A best-fitting algorithm for optimal location of large-scale blanks with free-form surfaces

This paper is mainly concerned with an algorithm for the optimal location of large-scale blanks with free-form surfaces. By means of rotation, transitional motion of a free-form surface and a projection method, the pre-location and adjustment and final spatial posture control are realized to assure that the blanks coincide with the theoretical surfaces. Therefore, the distribution of the stock allowance is optimized. The amount of negative stock and the material to be removed are reduced. The result shows that the algorithm is effective.
