View factors of cylindrical spiral surfaces

A general formulation is developed for the radiation shape factors between a disk and a class of coaxial axisymmetric bodies such as cylinder, cone, ellipsoid, and paraboloid. In certain cases, the view factors can be derived analytically directly from the present technique, while in others, they can be generated from a single numerical integration. The analytical solutions for view factors from a disk to a coaxial cylinder based on the present approach are found to agree with those published earlier. The analytical formulae of view factors from disks or annular rings to circular cones, truncated cones, ellipsoid, paraboloids, and truncated praboloid are herein presented.

The wheel of abrasive belt is a special-shaped coated abrasive which has the advantage of good polishing quality, long life, and high efficiency, low cost and so on. Base on the features of the wheel of abrasive belt, through analyzing the basic motion relation of forming polishing spiral surface screw, the wheel of abrasive belt’s profile shape curve could be calculated by establishing the contact line equation of screw spiral surfaces with the wheel of abrasive belt rotating surfaces. Software to verify the correctness of the profile shape calculated, and in accordance with the wheel of abrasive belt profile shape curve to programming NC program. Start with the dressing experiments of the wheel of abrasive belt. Through analysis and research to get the wheel of abrasive belt’s profile shape curve meet the forming polishing standard.
