Abstract:
A cutting apparatus comprising:a holder device including an X-axial transfer table, and a chuck table rotatably mounted on said X-axial transfer table for holding a workpiece at a workpiece cutting position of said X-axial transfer table; a cutting device including a rotary blade for cutting the workpiece when the workpiece is held by said chuck table at said workpiece cutting position; and a marking member fixed to said X-axial transfer table; wherein said X-axial transfer table and said cutting device are arranged to be movable relative to each other such that said X-axial transfer table can be driven to move in an X-axial direction relative to said cutting device, such that said cutting device can be driven to move in a Y-axial direction, perpendicular to said X-axial direction, relative to said X-axial transfer table and such that said cutting device can be driven to move in a Z-axial direction, perpendicular to said X-axial direction and said Y-axial direction, relative to said X-axial transfer table; wherein said marking member is fixed to said X-axial transfer table in such a position that said rotary blade of said cutting device can make an alignment mark on said marking member in a location spaced apart in said Y-axial direction from the workpiece when the workpiece is held by said chuck table at said workpiece cutting position, so that said rotary blade of said cutting device can make the alignment mark on said marking member while the workpiece is held by said chuck table at said workpiece cutting position.
