Milling machine having dynamometer for measuring cutting force

摘要

the invention the cutting force being applied to the object to be accurately measured in real time so that the structure can have improved milling relates to a machine. And milling machine according to the present invention, the frame, and rotatably coupled to the frame, in contact with the object to be processed and the spindle is coupled to a cutting tool for cutting the object to be processed, is formed in a toric shape between the frame and the spindle and the rail is arranged, the installation on the inside of the rail and the ball bearing unit and having a bearing in contact with the spindle, is coupled to be in contact with the bearing unit, the piezoelectric ceramic and to measure the vibrations transmitted through the bearing unit, the is coupled to contact the bearing unit, and a load cell for measuring the pressure which is passed through the bearing unit. ;
