Abstract

Milling process is one of the important processes in manufacturing. It can be defined as the machining procedure of utilizing rotating cutter to remove material from a work-piece. In this process, there are a few things that we must know especially type of clamping used. Basically, clamping or work holding is a generic term for any device used to hold the work-piece while machining process. Milling machine vise is one of the common clamping device that use in industry and for learning purpose. The purpose of milling vise is to reduce working time by permitting snappy set-up. Besides that, it also functions as a supporter during machining process and help to increase accuracy of the completed parts. However, these current vises have its own weakness. One of them is only limited surface of the work-piece can be cut in one single clamping. This required the operator to load and unload the clamping vise with a several times. Obviously, the process is not effective and efficient due to waste of time. In this project, the design of the clamping is presented for flexible positioning of the work-piece during machining process. This product will allow the manufacturer reducing their setup time and manual inspection. Besides, the machine used in the process to produce this product are milling machine and turning machine. After product is finished, one testing is done on the flexible clamping to evaluate the product which is surface roughness testing using Portable Surface Roughness Tester, SJ-401. Then, the result will compare to current vise result. From the result indicate that the average of Ra value using current vise as a clamping method is higher than using flexible clamping as a clamping method which are 1.543 when using current vise and 1.151 and 1.106 when using flexible clamping before and after rotation respectively for delrin as a work piece. While for aluminum as a work piece, the average of Ra value using current vise as a clamping method is lower than using flexible clamping as a clamping method which are 0.542 compared to 0.640 when using flexible clamping.
