Abstract

The reverse engineering process in development is widely used to carry out the reverse engineering process for the design of certain products, in this study the reverse engineering process on the palm oil lorry wheel is to improve the design as well as a combination of materials to increase the life of the lorry wheel product in the palm oil processing. The process of scanning the surface of the lorry wheel using camera and the reverse engineering process is carried out by measuring the precision of the lorry wheel by measuring using a precision measuring instrument, data obtained by measurement and reconstruction model. data obtained by measurement and reconstruction model using CAD software and CAE software used to analyze the CAD and CAE software are used to analyze the design results after the reverse engineering process. reverse engineering process. So, it is necessary to develop a reverse engineering system design that will be useful in terms of efficiency and service life of the lorry wheel, in the design of this lorry wheel uses CAD and CAM software to model the lorry wheels with simulation and analysis systems. The next process is to modify and remanufacture the lorry wheel model using machine tools so that the prototype of the manufacturing process can be tested. so that the prototype of the manufacturing process can be tested on the lorry to see the durability of the reverse engineering product. to see the durability of the reverse engineering product. The results of this research showed that the reverse engineering data can be interpolated for further CAE process

Abstract

The COVID-19 pandemic has not only resulted in significant loss of life but has also caused a critical shortage of Personal Protective Equipment (PPE) for healthcare workers. In response, the global community has leveraged 3D Printing technology to produce face shields. This study aims to analyze and evaluate the conformity of the dimensions of 3D-printed face shields with the head anthropometric measurements of the Indonesian population. Anthropometric data from three head segments (Head Length/D1, Head Breadth/D2, and Face Height/D3) were collected from 377 subjects. Three face shield models (PW1: low grade, PW2: medium grade, PW3: high grade) were manufactured using a 3D Printing machine. The analysis results indicate that the existing designs are not fully compatible with the percentile dimensions of the Indonesian population. Modifications to the frame and visor dimensions are required to better align with Indonesian anthropometric data. Additionally, adjustments in 3D Printing process parameters and improved product quality are essential to achieve a more ergonomic design.
