Subject: bevel скоса кромки??? или конус ???If a cone is designed with multiple bevels (figure 3.3), this shape will provide a slipping and scraping action. The normal center of rotation for each cone bevel is at its projected apex. Since the projected apices of the separate cone bevels do not fall at the same point along the cone centerline and do not fall on the bit centerline, true rolling cannot occur and the cone must slip and scrape against the surface beneath. |
