Device and method for processing artificial tooth

A method for processing an artificial tooth using an artificial tooth processing device including a spindle base that is driven in up-down and left-right directions;

• a spindle that is mounted on the spindle base and rotated by a motor;
• a processing tool that is mounted on an axis end of the spindle and rotated together with the spindle;
• a workpiece holder that fixes a workpiece;
• a workpiece mounting portion on which the workpiece holder is mounted, and which is rotationally driven about an axis of the workpiece holder and driven in a back-forth direction;
• and a control portion that controls driving of the spindle base in the up-down and left-right directions, driving of the workpiece mounting portion in rotation and in the back-forth direction, and driving of the spindle and the processing tool in rotation, the method comprising:
• setting of a first reference position of the workpiece when the workpiece mounting portion on which the workpiece and the workpiece holder are mounted is at a first rotational position;
• forming of a first artificial tooth by processing one end of the workpiece based on the first reference position;
• rotating of the workpiece mounting portion and the workpiece holder to a second rotational position by a predetermined angle (r) and setting a second reference position of the workpiece;
• and
• forming of a second artificial tooth by processing the other end of the workpiece based on the second reference position.
