摘要:

为精确控制振动进给运动,研制了多参数可调的电解加工振动进给装置系统。通过对工具阴极振动进给方式对电解加工间隙内电解产物排出、电解液流场稳定性影响的分析,以剃须刀网罩上的微尺度阵列群缝的电解加工为研究对象开展了系列工艺试验,研究了振动进给的运动参数对微尺度群缝的平均缝宽、侧壁锥度的影响,据此优选了工艺参数,并成功批量加工出了缝宽为0.26mm、侧壁锥度小于5%的微尺度阵列群缝。试验结果证明,振动进给能够有效提高微尺度群缝的电解加工精度和加工过程稳定性。

Abstract:

A vibration feeding device system with multi-adjustable parameters was developed to precisely control the vibration feeding movement. By analyzing the influence of vibration feeding movement on the removal of electrolytic products in machining gap and the stability of electrolyte flow field and based on the machining of micro multi-grooves on razor grille, a series of experiments were carried out to study the influence of the vibration feeding parameters on microscale groove group's average width and sidewall taper. Finally, multi-grooves with width 0.26mm and sidewall taper less than 5% were batch processed with the optimum parameters. The experiments have proved that vibration feeding can effectively improve the machining accuracy and the machining process stability on ECM process in machining micro multi-grooves.

Key words: electrochemical machining(ECM), vibration feeding, multi-groove, micro scale, machining accuracy
