摘要 针对非导电工程陶瓷的加工难题,提出了双电极同步伺服电火花磨削新方法,并用不导电的Al2O3工程陶瓷进行了加工实验,研究了脉冲宽度、脉冲间隔、峰值电压、峰值电流等电参数对材料去除率和表面粗糙度的影响规律,并进行了理论分析。实验结果表明,在实验加工的范围内,脉冲宽度的增加、峰值电压的升高、峰值电流的增大、脉冲间隔的降低都能使材料去除率升高,而对表面粗糙度的影响则不尽相同。 A new method known as electrical discharge and grinding with synchronous servo double electrodes (EDGSSDE) is presented in this paper for nonconductive engineering ceramics, and experiments have been carried out with insulating Al2O3. The effects of electrical parameters such as pulse width, pulse interval, peak voltage, peak current on the material removal rate (MRR) and surface roughness (Ra) are researched, and the mechanism is analyzed. The results show that higher MRR can be gained with increasing pulse width, peak voltage, peak current or decreasing pulse interval, but no rule to surface roughness.
