A study of bifurcation behaviour in oblique turning operation

Analysis of the tool tip radial stiffness of turn-milling centers

“…It presents many sources of manufacturing errors such as workpiece deflection, non-infinite stiffness of the tool-machineworkpiece system, unknown initial geometry of the raw part, thermal deformations, vibrations of the machine system, and tool wear among others [3]. There were a variety of efforts focused on reduction of errors, including robust drive compensation [4], preload assessment for spindle assembly [5], different techniques for turning of low machinability materials [6], dynamical analyses to identify process vibration sources [7,8], and the introduction of composite materials in machine design to improve of the quasi-static and dynamic performance [9]. However, the machine end-user often ignores the nature and magnitude of these sources of error, which are usually hard to measure and account for.…”
