Abstract

Along with the development of increasingly advanced technology, the need to facilitate human activities is increasing. Many tools are created to facilitate human activities. Especially work that is heavy and dangerous when humans do it. One of them is the trolley as a tool for transporting goods. The tool in the form of a trolley has a main frame which is the place to be placed for loading. The material used in the main frame of the trolley is hollow galvanized with a size of 20x20x1.5mm. In this study, the analysis and calculation of frame strength using Solidworks software, with a static simulation feature so that the value of the stress that occurs can be known. Based on the results of the test, the maximum stress on the frame is 158,800,000N / m², the deflection is 4533mm, so it is concluded that the trolley frame that uses a hollow galvanized material (Hollow Galvanize) can be said to be able to withstand a load of 30kg, and it is known that trolleys can be used to help transport shopping goods. and bicycles can function according to design.

Abstract

In today highly sophisticated manufacturing industry, of course,the best product results are needed. Machining work, especially on CNC turning machining needs to be considered roughness level. The lower the roughness level,  the better the workmanship will be. For this reason it is necessary to pay attention to the parameters used so that the roughness of the product is getting lower. This study aims to determine the best parameters. The machining process is carried out on the MORI SEIKI SL-25B/500 CNC turning and S45C material. Parameters used consist of  feed motion, feed thickness, and spindle speed. The experimental design was based on the taguchimethod with an orthogonal L9(33) matrix and 2 times of replication as a comparison, there was no significant deviation. From the research, the contribution of feeding motion is 49,734%, feeding thickness is 19,239%, and spindle speed is 7,334%. The smallest roughness in the MORI SEIKI SL25B/500 CNC turning machining process was obtained from setting the feed motion 0.2 mm/rev, feeding thickness 1 mm, and spindle speed 2000 rev/minute.
