Study on micro plastic deformation by cutting and forging system from a fiber

在微细加工领域，传统的加工方法如切割和锻造被广泛应用。为此，研制了由压电致动器、微工具、微力传感器、带微针的微手和手动平移装置组成的微动装置。利用这些单元，构建了微型切割机、微型锻压机和微型搬运系统等微加工设备。所有这些装置都是制作成小尺寸的，放在光学显微镜的舞台上。进行了以下实验：(1)微锻法：用微手夹紧直径50微米的纤维，用切割机切割。显微切割：对直径300微米的纤维进行夹持和旋转。用微型刀具将试件切割成直径为20微米。(3)微操作：用两只面对面的微手来夹持和排列50微米大小的微小零件。通过这些实验，证实了机械加工方法也适用于微加工领域。传统的切割和锻造方法可用于制造微小零件。进一步的精密加工和微细加工是未来的需要。

Traditional machining methods such as cutting and forging are applied in the micro machining world. For this purpose, micro translation unit using piezo actuator, micro tool, micro force sensor, micro hand with micro needles and manual translation unit have been developed. Using these units, micro machining equipments such as micro cutting machine, micro forging machine and micro handling system have been constructed. All of these apparatuses are made in small size to be set on the stage of optical micro scope. Following experiments have been made ;(1) Micro forging : A fiber 50 mu m in diameter is cramped by micro hand and cut by a cutter. Then the specimen is translated by micro hand and forged by a punch.(2) Micro cutting : A fiber 300 mu m in diameter is chucked and rotated. The specimen is cut by a micro cutting tool to the diameter of 20 mu m.(3) Micro handling : Two facing micro hands are operated to hold and arrange micro parts of 50 mu m size.Through these experiments, it is confirmed that mechanical maching methods are also useful for the micro machining world. Traditional cutting and forging method are available to make a micro parts. Further precision machining and further micro machining are necessary for the future.
