CNC machine laboratory stand with H-Bot parallel kinematics using the EtherCAT bus

Abstract

This paper presents an H-Bot kinematics machine control system. The H-Bot machine accuracy depends on the servo drives' synchronous operation and mechanical design. Therefore, the mechanical axes' movement quality is influenced by the communication bus and the ability to detect backlash and elasticity in the machine axes. EtherCAT – an industrial bus will be used for communication between the controller and other machine control system elements. Each mechanical axis at the H-Bot machine is equipped with a position measurementsystem. The laboratory stand was equipped with accelerometers. It is planned to perform research in the Predictive Maintenance and Trajectory Optimization field.
