Abstract

FERNANDA ANDI NOVIAN, 2024. "Design and Manufacture of Bookshelf Prototype with CNC Laser 〖CO〗_2" Mechanical Engineering Thesis, Faculty of Engineering and Computer Science, Pancasakti University Tegal, 2024. Design is a process of defining something that will be done using various techniques and it involves a description of the architecture as well as detailed components and limitations that will be experienced in the work process. In this case, the author designed and made a prototype bookshelf product using acrylic material. The design design process can be carried out using Solidworks 2016 software and analyzing the strength of the bookshelf prototype design. After that, carry out the manufacturing process using a CO₂ CNC Laser. In this research, there are 2 data that will be taken, including the design process and the results of the design analysis using Solidworks 2016 software. In the design process there are several stages, the first stage is designing part 1, the second is designing part 2, and the third is assembly. As for the results of the analysis, data will be obtained such as stress analysis, displacement analysis and strain analysis. After carrying out the design and analysis process, the results were obtained that the design process consisted of 3 shelves, each of which had the same load test, namely by being given a load of 1 kg or 10 Newtons. From the results of tests carried out with a load of 1 kg, the following results were obtained: for the results of the first shelf stress analysis, the minimum value was 7.243 x 10-10 N/m2, the highest was 2.957 x 105 N/m2. The minimum stress value for the middle shelf is 2.497 x 10-8 N/m2, the highest is 2.965 x 105 N/m2. The minimum stress value for the bottom shelf is 7.201 x 10-8 N/m2, the highest is 2.980 x 105 N/m2. In stress analysis, good results are found on the top shelf, because it has the lowest value compared to the others, so the top shelf will not break easily. For the results of the first shelf displementation analysis, the highest value is 5.559 x 10-1 N/m2. The middle shelf has the highest value of 5.559 x 10-1 N/m2. The bottom shelf has the highest value of 5.563 x 10-1 N/m2. The minimum value is the same for all, namely 1,000 x 10-30 N/m2. In the results of the displecement analysis, almost all of the changes in shape are the same. For the results of the first shelf stress analysis, the minimum value is 2,150 x 10-13 N/m2, the highest value is 7,111 x 10-5 N/m2. The middle shelf has a minimum value of 2.216 x 10-12 N/m2, the highest value is 6.838 x 10-5 N/m2. The bottom shelf has a minimum value of 1.738 x 10-13 N/m2, the highest value is 7.054 x 10-5 N/m2. In the results of the strain analysis, the best shelf is the middle shelf, because it has a smaller level of tension than the others. Keywords: Design, Analysis, Stress, Displacement, Strain.
