【摘要】：针对氮化硅陶瓷回转曲面零件高效低损伤的加工要求,设计适用于回转面加工的在线电解修整(ELID)磨削实验装置,在数控坐标磨床上进行预修锐实验。基于平行电极电解池模型,建立预修锐时间与氧化膜成膜厚度的关系模型,分析占空比和极间间隙对成膜效果的影响规律。结果表明:工艺参数对预修锐时间的影响程度依次为占空比电解液流量砂轮转速脉冲频率。采用田口方法获得最优工艺参数组合为占空比0.75,脉冲频率50kHz,砂轮转速9 000r/min,电解液流量1.0L/min。
[Abstract]:In order to meet the requirement of high efficiency and low damage for silicon nitride ceramic rotary surface parts, an on-line electrolytic dressing (ELID) grinding experimental device is designed for machining rotary surfaces, and the pre-dressing experiment is carried out on the NC coordinate grinder. Based on the model of parallel electrode electrolytic cell, the relationship between pre-dressing time and the thickness of oxide film is established, and the influence of duty cycle and gap between electrodes on the effect of film formation is analyzed. The results show that the degree of influence of process parameters on pre-dressing time is duty cycle electrolyte flow wheel speed pulse frequency in turn. By using Taguchi method, the optimal process parameters were obtained as follows: duty cycle 0.75, pulse frequency 50 kHz, wheel speed 9 000 r / min and electrolyte flow rate 1.0 L / min.
