くするという欠点があった。(Problem to be Solved by the Invention) However, when the above-mentioned processing material is an epoxy resin mixed with glass fiber, as shown in FIG.
A part of the glass fiber chips adheres to the cutting edge 2a of the cutting edge 2a due to work hardening, resulting in a so-called built-up edge.
This h1-formed cutting edge 3 has the drawbacks of making it difficult to perform cutting with the cutting tool, shortening the field of the cutting tool, and making the finished surface rough.

In the figures and FIG. 2, a cutting tool such as a cutting tool 2 is brought into contact with a molded product made of epoxy resin mixed with glass 1, which is rotating in the direction of arrow A, to cut the surface layer 1a of the molded product. . The above cutting tool was heated to 20 KH by vibration exciter 4.
Cutting is performed by ultrasonic vibration in Z to generate frictional heat that embrittles the surface layer 1a. In this case, in order to minimize the generation of frictional heat due to the cutting edge of the cutting tool on the surface layer, the cutting edge 2a of the cutting tool is constantly brought into contact with the surface 1b of the molded product and the molded product is ultrasonically vibrated in the longitudinal direction of the arrow 2.

形が望ましい。In the above explanation, the case has been described in which the cutting tool is vibrated ultrasonically in the longitudinal direction of the molded product, but the present invention is not limited to this, and the cutting tool can be vibrated in the circumferential direction or radial direction of the molded product. You can. In this case, it is desirable to have a vibration waveform that lengthens the time during which the cutting edge of the cutting tool makes point contact with the outer peripheral surface of the molded product.
また、切削工具を２０ＫＨ２で超音波振動させることは
必ずしも必要ではなく、可聴周波数の低周波数の低周波
で振動させてもよい。Furthermore, it is not always necessary to cause the cutting tool to vibrate ultrasonically at 20KH2, but it may be vibrated at a low frequency of a low audible frequency.

。[Effects of the Invention] As described above, in the cutting method of the present invention, a cutting tool is brought into contact with a rotating epoxy resin molded product to cut the surface layer of the molded product, and the vibration exciter of the cutting tool is used to cut the surface layer of the molded product. Since cutting is performed by vibrating and generating frictional heat that embrittles the surface layer, no built-up cutting edges such as glass 4I fibers are generated, making it easy to cut with cutting tools such as bits, and making cutting tools ideal. will not become short and the finished surface of the epoxy molded product will not become rough.
