- the carriage shape data is updated.
- the timing is not limited to before the production of the cutting plotter 1 and before shipment. For example, the timing may be executed every time the power switch is turned on, or may be executed during maintenance of the cutting plotter 1.
- the displacement sensor must be used as a device for measuring the bending.
- a laser side length measuring device, a straightness measuring device, or the like may be used.
- the present invention is characterized in that the cutting is performed by correcting the bending of the guide rail 31 and the Y bar 32 using the carriage shape measuring mechanism 100 and the carriage shape reading unit 51.
- the present invention can be applied to other types of cutting plotters or printer apparatuses such as a work medium drive type.
- the machining surface of the workpiece medium 2 is transverse (parallel to the XY plane).
- the present invention can also be applied to a cutting plotter of the type in which the end mill 43 is pressed from the lateral direction and is cut and processed by suction.
- Cutting plotter Work medium 20 Work table (medium support means) 31 Guide rail (first guide rail) 32 Y bar (second guide rail) 41 Slider (carriage) 43 End mill (processing tool) 50 Control unit (processing control means) 101 Displacement sensor (first direction deviation detection means, second direction deviation detection means) 103 X direction jig (second direction deviation detecting means) 104 Y direction jig (first direction deviation detecting means)
