【摘要】 根据断裂设计原理，给出了棒料上预制Ｖ型切口的最佳参数。进而介绍了一种用于在圆棒料上切制环形切口的切槽机。其特点是将国棒料固定，切槽刀随主轴刀盘回转的同时作径向切削运动。更多还原

【Abstract】 The optimum parameters for V-shapedgroove precut on bar are given on the basis of brokendesign principle. A grooving machine is developed tocut ring groove in round bar. The round bar to be cutis fixed and the grooving tool is rotating with spindle,in the meantime, the tool is fed in radially.更多还原
