Research on Accuracy Design of Mechanical Design

Abstract

Abstract. Mechanical design contains three part: firstly, organization design; according to working requirement of machine, properly choose transmission form and executive body, so as to realize mechanical movement, and the result is showed by mechanical movement diagram. Secondly, structural design; according to machine’s load level, Meeting the request of mechanical strength and service life consider Structure technology and assembly processes, and determine the machine’s parts and assembly drawings. And thirdly, accuracy design; according to the function requirement of machine, select the appropriate dimensional accuracy, shape accuracy and surface roughness, in order meet the requirement, raise product quality, and reduce costs at the same time. There has already been plenty of paper dealing with organization design and structural design, but very few dealing with accuracy design.
