A Novel Concept of CNC Machining Center Automatic Feeder

Abstract

Machining operations are extremely relevant in the current metalworking scenario. Many efforts have been made by researchers in order to optimize machining trajectories and automatic machine feeding systems. However, only the large companies with huge productions have capacity enough to invest in sophisticated feeding systems. This project intends to present a solution to extend the autonomy of machining centers by using a 6-axis robot to replace the operator on work piece feeding operation. The system consists in a robot embedded in the same structure as a small warehouse positioned on one side of the machine, maintaining the possibility of operating in a standard manner. With the modular construction of the warehouse it is possible to accommodate numerous work piece sizes and engraving a Quick Response code at the work piece holder allows its identification and therefore brings flexibility to the system. It is expected that a milling machine equipped with this system present an extended working capability without human intervention, becoming possible to extract more useful process control information, in line with the Industry 4.0 needs.
