Abstract: Grinding is a process of machining to enhance surface performance and achieve a job piece’s dimensional precision. It is used as the method of cleaning as well as the primary method of machining. Grinding is generally the last starting procedure to be finished on the job unit and therefore any quality deviations such as geometric mistakes could not be approved on the surface finish for the next procedure. Rughness is one of the key reaction variables in the cylindrical grinding surface. Surface Surface roughness provides the value of the machined ground which is essential to decrease the frictional strength while out-of-roundness is of excellent significance for engines, axles, engines, screw chains, crankshafts, roller engines as out of roundness in these parts can contribute to unnecessary noise, shocks, unit failure, etc. Since we understand that the Taguchi technique used to enhance the performance of manufactured goods is generally chosen to optimize the texture of the surface. Since we worked on single machine, so with that respect this method is best suited as it is a single machine operational method. But machining parameters like wheel grinding rpm, feed rate, concentration of cutting fluid, etc., were constant in industry, and Taguchi method needs variation in such parameters. So due to this impact, this method is neglected and we opt for direct visualization on that particular machine. We took some jobs after certain values that was being grind and with the help of surface roughness tester machine, we took the readings. At some point, we started getting variations and after analyzing we found that particular count and reason which was due to grinding wheel not being dressed after that particular count. With this, the dressing time was reduced and optimization effects was described.
