摘要:3J33B maraging steel is a high-strength steel which is used for fabricating precision elastic components. In this paper, experiments were carried out to investigate chip formation, surface roughness, and top burr formation in micro end milling of 3J33B from an energy perspective. Chip formation and surface roughness in the centerline position of the slots were analyzed based on the average specific cutting energy. Surface roughness and burr size of the two sides of the slots were compared to the variation of the instantaneous specific cutting energy in a half cutting revolution. It was found that the chips became more fragmentized with an increase in the specific cutting energy due to the plowing effect. The formation of the down-milling side required more specific energy than that of the up-milling side. It was proven that the increment of the specific energy on the down-milling side was related to the better surface finish and greater size of top burrs. At last, some suggestions on parameter selection for surface improvement were proposed according to the research results.
