The invention provides a cutting machine which may prolongs service life of a cutting knife in a simple structure and can reduce replacing work of the cutting knife. Cutting a sheet-like article is performed in an action position (5c) that becomes a part of a knife edge (5b) in a state of stabbing an oblique cutting knife (5) to the sheet-like article from above. A cutting knife elevation mechanism (6) is provided for elevating and moving the oblique cutting knife. Even if service life of the action position (5c) reaches the service life of the knife edge (5b), the action position can be switched to other action positions (5c) for continuous cutting. Since the knife edge (5b) is oblique, a distance between a reference position of a cutting head (2) and the action position (5c) varies according to the height of the action position (5c) relative to a knife tip (5a). Concerning the variation, control of the cutting head (2) is performed by modifying cutting data by the control portion (7), and thus cutting with no error can be performed.
