Patent ID: 7346588

Claim:
A part cost estimation system which estimates a part cost including a manufacturing cost including a processing cost and a material cost, and a profit, comprising: a material information storage device configured to store information on the material to be used to manufacture a part, the material information including diameter measurements, roughness measurements, width tolerances, tolerances of the dimension of a cut portion and total length of the material; a processing cost information storage device configured to store processing cost information including information on each of processing facilities which can be used for performing a processing on a material to manufacture a part and information on a unit machining cost of each of the processing facilities; a shape designating device configured to designate a shape of the part; a processing designating device configured to designate a cutting or turning process to be performed on the material to form the part having the shape; a processing facility designating device configured to designate at least one processing facility among the processing facilities based on the contents of the processing; a processing time calculating device configured to calculate a processing time expended in processing the material based on the contents of the processing using the processing facility designated by the processing facility designating device to form the part having the shape, wherein said processing time further includes operating time expended in actually operating a processing facility to process the material and to set-up the processing facility; a processing cost calculating device configured to calculate a processing cost spent on manufacturing the part based on the unit machining cost and the processing time calculated by the processing time calculating device; and an adding device configured to add the processing cost for plural processings for manufacturing the part to determine a total processing cost of the part, wherein the processing cost calculating device is further configured to compare the calculated processing cost with a predetermined model processing cost, and wherein the model processing cost is a model manufacturing cost determined using the equation: model cost=ΣK mi *T i , where K mi manufacturing cost and T i is a processing time.
