Title: Torao Takeshita: Innovator in CNC Technology
Introduction
Torao Takeshita is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of CNC (Computer Numerical Control) technology, holding a total of 6 patents. His innovative work focuses on enhancing the precision and efficiency of machining processes.
Latest Patents
One of Torao Takeshita's latest patents is a tapping apparatus and method. This CNC tapping machine features a spindle with an attached tap and a spindle motor for rotation. The load torque acting on the spindle motor is detected during tapping procedures without a workpiece and stored as referential torque data. During actual tapping, a detection device measures the load torque, allowing a computer to compute the difference between the detected load torque and the referential load torque. This process accurately detects the cutting load acting on the tap.
Another notable patent is a control method for NC machine tools. This method ensures high precision in contouring control, extends drill life, and reduces machining time. It involves generating an operation command signal based on the machining program and a time constant. The method also includes generating a velocity command signal and an electric current command signal, which are used to control the drive motor of the feed drive system. The machining mode is determined from the machining program, allowing for modifications to the command signals when the feed drive system is retracted.
