【摘要】:針對氮化硅陶瓷回轉曲面零件高效低損傷的加工要求,設計適用于回轉面加工的在線電解修整(ELID)磨削實驗裝置,在數(shù)控坐標磨床上進行預修銳實驗。基于平行電極電解池模型,建立預修銳時間與氧化膜成膜厚度的關系模型,分析占空比和極間間隙對成膜效果的影響規(guī)律。結果表明:工藝參數(shù)對預修銳時間的影響程度依次為占空比電解液流量砂輪轉速脈沖頻率。采用田口方法獲得最優(yōu)工藝參數(shù)組合為占空比0.75,脈沖頻率50kHz,砂輪轉速9 000r/min,電解液流量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.
