Experimental Study on Process Parameters of High-Speed Micro-Milling Al₂O₃ Ceramics

Abstract:

Al₂O₃ ceramics are widely used in aerospace, defense industry, microelectronics industry and many other fields, but the precision machining methods of this material are restricted because of the high hardness. Therefore, this paper makes an orthogonal experiment of high-speed micro-milling Al₂O₃ ceramics by machining full-diameter micro-grooves. The feasibility of micro-milling Al₂O₃ ceramics with diamond coated tools is verified. In the experiment, surface roughness values obtained are treated as evaluation indexes. And the influences of many process parameters on the workpiece surface roughness are analyzed by range analysis method. These parameters are spindle speed, feed rate and axial depth of cut. Then optimized the process parameters and obtained a set of suitable parameters to micro-mill Al₂O₃ ceramics.
