The presented dependences allow one not only to determine the crimpling rate of the surface roughness at the time of joint formation, but also to limit the roughness rate to form the required contact area. Considering that <i>Ra</i> is standardized for critical surfaces of parts and <i>Rz</i> must be used to calculate the crimpling rate, the dependences for converting <i>Ra</i> to <i>Rz</i> are clarified. A comparative table is compiled confirming the correctness of the calculations in the range of <i>Ra</i> = 0.1–2.5 μm. Using the example of calculating and selecting a force fit, it is shown that different fits are obtained: ∅30<i>H</i>8/<i>y</i>8 with permissible values of surface roughness of the hole and shaft, and when using those specified in the drawing, ∅30<i>H</i>9/<i>z</i>9.</p>","PeriodicalId":642,"journal":{"name":"Journal of Machinery Manufacture and Reliability","volume":"54 2","pages":"159 - 166"},"PeriodicalIF":0.4,"publicationDate":"2025-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143784195","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}
