Nm pressing mark technology test property of echelle aluminium which is simulation and to provide the basis of finite element, also use DEFROM-3D element simulation software have been engraved technology fully optimized, through are experiment to analyze the optimal combined and select range of parameter, try to rub mechanical ruled grating, to be accurate echelle which mechanical engraved process, and thus obtain better shape quality. through the comparison analogue result and the theory groove shape, may obtain the computer simulation simulation feasibility,and analyse the metal flow laws of aluminum materials, the distribute of equivalent stress and strain, provide the basis for this kind of diamond ruled graver directional and manufacture.
