Study on the Two-Side Direction Burr in Grinding-Hardening Machine Based on Orthogonal Experimental Method

Abstract:

Based on the orthogonal experiment, this paper studied the influences of depth of cut ap, table speed vw and grinding method gm on the two-side direction burr in grinding-hardening machine. The results show that, with thermal-force coupling effect induced in the grinding-hardening machine, the metal in the workpiece’s surface flowed to two-side direction of the workpiece that without any constraint and leaded to the burr’s formation. The depth of cut ap and grinding method gm are significant factors that affected the size of two-side direction burr, and the significant order are as follows: depth of cut a_p> grinding method gm > table speed v_w >interaction av. With the increasing of depth of cut ap or the grinding trip, the max size of the two-side direction burr increased gradually; and with the raising of table speed v_w, the max size decreased firstly and then increased. In actual application, it should adopted the grinding parameters a_p＝0.2mm，v_w＝0.6m/min and up-down grinding to improve the quality of grinding-hardening and reduce the size of the burr.
