When entering as a radius cutter in your CAM-system, please use the RP value for programming. These conditons are for general guidance; in actual maching conditions adjust the parameters according to your actual machine and work-piece conditions. If the rpm available is lower than recommended please reduce the feed rate to the same ratio. Use only accurate and highly rigid machines. 11 Index 10 9 OIL 8 7 6 5 4 3 2 1
