Abstract :
Honing is a process for finishing surfaces to obtain smooth surface. This process is used for final polish of inner parts such as engines cylinders. Optimizing this process has always been a big challenge for mass production of cylinder blocks of internal combustion engines. Honing process has some variable parameters, thus to get their optimum rates the automobile cylinders were tested. In this research, experiment design was done using Taguchi method and to make input constant parameters of the test consistence, cylinder was bored using boring machine and in the next phase, cylinder was honed according to the design of experiment. Abrasive particles were selected from the material of carbide silicone stone and the variable parameters considered in this test were tangential speed, grain size, and the number of tools course. In order to measure surface quality of each cylinder, roughness tester machine was used and surface quality considered as output parameters of machining. Then, the results of the test were studied and analyzed on software environment. According to the tests conducted, the optimum values of mesh stone of honing and optimum values of numbers related to the course number and rotation were identified on the best state.
