PROBLEM TO BE SOLVED: To provide machining device and method for quickly and exactly forming a pyramid recessed part on a surface of a workpiece. SOLUTION: A base part 2 is mounted on a machining machine body 1 or a tool rest 12 to guide a cutter support body 3. A linear motion mechanism 4 is provided between the cutter support body 3 and the base part 2. A cutter 5 is mounted at a distal end of the cutter support body 3. In the cutter 5, a cutting edge at the distal end is formed into a V-shape and plane cutting is performed by the V-shaped distal end and both edges. COPYRIGHT: (C)2011,JPO&INPIT
