Automobile maintenance is a major area in the industry of automobile and also a major income to the business. Present, 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 engine maintenance. Methods used in most automobile maintenance for valve lapping process are not effective and consume a lot of working hours. 'Valve lapping Machine is a machine designed to overcome these problems by minimizing the human involvement in process. It consist of the background in designing the machine, results obtained by data analysis in order to optimize the design and design of the valve lapping machine. Lapping is a machining process in which two surfaces are rubbed together, 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 with an abrasive such as aluminium oxide, jeweller's rouge, optician's rouge, emery, etc., between them. This produces microscopic conchoidal fractures as the abrasive rolls about between the two surfaces and removes material .The other form of lapping involves a softer material such as pitch or a ceramic for the lap. The softer material, which holds it and permits it to score across and cut the material. Taken to a limit, this will produce a surface such as with a polishing cloth on an automobile, or a polishing cloth .Taken to the ultimate limit, with the aid of accurate interferometer and specialized polishing, lens makers can produce surfaces that are flat to better than 30 nanometers. Surfaces flat can be molecularly bonded by bringing them together under the conditions.
