Cutting methods and cutting apparatus

摘要

The present invention provides cutting methods and cutting apparatus that can precisely cut workpieces in complicated shapes with high aspect ratios regardless of materials of the workpieces. The present invention is cutting methods and cutting apparatus using a wire saw wherein cutting processing is performed for a workpiece by extending a cutting wire on a cutting arm that rotates around a wire's center axis or a real cutting position relative to a fixed section and rotating the cutting arm such that a cutting direction of the wire matches a support direction of a total stiffness that supports the wire.
