Prototype Wireless Controller System Based on Raspberry Pi and Arduino for Engraving Machine

Abstract

This paper aims to explore the theories and techniques behind procedures of wireless controller system for mini CNC milling machine. The developed controller enables the machine tool to be controlled based on wireless communication and NC data generated from CAD/CAM systems. Then, a computer vision component using a web camera is proposed for the NC machine tool monitoring. It is explained the position on the machining table. This newly designed wireless controller system can be widely used in electrical and medical industry for making small parts and engraving small features. Fabricated prototype wireless controller system was calibrated and tested under various self-testing procedures to meet industrial standard. Comprehensive cost analysis and profit estimation was conducted after completion of the prototype.
