傾斜切削による無電解Ni-Pめっき金型の表面粗さの改善

Ultraprecision aspheric cutting process using a monocrystalline diamond tool is widely used in the manufacturing of optical components and their molds/dies. Plastic lenses are molded by injection molding an amorphous electroless Ni-P plated molds/dies decreasing lens surface roughness required. Generally, oblique one methods to decrease force burr, roughness. In this study, was applied mold materials experiments, plunge cut molds, aluminum, oxygen free copper, brass clarify burr behaviors. Finally, flat diamond-turned changing angle tool, evaluated, effects were evaluated.
