The aim of this study is to develop a new measuring technique bsed on laser diffraction such as Fraunhofer diffraction theory which is called the diffraction gauge method. This method makes it possible to evaluate a three-dimensional cutting-edge profile of a micro-endmill with precision of better than 100nm even though on-machine measurement. The measurement resolution was experimentally achived to be 15nm for a helical endmill and repeatability of ±50nm with valid accuracy for new tool. In this paper, in order to verify that the diffraction gauge method is of practical use such as on-machine measurement, the three-dimensional cutting edge profile measurements of a worn tool with the diameter of 0.3mm, which has performed side milling on graphite with 40000 rpm rotational speed, is discussed. The experimantal results show that the diffraction gauge method has enough high performance to be able to evaluate wear quantity of a worn micro endmill.

Language：Japanese Publishing type：Research paper (other academic)

SiC ceramics have broad application area due to its high temperarture strength, high heat conductivity and chemical stability. Recently, not only sintered but single crystal SiC are developed and it is expected the application for glass lens mold die material and semicondictor base plate. For the applications, it is required to develop important technology for obtaining defect free surfaces and reasonable cost for finishing. CMP process, as forming chemical reaction layer on material surface and remove, is considered to fulfill the requirements. In the report, polishing in high temperature is tried on SiC polishing to achieve the requirements.

A new optical measuring method of cutting edge profiles with a few nanometerresolutions for micro milling tool is proposed. The edge profile is scaled by the width between the first order maxima in a diffraction pattern, which relates to the spacing of a slit-type aperture formed between a reference knife-edge and a tool cutting-edge. The technique is applicable for on-machine measurement due to simplicity and long working distance of the optical system. In this paper, first, the theoretical analysis reveals the measurement resolution, and then the proposal of laser diffraction gauge method is mentioned. Next, the calibratability and the practicability of our technique are affirmed with fundamental experiments. Furthermore, experimental verifications are carried out for commercial tools such as straight-flute and helical-flute of micro endmills. Subsequently, excellent agreement of the profiles, which are measured with our developed experimental systems, with an image from scanning ion microscope verifies that the proposed method is efficient to accurately measure cutting-edge profiles.
