A REVIEW PAPER ON: A MEASURING TECHNIQUE FOR SURFACE FINISH

Abstract

The study of surface thus becomes important for the proper understanding of the operation, hazards and maintenance in machinery. Machine components when manufactured with high precision run quite smoothly. The various machining processes like grinding, lapping, electro-polishing etc. produce highly finished surfaces than those produced by conventional machining methods.The findings of this project work include a method that is reliable and effective. This technique is again a contact type profilometer but does not involve rubbing of the surface to be measured with any stylus. This technique is based on fluid method of the measurement. The costing of the presently available surface roughness measuring instruments whether contact or non-contact types are very expensive. This Pneumatic Profilometer developed uses pneumatics for the achievement of the objective
