Abstract

Abrasive Water Jet (AWJ) cutting is at the forefront of current alternative machining operations with applications in as diverse industries as defense, biomedical, and aerospace. These industries make many demands of the manufacturing processes they employ by specifying materials that are traditionally difficult to work with and requiring tolerances in the 10 micron range or less. The AWJ cutting process is particularly adept at meeting these demands by the nature of the cutting action and the mechatronics of the machine control. AWJ cutting utilizes the momentum transfer from a high-pressure water jet to abrasive particles which impact the target material. The objective of this research project is to design and construct a micro-scale CNC AWJ cutting machine capable of cutting 5 mm thick carbon fiber sheets. The aspects of engineering that are required to realize this project are numerous and diverse. Three goals of this project are to 1) simulate the fluid dynamic behavior of the AWJ cutting process with CFD tools, 2) model the machine tool with CAD, and 3) verify the accuracy of the models with the measured performance of the actual machine. This research includes the design and construction of both an electronic control system capable of translating CAD geometry into machine language, i.e. G-code, and the interface of the machine control elements and electronics. The AWJ system is capable of cutting glass and ceramics up to 10 mm thickness with a resolution of 0.0003” and accuracy of 0.0003” with a repeatability of 0.0003”. Waterjet machine traditionally cost in the range of $100,000 and above, but the proposed waterjet machine in this study only cost less than $5,000 which makes it more affordable.
