Abstract

One of the tests used to determine the mechanical properties of the metal are tensile test. The results obtained from tensile testing is the yield strength of the material. In the tensile test, applying load and extension of the material are manually analyzed. The research objective is to develop software and perform simulation of tensile testing test based on applying load and extension. Simulation results can determine the of technical strength and true strength of material the base on the results of tensile testing specimens of copper shafts circular cross section and angle shape cross section of construction steel specimen.

Abstract

In the process of the commercial vehicle lifting equipment production, there are many joining processes done by using electric welding. To find out the effect of the process, the tensile strength of the welding process is necessary to be tested. The information of welding strength on the commercial vehicle components is obtainable from the tensile test that has been done over the twelve specimens with the standard rectangular cross-section from the result of welding process. The results of the tensile test show the data of loading and extension that occurred which was then processed to obtain the value of the stress, strain and curves of each specimen. Testing from the specimen it is obtained that the yield strength 461.538 N/mm2, the tensile strength of 536.325 N/mm2, tenacity 2,451%, the elastic modulus of 353.955 N/mm2, resilience and toughness 0.652 and 876.363 N/mm2, with an error rate of 5%. The strength of the electric welding showed no significant difference compared to the strength without joining, and did not provide a great influence on the mechanical properties of commercial vehicle components lifting capacity of 2 tons, with an error of 5%. From this experiment it is concluded that electric welding on the equipment can provide sufficient safety. Keywords: Vehicle lifting components, electric welding, mechanical properties

Abstract

A machine tool must be able to produce high-quality product. But a skilled operator also required. The process of workpiece production begins with planning a logical working steps, such as: specifying the type of machine tool’s process and selecting the materials to be used. The production process is not only related to the technology, but also related to  the cost factor and the production speed to achieve the target and optimum profits. In the tensile test, the specimen is standardized according to the tensile machine that will be used. The shape of the tested specimen is essential in order to avoid cracking or facture in the grip or others areas. The purpose of this study are determining the average time of machining proces and getting the total cost of production of machining process of a tensile test specimen. The tensile test specimen were subjected on this experiment has a circular cross-sectiolan shape which made from concrete steel with the lathe machining proces. Based on the result of the process of time and cost calculation, the tensile test specimens has an average machining time of 161,733 minutes per specimen and the cost Rp. 63.483 per specimen. Keywords: Process time, production cost, the tensile test specimen

Abstract

This research was aimed to optimize a lathing cost by varying the cutting speed and cutting depth. A test was perfomed on 27 steel shaft AISI-1040 test objects with diameter of 25 mm and 150 mm long each, in order to obtain the optimum cutting time and cost in a lathing process. It was found that higher the cutting speed, the lower the total production cost, while the cutting depth does not affect the total production cost. The optimum average machining time is 3.153 minute/test object and the lowest total production cost is Rp.5,653/test object. The optimization made the target to minimize the total production cost was reached in cutting speed of 1600 rpm and cutting depth of 1,00 mm, with total production cost of the lathing process of the 27 test objects as much as Rp.16,960 Keyword: Optimization, Lathe, Cutting time, Production cost

Abstract

This research was aimed at knowing the cutting force a lathe with several parameters: rotation condition,varied cutting depth,and constant eater motion. The influence of the machining parameters to the cutting forcewas obtained by conducting tests on KNUTH DM 1000 A lathe.on every test with changing rotation and cutting depth, the electric current can be measured with ampere pliers. From the data of the electric currenst, the power and cutting force of every test can be calculated. From the test result and interacted two way variance analysis,it was found that the most influential parameters to the cutting force is the rotation,while the cutting depth does not influential the cutting force significantly, so it can be ignored. On 300 rpm gave the average cutting force of 2166 N, on 700 rpm 918 N,and on 1600 rpm. This results show that the rotation, the lower the cutting force. Keywords : lathe, machining parameters, cutting force

Abstract

The research was to compare two types of welding, i.e. electric welding and gas welding for the strength and the yield stress of a brackets made of angle steel conform  to JIS G 3101 material.The  results of strength has been done by previous researcher (Tumurang, 2014), while this research doing the strength of gas welding. The research shows that electric welding gives a better effect than gas welding. The tensile stress is 33.865%better, and the yield stress is 48.843% better. It is concluded that the welding of the material JIS G 3101 brackets is more appropriate to use the electrical welding than using gases of welding. Keywords: Strength of welding, Angle steel, Tensile test.
