摘要
提出了两轴联动磨削陶瓷刀片的方法,并给出了典型刀片数学模型的推导过程.磨削刀片过渡圆弧时,过渡圆弧的回转中心到砂轮面的距离必须恒等于过渡圆弧的半径,磨削过渡圆弧的复合运动要保持过渡圆弧的回转中心沿平行于砂轮面的直线运动;刀片的回转中心沿垂直于砂轮面的直线运动.根据该复合运动推导出各种刀片过渡圆弧的数学模型.所开发的陶瓷刀片数控加工系统,可以对不同形状的陶瓷刀片的周边进行磨削加工,这种加工方法具有较强的柔性生产能力和更高的生产效率.实际生产表明,用此方法加工的刀片精度非常高,完全能满足设计的要求.
The method of grinding oxide tool with two axles is presented and the mathematical models for some typical oxide tools are deduced. When the transition arc is ground the distance between the gyration center of the transition arc and the surface of the grinding wheel must be equal to the gyration radius of the transition arc identically. The combined motion of grinding the transition arc maintains that the gyration center of the arc moves along the parallel line to the surface of the grinding wheel, and the gyration center of the oxide tool moves along the vertical line to the surface of the grinding wheel. According to the combined motion the mathemetical models of the transition arcs for all oxide tools can be deduced. The numerical control system for grinding oxide tools can grind the periphery of various oxide tools.The grinding method is more flexible and efficient. It has been proved in the production that the precision of oxide tools ground by this method is very high and meets the design demand perfectly.
