用数控线切割机加工精密平板凸轮,必须求出线切割机钼丝中心的轨迹。这一轨述与凸轮的实际轮廓同样是理论轮廓的包络曲线。当然,它们的滚圆半径不同。实际轮廓的滚圆半径r等于从动件滚子半径;而钼丝中心轮边的滚圆半径d则等于从动件滚子半径减去钼丝中心与实际轮廓的距离,如图1所示。它们的求解方法是相同的。为方便叙述,下面把它们统称
CNC cutting machine with precision flat cam, you must find the wire cutting machine molybdenum wire center of the track. This is the same profile as the actual profile of the cam. Of course, they have different rounded radii. The radius r of the actual profile is equal to the radius of the follower roller. The radius d of the wheel rim at the center of the molybdenum wire is equal to the radius of the follower roller minus the distance between the center of the molybdenum wire and the actual contour, as shown in FIG. 1. Their solution is the same. For the convenience of narration, they are collectively referred to below
