Proposes to enable a CNC mill from 3 axes to 5 axes synchronized

摘要

This paper proposes a methodology for enabling a 3 axes Mill CNC machine to work in a synchronized operation with 5 axes. Different alternatives for communicating the fifth axis were analyzed, as using a TRT-160 with a microcontroller and an analog multiplexer. Another option could be done by using a CNC via serial bus and a Microcontroller digital I/O ports, passing the code through a converter code, replacing some command lines and directing the additional axis instructions to the servomotors via RS-232 serial bus to generate displacement on the servomotors that emulates the fourth and fifth axis. It could achieve synchronization of two conventional servomotors with a HAAS VF-2 Mill Machine that opens the possibility for evaluating six o more axes movement related to a complex machining process, as well as connecting a robotic arm or a conveyor belt in a manufacturing cell.
