---Welcome to MMMT2021----
2021 International Conference on Machining, Materials and Mechanical Technologies (MMMT2021) will take place in Shanghai, China during March 29-30, 2021. It will provide a platform for educators, scholars, managers and graduate students from different cultural backgrounds to present and discuss research, developments and innovations in their academic fields. Sincerely welcome prospective scholars to submit their novel research or technological contributions to MMMT2021 and share their valuable experiences with other scientists and students from all over the world.

---Paper Publication-----
Papers submitted to MMMT2021 will be reviewed by technical committees of the conference. All accepted and registered papers will be published in the Journal of Materials Science Forum [ISSN print 0255-5476, ISSN web 1662-9752]. And the press will submit all papers to major databases such as EI Compendex, Scopus, SCImago Journal & Country Rank (SJR), Inspec, Cambridge Scientific Abstracts, ProQuest, EBSCO, WorldCat, Google Scholar, and CNKI Scholar and so on. We sincerely invite you to join MMMT2021, and welcome your submitting. For a few authors who don't expect any publication of your papers, you're welcome to submit the abstracts to us which will be sent to at least two technical committees for a brief review, and present your abstract at the conference without publishing.

----Paper Submission-------
