Design and Development of a Modular Automated Pallet Changing System for CNC Machining Centres
Abstract:
The main objective of the developed automated pallet changing system is to increase the productivity of CNC machining centres and to minimize machine idle times. The system’s core component is a loading unit equipped with two independently controlled forks, enabling fast and precise pallet handling while significantly reducing non - productive time. The entire structure is modular and fully electrically driven, utilizing linear actuators and servo motors that ensure high positioning accuracy. The design and verification of the structure were performed using the Finite Element Method (FEM) to guarantee adequate rigidity and operational reliability. The innovative semi-circular pallet storage provides higher capacity and a more compact layout compared to conventional linear storage systems. Additionally, a rotary loading station was introduced to further reduce setup and handling times. A functional prototype was produced using additive manufacturing with PLA material and is controlled by an Arduino-based system, demonstrating the feasibility of the concept. The developed system is currently under patent protection in Slovakia, confirming its industrial applicability and technological originality.
