Design and fabrication of an automatic grinding machine

Technical Report in the subject Design (Industry, Graphics, Fashion), , language: English, abstract: Grinding is one of the most important manufacturing process for high precision parts. Grinding characterized by low material removal rate and high surface finish is an abrasive machining process. Geometrically undefined grits of grinding wheel influences part surface finish. Cutting edges worn out during grinding are retained by timely dressing. An operator on shop floor decides on the dressing interval based on end of wheel life such as burns, chatter marks and deterioration in the work piece surface finish. Incorrect dressing of grinding wheel increases unnecessary machining time and wheel wastage. Grinding is an abrasive machining process which is used to improve the surface quality and to achieve dimensional accuracy of a work piece. In grinding, a grinding wheel is used as a cutting tool and material is removed from the work piece. In grinding surface roughness and material removal rate are considered important output responses for quality and quantity of production. In cylindrical grinding out-of-roundness is another important output parameter. It is radial run out of the cylindrical work piece and it is difference between minimum and maximum radius.
