Title: Innovations of Yuji Mizukami
Introduction
Yuji Mizukami is a notable inventor based in Tokyo, Japan. He has made significant contributions to the field of threading control systems and numerical control apparatuses. With a total of 4 patents, his work has advanced the technology used in various manufacturing processes.
Latest Patents
One of his latest patents is a "Thread control method and system therefor." This invention focuses on a threading control system that performs threading operations by synchronizing the movement of either a cutter or a workpiece with the rotation of the main spindle. This innovation ensures that the ridge is not damaged and maintains the dimensional accuracy of the thread, even when the main spindle speed varies. The system includes a threading computing section and a main-spindle angle computing section that adjusts the threading start timing based on the servo-spindle acceleration time-constant of the feeding spindle.
Another significant patent is the "Numerical control apparatus and numerical control system." This invention involves an NC apparatus that controls the position of a tool by driving multiple shafts with servomotors. It features at least one clamp shaft that can be mechanically clamped or unclamped. A clamp determining unit assesses the state of the clamp shaft and outputs a signal accordingly. A correcting unit then adjusts the position instruction value or detection value of other shafts to eliminate any positional errors caused by the movement of the tool.
