OPTIMAL FIBER PATH GENERATION METHOD FOR COMPOSITE PART MANUFACTURING

A novel method designs and analyzes composite parts including optimal manufacturing strategies. The invention analyzes part design including curvatures and other surface topology to formulate an optimal strategy for material layup, number of plies, initial orientation angle, and towpath steering vectors. The method computes an optimum starting point for each fiber path and a stagger offset for each successive fiber path to as to eliminate or minimize gaps and overlaps between adjacent plies. Intermediate surfaces are generated by a polynomial discretization method which generates large computational time savings and enhances blending of adjacent zones to control surface smoothness. The method further calculates a variable steering path for the layer taking into account material parameters and limitations such that plies originating in the same location have a variable orientation angle and follow any reference curve generated by the method to maximize strength and minimize weight of the component.

Power consumption output device and system for an automatic lathe

A power consumption output device for an apparatus that manufactures a plurality of products from a quantity of supplied material in a series of repeated cycles, includes a detector for detecting power consumption in a time period that includes at least the time needed for manufacturing all of the products that can be manufactured from a given quantity of supplied material, from the time at which the supply of the material to the apparatus commences to the time at which any remaining material is ejected, and delivers an output indicating power consumption per product by using the power consumption detected by the power detector and the number of products manufactured from the given quantity of supplied material. The device is thus capable of precisely calculating the electricity cost per product manufactured by an apparatus whose power consumption varies from one cycle of operation to another.
