圆球车削公差控制与刀补运用

The ball truning tolerance control and tool offset usage

车削圆球时,刀具R的正确性,对刀的精确度,机床运动精度都将影响球面的几何精度。为了较好地控制球的圆度,在半精加工时,即未加工到最终尺寸时,应测量球的圆度,以便调整。这就要求加工余量均匀,刀具轨迹为同心圆,阐述了对车削圆球时公差控制、刀补应用提出几种方法。

When cut the ball with the lathe, the accuracy of the tool nose radius, the accuracy that coordinates set and the lathe running accuracies will effect the sphere accuracy. For controling the circle degree of the ball betterly, at the semi finish, should measure the circle degree of the ball, for the purpose of correction. This will beg the part stock blance, the track of tool are concentric circles.
