Abstract
The feasibility of milling of composite materials by abrasive waterjet is discussed, and the basic mechanism of chip formation, single-pass milling, double-pass milling followed by the repeatable surface generation by multiple-pass milling is studied. The major parameters affecting material removal rate are hydraulic pressure, standoff distance, traverse rate, and abrasive flow rate. Dimensional analysis shows these significant parameters in machining and the results are compared with the theory of material erosion. The single-pass milling tests of carbon/epoxy is then conducted. Also, the study extends to six-pass milling.
