The objective of the project is to prepare a machine which gives good surface finishing to work piece without human efforts but operates pneumatically. Compressed air is used as working media. The compressed air moves tool to give smooth finishing. The idea of the project generated due to a manual surface finishing to wood in our workshop. In that operation work piece is fixed and one sand paper is used to do the finishing operation. But in that operation we need to apply more force to give good surface finishing and workers need to work continuously on particular work piece. For mass production in large scale industry to reduce the human efforts pneumatic machine should chose. Hence for some development of machine, we have chosen this subject for our project. We hope that a good idea will develop and we can use it in many industries in surrounding and our practical knowledge, team-working skill, leadership skills will be improved. Surface finish, also known as surface texture or surface topography, is the nature of a surface as defined by the three characteristics of lay, surface roughness, and waviness. It comprises the small local deviations of a surface from the perfectly flat ideal (a true plane). Surface texture is one of the important factors that control friction and transfer layer formation during sliding. Considerable efforts have been made to study the influence of surface texture on friction and wear during sliding conditions. Surface textures can be isotropic or anisotropic. Sometimes, stick-slip friction phenomena can be observed during sliding depending on surface texture. Each manufacturing process (such as the many kinds of machining) produces a surface texture. The process is usually optimized to ensure that the resulting texture is usable. If necessary, an additional process will be added to modify the initial texture. The latter process may be grinding (abrasive cutting),polishing, lapping, abrasive blasting, honing, , milling, lithography, industrial etching/chemical milling, laser texturing, or other processes. Pneumatic systems are safer than electromotive systems because they can work in inflammable environment without causing fire or explosion. Apart from that, overloading in pneumatic system will only lead to sliding or cessation of operation. Unlike electromotive components, pneumatic components do not burn or get overheated when overloaded.
