Abstract

In grinding operations, surface grinding is the most common machining process which provides finishing process that uses the method of a rotating abrasive wheel to give them more refine look or attain a desired surface roughness for a functional purpose by smoothing the flat surface of metallic or non metallic materials. In grinding operation, there are many parameters that are important and need to be controlled in order to have the desired surface roughness such as the movement table speed, depth of cut and the position of work piece being machined. All the parameters will give a great impact on the surface roughness. The objective of this study is to analyze the surface roughness that reflects to grinding cutter condition parameters and to identify the optimized grinding parameters to attain the good surface finish. The study is conducted by performing grinding operation to the work pieces according to the parameters and the surface roughness was checked for each of it. There are three parameters that were controlled in this study and they are the work piece position which is vertical, horizontal and cross; the cutting depth which is 2µm, 7µm and 15µm; and three type of table speed which is low, medium and high table speed. The results from this study shows that the optimum work piece position for roughing and finishing process is in cross position which the work piece lay is crossing to the grinding wheel as the surface roughness for this condition is better than the other two position which is vertical and horizontal. Besides that, the study also confirm that in order to get the optimum surface roughness for roughing process is by using 15µm of cutting depth and for finishing process is by using 2µm of cutting depth and both process are using medium table speed.
