The purpose of the paper is to design, model, and analyze a feasible, more sustainable impact absorbing structure. There has been continuous development in the field of space science and aerodynamics, which has led us to encounter a lot of challenges. One of such challenges is smooth landing of objects. We started by creating tessellations with the help of Miura ori fold to get a repeating structure of the TCO (Triangulated Cylindrical Origami) with an aim to create a general-purpose design for Impact absorbing applications. A comparison between origami TCO’s sheets, hexagonal sandwich sheets, and cardboard corrugated sheets was made. The TCO cells are better at absorbing energy absorption due to their physical structure. The result shows that the Origami TCO sheets exceed the traditional honeycomb and corrugated sheets. As the model we developed is a general-purpose design, it can be upscaled or downscaled depending on its required application, which can range from nano technology to space technology.","PeriodicalId":53274,"journal":{"name":"Journal of Engineering Project and Production Management","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70054836","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To enhance our understanding of the field of machining and its applications, a comprehensive literature assessment on machining steels using nanofluids with/without the minimum quantity lubrication (MQL) approach was conducted. This research aims to investigate the performance of nanofluids (n-Al 2 O 3 , n-MoS 2 , and n-graphene) mixed with coconut oil in various proportions and injected into the tool–work interface using the MQL mist system. Output responses, such as surface roughness values, and cutting temperatures, were measured. The cutting temperatures were determined using an infrared camera and a k-type thermocouple, and the surface roughness was determined using a Talysurf surface meter. Cutting parameters, such as cutting speed, feed rate, and depth of cut, were maintained constant throughout the experiments. The experiments comprised a single factor (MQL fluid) with eight levels. Multiresponse optimization using grey relational coefficients showed that n-Al 2 O 3 and n-MoS 2 hybrid combinations with coconut oil yielded better results, i.e., higher ranks, compared with n-graphene mixtures in coconut oils. The experimental findings demonstrated that nanofluids outperformed pure coconut oil. Nano-Al 2 O 3 combined with coconut oil produced a superior surface finish, lowered the cutting temperatures, and ensured minimum chip thickness.","PeriodicalId":53274,"journal":{"name":"Journal of Engineering Project and Production Management","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70054442","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
