摘　　要：针对铁电功能材料硬度低、脆性大、易破损、加工效率低,很难满足高效超精密加工的要求的问题,选取了三硼酸锂、硫化锌、硒化锌、碲锌镉等几种典型铁电材料,通过调研国内外最新的研究成果,对其加工原理、方法等进行了深入的分析研究。研究结果表明:随着游离磨料研抛、固结磨料研抛、单点金刚石超精密车削、数控抛光等技术广泛应用于铁电材料的加工中,铁电材料的面型精度、表面质量和加工效率得到了进一步的提升,其应用前景看好。Aiming at the problem that ferroelectric functional materials has many scarcities in the aspects of low hardness, extreme brittleness, easy breakage,low processing efficiency,difficult to meet the requirements of high efficiency and ultra precision machining, the typical ferroelectric materials i.e. lithium triborate, zinc sulfide, zinc selenide and cadmium zinc tellurium were selected to make a deeply analysis on the machining principle and methods of themselves via the available research result from domestic and abroad. The results indicated that the profile accuracy, surface quality and machining efficiency of ferroelectric materials have been sudden improved with the application of lapping-polishing method for free and fixed abrasive, single point diamond turning(SPDT) and ultra-precision fly cutting, their application prospect have been obviously promoted.
