To solve these disadvantages, some measures must be taken to shorten and simplify the technologic process, to reduce the costing, to use new materials to modified PLA, and to enhance fibers’ strength [7].
It can be used as the basic stuff of biomedical materials, cell culture media, implanting organ and micro millimeter-level filter materials.

Introduction Micro ultrasonic machining (micro USM) is the rationalized version of the ultrasonic machining process which is popular for machining of hard and brittle materials such as silicon, glass and ceramics.
In order to minimize tool wear, tools should be constructed from relatively ductile materials such as stainless steel, brass and mild steel [5].
