报告摘要：

The aim of our research is to develop mathematical models of metal cutting operations, machine tool vibrations and control. The science-based digital models allow the virtual design, testing, optimization, monitoring and of control of machine tools and machining operations.

The model predicts the cutting forces, torque, and power consumed in machining parts by considering CNC system, material properties, cutter geometry, structural flexibilities, and cutting conditions along the tool path. The simulation system predicts chatter-free cutting conditions within the work volume of the machine tool or detects the presence of chatter vibrations along the tool path. The dynamics of servo drive control systems, and trajectory generation as a function of jerk, acceleration and velocity profiles of machine tools are considered in simulating the machine tool behavior along the tool path. An in-house developed virtual and real-time CNC system allows the design and analysis of any five-axis machine tool controller. Current research includes digital twin approach, where virtual simulation and real-time machine tool monitoring are integrated to achieve intelligent, self-adjusting machine tools.

The algorithms are published in the open literature and packaged in industrial software toolbox which can be used as a process planning tool by production engineers, or as an analysis and monitoring modules by industry.
