High-precision gear machining based on on-machine 3D measurement

Recently, in gear machining, 5-axis machining centers (5X-machine) are gradually being used more often instead of dedicated gear cutting machines especially apparent in the large gear machining industry. From the point of view of improving transmission efficiency and reducing gear noise, there is a demand for high-precision gears. And there is a need for a simple measurement method that can confirm the overall shape, and a high-precision processing technology that uses the results. This paper describes our study of the on-machine profile measurement system using a 5X-machine, a laser scanning probe, and automatic corrective machining based on the measurement results.
