Honing is generally used as finishing technology in manufacturing valves. It consist of multi-stone tool which rotates and reciprocates in motion in axial direction. Honing stones are expanded to the machined surface by special rigid mechanism that provides cutting of work-piece cylindrical surface. The tool vibrates in transverse and axial direction. In this research, we aim to improvise and solve the problems faced while machining i.e production of scratches and chatter marks on internal surface of cylinder, ovality and tapper produced while operation. Formerly, we took a brief analysis of the manufacturing defects including chatter marks, scratches, tapper marks and then studied the parameters affecting it. After a vast research on the machining process and components, we finally discovered the main causes of these problems and found out the solution and implemented the solution. The next step we took was implementation of results and analysis of our calculations and research done. Modifications done will improve and will result in smooth continuous machining operation. A series of honing equipments were carried out to calibrate the parameters and coefficients of model. The modified model thus show good accuracy and smooth surface finishing of products with a long run time and less distortion.
