Abstract

In this design, the product we want to make is a die for the M 20 ring because the die we designed is helpful for student learning (practicum) at the Mechanical Technology Laboratory. The ring manufacturing process is carried out using one blanking compound dies. The blanking and piercing processes are carried out in one operation, thus saving time and money. This dies planning includes the process of designing dimensions and other supporting tools using the SolidWorks 2017 application. This design aims to produce blanking compound dies designs on press machines for the M20 ring manufacturing process with little or no defects and estimate the cost of making blanking compound dies. The method of analysis using Solidworks 2017 software includes displacement, von misses stress, safety factor. The results obtained from the 2017 SolidWorks analysis are to estimate the wear life of the punch and die to anticipate product failures. The material used in this ring is SAPH440 as defined in JIS 3113, starting from 2 mm to 14 mm. At the same time, the one we use for the M20 ring has a thickness of 2 mm. Based on the dies design calculations and data analysis that has been carried out, it is concluded that the use of blanking compound dies can reduce product defects due to dimensional accuracy in the dies and accelerate the production process of ring making.

Abstract

Honeycomb construction is a mimicry construction of a nest of bees/wasps form. The original form of honeycomb is hexagonal but in the development of the manufacturing process is transformed into other forms, e.g., quadrilateral, pentagonal, and polygonal. Honeycomb construction is widely used as a wall or panel because of its lightweight, lightweight obtained from the influence of the cavity due to the connection of each facet. In general, this honeycomb construction is not used for construction that receives either axial or radial loads. The axial load testing, especially using a three-point bending test was used in this research. The pineapple fiber-reinforced polymer composite is proven to have good damping ability which is expected to be suitable for alternative materials in the manufacture of the honeycomb structure. The honeycomb structure is hexagonal, which will be the core of a construction. The construction will be axially loaded which will be represented by a three-point bending test. In addition to direct testing, simulation of loading using Autodesk Inventor software will be compared and analyzed further. The mechanical properties, especially the bending stress for construction with a honeycomb core, are particularly useful in the design of an impacted construction, bent, and lightweight. The result of the simulation shows the difference with the test result caused by several factors, i.e., 1. The thickness of the honeycomb was not uniform, 2. There is a defect (air cavity) in the specimen, 3. Simulation has difficulties in determining the load and support of the nonsolid structure

Abstract

Waste in the form of garbage in the Piyungan area, Bantul Regency, consists of organic and non-organic waste, currently the condition is increasingly worrying because the landfills are very limited, so waste management must be managed optimally. To reduce the accumulation of excessive waste, a waste-cutting machine is needed. An efficient waste-cutting machine requires the right knife by choosing a knife between the crusher and shredder types. The selection of one of the blades used in the waste-cutting machine requires a design analysis using FEA (Finite Element Analysis) calculations and simulation assistance. Based on the results of the analysis of the calculation of the crusher-type knife using 4 blades, the required power is 2 HP, costs 8.8 million rupiahs and, the results of the FEA allowable stress test are 3.19E + 04, and 2.5 E + 08 are safe. While the Shredder type blade uses 13 blades, the required power is 2 HP, which costs 9.8 million rupiah and the FEA allowable stress test results are 1.53E+04 and 2.5E+08 safe. The results of the analysis obtained are that the selected crusher-type knife can be recommended for use in the design of a waste chopping machine because the manufacturing cost is 8.8 million and the Allowable stress is 3.19E+04,
