<p>PROBLEM TO BE SOLVED: To provide a workpiece cutting processing technology capable of processing a workpiece made of soft and hard materials well, reducing facility costs, and reducing the number of processing steps.SOLUTION: A composite cutting blade tool 10 is raised in an arrow direction (2) and, as indicated by (c), the tip of a soft material cutting blade 15 is moved to the height of a processing surface 35 (composite blade tool moving step). The composite cutting blade tool 10 is moved in an arrow direction (3). As indicated by (d), by moving the soft material cutting blade 15 through the processing surface 35, a deposit 40 abuts on the end of the processing surface 35 to drop from the tip of the soft material cutting blade 15 in an arrow direction (4) (passing step). The deposit 40 at the entire tip of the soft material cutting blade 15 is removed. Thus, appropriate processing is executed according to the material characteristics of the soft and hard materials, and a workpiece is processed well.</p> |
