Design and Fabrication of Valve Lapping Machine

Abstract

Automobile maintenance is a major area in the industry of automobile and also a major income to the business. In present, Internal Combustion engine maintenance can be stated as a very important section in automobile maintenance and the valve lapping process that is subjected in this thesis is done during IC engine maintenance. The current methods used in most automobile maintenance businesses for valve lapping process are not effective and consume a lot of working hours. “Valve lapping Machine for Internal Combustion Engines” is a machine designed to overcome these problems by minimizing the human involvement in the process. The thesis consist of the background in designing the machine, methodologies used, results obtained by data analysis in order to optimize the design of the valve lapping machine. Lapping is a machining process in which two surfaces are rubbed together with an abrasive between them, by hand movement or using a machine. This can take two forms. The first type of lapping involves rubbing a brittle material such as glass against a surface such as iron or glass itself  with an abrasive such as aluminum oxide, jeweller's rouge, optician's rouge, emery, silicon carbide, diamond, etc., between them.
