Coining of Thin Plates to Produce Micro Channel Structures been used to produce rib type channel structures with 0.4 mm width of the ribs as well as of the channels. The remaining thickness at the channels is about 0.3 – 0.6 mm, depending on the initial sheet thickness. The experimental results are compared to finite element simulations.

Manufacture of Aspherical Fresnel Lens with Ideal Cross-sectional Profile with Oxygen-free Copper an0 μm on an oxygen-free copper and an acrylic resin plate. The result showed an ideal lens groove with the surface roughness of 8 nm(P-V). The accurate focus of 100 mm was also confirmed by the optical assessment with a manufactured acrylic fresnel lens.

Dry Cutting of Stainless Steel Using Indexable Inserts Having Self-heat Absorbing Capabilityting method using this cutting tool is proposed. As a result of cutting experiments using stainless-steel workpieces, in the case of the proposed dry cutting method using this insert, the tool life can be improved to more than twofold that in the case of the dry cutting using a conventional tool.

Three-dimensional Micro-forming Process of Thin Film Metallic Glass in the Supercooled Liquid Regionture. Moreover TFMG soften in a certain temperature range called the supercooled liquid region, which makes it easily be formed into three-dimensional shapes. In this paper, new three-dimensional microforming process of TFMG in the supercooled liquid region and its application for micro actuator are reported.

Influence of Micro Machining on Strength Degradation of a Silicon Nitride Ceramicmicro machining on the strength degradation. Dimpling by LBM can not be prevented from forming a sharp edge around the dimple, which may degrade the strength of the ceramic. The AJM dimple has a smooth-faced rounded shape, and only negligible deterioration of the strength takes place.
