Designing for Waterjet and CNC Machining Combination
In the competitive landscape of custom part manufacturing, leveraging the strengths of different processes is key to achieving superior results in both efficiency and quality. Combining Waterjet Cutting with CNC Machining offers a powerful, synergistic solution for producing complex components, especially for batch production runs. Understanding how to design for this hybrid approach from the outset can unlock significant benefits for your projects.
Waterjet cutting utilizes a highpressure stream of water mixed with abrasive to slice through materials. Its primary advantages are the absence of heataffected zones (HAZ), the ability to cut virtually any material, and minimal material waste. It excels at quickly cutting out the overall profile of a part from a large sheet or plate. CNC machining, on the other hand, uses rotating cutting tools to achieve highprecision features, tight tolerances, excellent surface finishes, and complex 3D geometries.
The true power lies in using each technology for what it does best. A welldesigned hybrid process begins with the waterjet, which efficiently handles the "roughing" stage. It cuts the part's primary outline and large internal cutouts from a raw plate, a much faster and more costeffective method than milling away excess material on a CNC machine. This preformed blank is then moved to a CNC mill or lathe for the "finishing" operations. Here, critical features are added: precision holes with tight tolerances, threaded taps, intricate pockets, and finely finished surfaces.
To effectively design for this combination, engineers should consider the following:
1. Separate the Features: Clearly define which part features are best suited for waterjet and which require CNC machining. Use the waterjet for the overall silhouette and large openings. Reserve CNC for precision bores, threads, and detailed 3D contours.
CNC machining 2. Incorporate Fixturing Tabs: Since waterjetcut parts are fully separated, small tabs can be left to hold the part within the stock plate. These tabs are easily removed during the CNC finishing process, providing a builtin fixturing solution.
3. Account for Kerf and Accuracy: Waterjet leaves a small kerf (cut width). Designers must account for this, typically by leaving a small stock allowance (e.g., 0.51mm) on edges that will be finishmachined. This ensures the CNC process can achieve the final dimension and a clean edge.
4. Material Selection: This hybrid method is exceptionally versatile, working perfectly with metals like aluminum, stainless steel, and brass, as well as plastics and composites.
