Read full description

The CNC milling machine simulator is a multimedia application designed to provide a basic introduction to beginner mechanical engineering professionals with the principles of programming operations for milling parts using a standard (ISO) G-code. The main task of the application is syntactic analysis (parsing) of the code of control programs in order to build a graphical model of cutting tool trajectories in three-dimensional space. The main functions of the application: editing the code of the control programs of the milling machine, operations with files of control programs, setting the geometric parameters of the cutting tool, continuous/step-by-step execution of blocks of control programs, three-dimensional visualization of tool movements in the working space of the machine, simplified visualization of the machined surface of the part, calculation of processing modes, a quick reference guide to using G-code. The main limitations of the application are: low accuracy of cutting surface modeling, the impossibility of using polygonal geometry as a workpiece, a simplified model of machine tooling elements.
