MEW showed stable milling without chattering at higher feed, improving the machining efficiency by 150%. No chattering and more stable milling is possible with MEW. Burrs are prevented and excellent surface finish is achieved. Despite the milling difficulty because of the properties of the material (42HRC), PR1525 kept good cutting edge form, minimizing wear and adhesion.
