Title: Masayuki Iwai: Innovator in Machine Tool Technology
Introduction
Masayuki Iwai is a notable inventor based in Nagoya, Japan. He has made significant contributions to the field of machine tool technology, holding a total of 3 patents. His work focuses on enhancing the efficiency and reliability of machine tools, particularly in fault detection and thread cutting methods.
Latest Patents
One of Iwai's latest patents is a machine tool with fault detection. This innovative machine tool includes a spindle equipped with a cutting tool for processing workpieces. The control unit of the machine tool detects a value representing the torque applied on the spindle while it is stopped, with the cutting tool engaged with the workpiece. By comparing the detected torque value with a predetermined threshold, the control unit can determine if a fault has occurred. This method allows for accurate detection free from the effects of spindle acceleration or deceleration.
Another significant patent is related to a thread cutting machine and method. In this invention, axial loads encountered during thread cutting are minimized by controlling the interactions between rotation speed, axial feeding speed, feeding pitch, and feeding position. The invention generates a counterload by adjusting the feeding pitch to a corrected feeding pitch, which in turn alters the rotation speed while maintaining a constant feeding speed. This innovative approach enhances the efficiency of thread cutting operations.
