Our jet machining team offers the following suggestions when designing your part: Any 2D shape can be cut. Provide 2D CAD data of your part drawn to scale (1:1). Provide a detailed part print to be used by our Quality Controllers. Include tolerance on your part print. To reduce part cost, avoid sharp corners on parts. Sharp corners require additional machining time to produce. Minimum inside corner radius is 0.015" (0.381mm). Smallest hole diameter that can be cut is 0.030" (0.762mm). Thicker materials will require slightly larger minimum hole diameters. Surface finish is determined by the cut rate. A faster cut rate produces a rough surface finish & a low tolerance. A slower cut rate produces a smooth surface finish and high tolerance. more information If possible, supply a piece of scrap material for test cutting. Remember, water jet cutting is a cost effective way to rough out or create a near net shape part for use in another process. Water jet cutting is also a good way to locate and cut holes for secondary operations like tapping and reaming.
