Abstract

The machining process of dry machining milling method is a machining process without additional coolant, but this method has several problems during the process and after the machining process, namely Tool temperature can easily rise and has a major impact on tool wear, so the purpose of this research is to develop a dry machining method with variations tools that are coated with nickel, by utilizing the properties of nickel material that can withstand heat and corrosion, therefore a nickel coating is used on the tool which will affect the temperature parameters of the tool. The coating method that will be carried out is the electroplating method. This method is a metal coating method which is often called electrodeposition, or the process of depositing the coating metal on the base metal using electrolysis. This research was carried out using experimental testing methods to obtain tool temperature parameters and hardness on the tool coating. The voltage used in the electroplating process is 6 V/ 0.7 A for 5, 10, and 15 minutes to produce a nickel layer thickness of 0.024 mm in 15 minutes, so every 5 minutes the layer is 0.08 mm. The experimental testing process used the HSS tool Ø 12 / 4 F and a aluminum 6061 workpiece which resulted in an intermediate temperature that was not coated with nickel (uncoated) at 3 mm feeding spindle speed 3000 rpm the temperature reached 73.6 ºC while that which was coated with nickel (coated) the temperature only reached 58.6 ºC, and get an average hardness value on the nickel layer, which is 279.9 Hv

Abstract

The purpose of using natural fibers as reinforcement for composite materials is expected to be an alternative material to replace the used of fiberglass fibers and is expected to be able to increase the quality of water hyacinth fibers and coconut coir fibers. In this study, to determine the best tensile strength value, several experiments were carried out using the determine factor of the fiber volume fraction of 20%, 25%, 30% and the immersion factor with NaOH solution for 4 and 6 hours using a matrix in the form of epoxy resin. The test results showed that the variation of soaking in alkaline solution media (NaOH) for 6 hours with a volume fraction of 30% obtained the best tensile strength results with each type of fiber, water hyacinth fiber obtained the best results of 23.32 MPa while coco fiber the best result was 22.10 MPa.

Abstract

Current leakage in parallel gap single-sided double spot welding tools occurs if the insulation to the mass-body, either from the work table or the drive system, can reduce the current concentration and result in double-sided welding being relatively difficult to carry out or the weld results being poor. Therefore in this research, an experiment was carried out to test the machine how big the effect of leakage current is on the quality of welded joints by comparing the strength of the joint between a system without insulation and a system using insulation using the independent sample t-test statistical method with a confidence level of 95%. The results of the study show that overall the max load for CT 3 to 10 is a mean difference between without and with insulation, although it is not very significant, this is because the shear test data from the group without insulation has quite a high deviation. High deviations also occur in the upper yield data, the strongest conclusion is that providing insulation (or preventing leakage current) provides a more consistent welding result as seen from the results of the shear test data. Only CT 3 has a significant impact on both max load and upper yield.
