Implementation of a cutting forces model through virtual simulation of machining process

This paper presents the development of a methodology for monitoring the part machining process on CNC machine tools using a virtual machine model in the MATLAB/Simulink environment. The focus is on monitoring the components of cutting forces that occur during the milling process. A vertical milling machine was used for model validation. By integrating the existing cutting force model and the virtual machine model in MATLAB/Simulink, the visualization of real-time cutting force values, which depend on the change of the current engagement map along the programmed toolpath, is enabled. The development of the presented simulation environment forms the basis for the implementation of new functions in G-code, contributing to the stability and optimization of the machining process.
