电化学放电加工是一种新兴的加工方法,适用于玻璃等非导电材料的微细加工。ECDM是一种混合工艺,其中材料去除涉及化学和热机制。各种工艺参数影响电火花加工的性能。不适当的ECDM工作条件可能导致玻璃加工中不期望的表面损伤。研究了硼硅酸盐玻璃电火花加工过程中,由于化学机制引起的表面起皱和由于热机制引起的表面裂纹的消除方法。发现在酸性环境中的ECDM避免了在玻璃加工中由化学蚀刻引起的表面起皱。此外,当用混合电解质进行ECDM时,热损伤和化学损伤都得到减轻。
Electrochemical discharge machining (ECDM) is an emerging method suitable for the micromachining of nonconductive materials such as glass. ECDM is a hybrid process in which material removal involves both chemical and thermal mechanisms. Various process parameters affect the performance of ECDM. Improper ECDM working conditions may lead to undesirable surface damages in glass machining. This paper investigates the methods to mitigate surface wrinkle formation caused by the chemical mechanism and surface cracks caused by the thermal mechanism in the ECDM machining of borosilicate glass. ECDM in an acidic environment was found to avoid surface wrinkling caused by chemical etching in glass machining. Moreover, both thermal and chemical damages are mitigated when ECDM was performed with a mixed electrolyte.
