Design of a Monitoring System for CNC-Machining Processes

Presented at Advancements in Sustainable Manufacturing Practices

Data collection and visualization is a key enabler technique in the Industry 4.0 era. This paper describes a senior project that designs a monitoring system for manufacturing processes. It deploys multi-heterogeneous sensors for cutting force and vibration to monitor CNC machining processes. Students were trained to understand the working principles of sensors, data acquisition (DAQ) devices, programming, and data analysis. The development work includes: 1) part design and manufacturing process design in Siemens NX; 2) prototype the part using CNC machining; 3) integrate sensors and the DAQ system; 4) LabVIEW programming using field-programmable gate array (FPGA) and real-time techniques; 5) experiment to test the monitoring system and acquire data; and 6) digital signal processing and analysis on the experimental data. This work can support ABET accreditation for Virginia State University’s Manufacturing Engineering Program particularly for the Student Outcome of “an ability to develop and conduct appropriate experimentation, analyze and interpret data, and use engineering judgement to draw conclusion.”
