The use of small high-velocity liquid jets under fluid pressure of 57,000 psi was investigated as a possible new method of machining wood with minimal material loss and tool maintenance. A variety of factors were studied in seven series of tests to ascertain the importance of related variables and to gain an insight to the mechanism of energy transfer during the cutting process. It was found that dense wood can be accurately machined to produce high-quality surfaces with a negligible loss of material. While there are limitations, it is felt the advantages associated with the process will justify its application for many operations.
