In deep drilling, a series of our study is going ahead with the plan for improvement of accuracy. As the result, the control system for axial deviation of holes was developed. This paper deals with a new measuring method for axial deviation of holes, which was useful not only measurements of machined parts but also in-process sensing. The deviation can be evaluated from the path length and the pulse amplitude of the ultrasonic flaw detector in this new measuring system. In comparison with the optical measuring system using laser and coner cube prism, this tool can be simply constructed, because was not in need of a measuring pipe in tool shank and a prism holder in tool head. For this result, tool head of small diameter can be produced. In conclusion, the guide for practical use was presented on the control system for axial deviation of holes.
