The present study explores the design of an effective process chain that combines micro Abrasive Waterjet (micro-AWJ) and micro Wire Electro Discharge Machining (micro-WEDM) technologies. An experimental spring component is chosen as leading test case, since fine geometric features machining and low roughness on the cut walls are required. The advantages deriving from the two technologies combination are discussed in terms of machining time, surface roughness and feature accuracy. First, the performance of both processes are assessed by experimentation and discussed. Successively, different process chains are conceived for realizing two test cases with different size, displaying the advantages and drawbacks of the combinations.
