With a total of four patents to his name, Terada has been instrumental in developing advanced methods and systems for workpiece machining that enhance precision and efficiency in manufacturing processes.

Latest Patents

Among his latest patents is a groundbreaking **Workpiece Machining Method**. This invention describes a sophisticated machine tool that consists of various components, including a spindle to retain a tool, a spindle motor, and a feed device that facilitates the relative movement between the workpiece and the tool. A significant feature of this patent is the ability of the spindle motor control unit to continuously vary the rotational speed of the spindle, both periodically and non-periodically, with a specific amplitude in relation to a target speed. Similarly, the feed motor control unit synchronizes the movement speed between the tool and the workpiece, ensuring that the ratio of spindle rotational speed to moving speed does not remain constant during critical periods of machining.

Another innovative patent is the **Controller for Spindle Motor**. This controller is designed to generate a varying speed command signal, which fluctuates with predetermined amplitude and period. It features a current control unit that creates a current command signal based on this varying speed. Additionally, a feedback control unit and a learning control unit work in tandem to fine-tune the performance by adjusting for any cutting resistance disturbances, thereby ensuring a more responsive and accurate machining process.
