However, the milling efficiency is limited because the ultrasonic vibration toolholder ER16 collet has a critical cutting speed. Thus, a 2D UVAM platform is built to ensure precision machining efficiency and improve the surface quality without changing the milling toolholder. To evaluate this 2D UVAM platform, ultrasonic-vibration-assisted high-speed dry milling (UVAHSDM) is performed to process a titanium alloy (Ti-6Al-4V) on the platform, and the milling temperature, surface roughness, and residual stresses are selected as the important indicators for performance analysis. The results show that the intermittent cutting mechanism of UVAHSDM combined with the specific spindle speed, feed speed, and vibration amplitude can reduce the milling temperature and improve the texture of the machined surface. Compared with conventional milling, UVAHSDM reduces surface roughness and peak-groove surface profile values and extends the range of residual surface compressive stresses from −413.96 MPa to −600.18 MPa. The excellent processing performance demonstrates the feasibility and validity of applying this 2D UVAM platform for investigating surface quality achieved under UVAHSDM.</p></div>","PeriodicalId":7342,"journal":{"name":"Advances in Manufacturing","volume":"12 2","pages":"349 - 364"},"PeriodicalIF":4.2,"publicationDate":"2024-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139515028","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The cutting tests were performed on a sawing platform under lubricated conditions. Models of the sawing arc length and working sawtooth cutting force variations were developed for sawing steel pipes, and the accuracy of the sawing force model was verified experimentally. The results indicate that the variations in the sawing force are proportional to the sawing arc length. The circular saw blades with microtextures that did not penetrate the sawtooth rake face exhibited the lowest cutting force, sawing noise, and highest machined surface quality. Furthermore, the worn-out distance of the rougher and finisher sawteeth was reduced by approximately 7.4% and 44.1%, respectively, compared with conventional circular saw blades. The main failure modes of sawteeth were tip wear, rake face adhesion, and oxidative wear.
