An analysis of works devoted to the study and minimization of roughness on both horizontal and vertical surfaces grown at different angles to the construction platform was carried out. This study focuses on statistical processing using a correlation matrix of the results of the influence of the power, speed, and linear energy density (LED) on the roughness of vertically growing surfaces. To determine the influence of the LED value on the roughness of the vertical surfaces, four parameters were used: <i>Ra</i>, <i>Rz</i>, <i>Sa</i>, and <i>Sz</i>. The obtained results showed that, when using a certain value of the linear energy input, the vertical roughness <i>Ra</i> of the surface area of samples can be reduced from 15 to 2.5 µm.</p>","PeriodicalId":642,"journal":{"name":"Journal of Machinery Manufacture and Reliability","volume":"54 2","pages":"150 - 158"},"PeriodicalIF":0.4,"publicationDate":"2025-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143784168","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}
