Moreover, because the support material is easily removed by thermal treatment, it results as an additive process able to guarantee very high level of shape complexity. Nowadays, thanks to new commercial polymers able to withstand higher temperatures, this technology starts to find applications in the production of insert mould for injection moulding process. The authors present a study about the thermo-fluid dynamics behaviour of samples of inserts mould having conformal cooling channels. The mould heat transfer performances were tested via experimental and numerical techniques. Results suggest that for the prediction of the transient thermal behaviour of these new polymers, it is quite important the accurate evaluation of material thermal properties. For the design based on numerical approaches, challenges could arise from the wide range of variations found on thermal properties.","PeriodicalId":39429,"journal":{"name":"International Journal of Mechatronics and Manufacturing Systems","volume":"270 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135495529","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}

Their influence on process signatures also makes AM processes not fully manageable creating unacceptable levels of inconsistency. To detect the fusion quality with a purpose of quality predictions, in-situ process sensing and monitoring with sensors is often utilised with the goal that AM process can be controlled for consistency in quality. This paper provides a review of the literature on in-situ process sensing and monitoring methods and discusses research challenges and future directions for further efforts. Currently, sensory data is used for data analysis and making mostly off-line quality quantifications and predictions. The future goal is to develop intelligent AM systems that use in-situ process data for making automated intervention and quality control decisions.","PeriodicalId":39429,"journal":{"name":"International Journal of Mechatronics and Manufacturing Systems","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135495536","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}

Unlike sheet metal stamping, SPIF does away with costly forming dies but instead uses a tool to incrementally form the sheet into the desired geometry. However, a key weakness of SPIF is its poor geometric accuracy, which is largely caused by material spring-back throughout the forming process. This paper presents a framework which minimises SPIF geometric error through optimisation of the forming toolpath. The approach utilises a trained convolutional neural network (CNN) to model the forming process, which provides greater flexibility and compatibility with a wide range of geometry. A geometric compensation algorithm was developed to compensate for the predicted spring-back. Experimental validation of the proposed framework demonstrated consistent accuracy improvements in both trained and untrained geometry. This paper highlights the viability of using CNNs in improving SPIF accuracy.","PeriodicalId":39429,"journal":{"name":"International Journal of Mechatronics and Manufacturing Systems","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135495317","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}
