Waterjet cutting has not traditionally been thought of as the “lowest cost” manufacturing process, but, depending on the situation it can be.
Part nesting: One such instance where waterjet cutting can reduce costs is through part nesting. If your part design can be nested in such a way that waterjet cutting allows us to produce more parts from the same size sheet of material, then it can reduce material costs significantly.
Layering: Waterjet cutting can provide the most layering benefits of any process. It is possible to layer multiple sheets of material on top of each other and cut multiple parts out at a time. Because a waterjet can handle a greater level of thickness overall, it can typically cut through more layers than a steel rule die.
