CAD/CAM Approach to Automation of the Production Process

This paper presents the application of Industry 4.0 in the production of machine parts using a CNC machine and an industrial robot. The functional structure of the flexible production cell, its configuration, programming methods and application in industry are explained in detail. The complete technology design was carried out using the ESPRIT software package, which involved selecting the processing system, introducing auxiliary accessories, selecting the required sequence of operations, defining the tool, defining the processing mode, creating the tool path, and generating the NC code for the CNC machine. With the help of a digital model of the machine (known as a digital twin), a controller emulator, machine parameters and a post processor, the system provides precise simulation and machine-optimized NC code. ESPRIT offers factory-developed post-processors for most types of machines and control units, which generate NC code without requiring subsequent modifications. It is also possible to create special post processors for special types of machines and applications. In this particular case, due to the work piece geometry and production speed, the 4 + 1 strategy was chosen on the 5-axis machine, involving the simultaneous movement of four axes and the indexical movement of one axis. Real-time machine CAM programming represents a fundamental change in the way tool paths are created, resulting in longer tool life, shorter cycle times and better machine utilization.
