LN is a kind of pyroelectric material.
To solve these problems, we choose glass grinding plate to decrease grinding pressure; we must also choose the small hardness and good morphology abrasive as polishing materials.
When the pyroelectric materials absorb infrared radiation, its temperature will have a small change and so does its spontaneous polarization.

Introduction In recent years, ECM has received much attention in the fabrication of micro parts because of its many advantages such as no tool wear, stress free and smooth surfaces of machined product and ability to machine complex shape in metal materials, regardless of their hardness [1].
It is difficult to machine macro- and micro-holes in very hard and brittle materials by using traditional machining methods.
The material of workpiece is stainless steel 304.
