Tolerance analysis of surface-to-surface contacts using finite element analysis
Paper in proceeding, 2018

The accuracy of a cutting tool is dependent on the surface-to-surface contact between the tool body and the insert. Depending on the application, the forces generated during a cutting operation will change in both magnitude and direction. This will alter the contact locations between the tool body and carbide insert thus affecting on both tool life and key characteristics such as cutting performance and productivity. In this article, a methodology is presented to analyse contact variation in the interface between the tool body and the carbide insert. Results presented in this paper can be used for tolerance allocation of surface-to-surface contacts.
