Abstract
The study has developed a new machining process for the side seal components of gray cast iron alloy of rotor engine, which is different from the traditional WEDM (wire electrical discharge machining) process. The new manufacturing process (milling + grinding process) will save 78% of the cost and 83% of the time for making each side seal component, and the accuracy of the average surface roughness of the component will be 2.1 times that of the traditional manufacturing method. If the components are polished with a self-made polishing rod, the accuracy will be increased by almost 20 times compared with the new manufacturing process.
