Components and parts cost estimating method and system, cost standard information offering method and system

Abstract

An external storage device of a component cost estimation system stores various cost information representing a component material and its cost in association with each other, and a component manufacturing step and a cost involved in the step in association with each other. An information processing apparatus specifies a material of a component to be manufactured, and a plurality of manufacturing steps. Then, the information processing apparatus retrieves a cost of the specified material, and costs corresponding to the specified manufacturing steps from the cost information, and estimates a cost of the component based on the retrieved costs. The cost of the component is computed by adding up the cost of the material and the costs involved in all the manufacturing steps.

Description

technical field

[0001] The invention relates to a component cost estimation method and system, and a cost standard information providing method and system. Background technique

[0002] Conventionally, in the manufacture of industrial products, technicians with specialized knowledge such as parts processing estimated the manufacturing costs of parts and metal molds for making parts.

[0003] In recent years, in order to estimate costs, systems using computers have been introduced, and even people who are not familiar with parts processing, etc. can estimate costs.

[0004] For example, the cost estimation method disclosed in Japanese Patent Laid-Open No. 7-282142 is an automated method from extracting processing elements to calculating estimated costs. Identify the shape of the sheet metal product based on the cross-sectional shape data of the sheet metal product, select the processing technology of the sheet metal product based on the identified cross...
