The Researches on how to estimate cost during design stage are important because the cost is becoming the key factor between time, cost and quality which determine the competitive performance of products. On the basis of analysis of the related literature at home and abroad, the following contents are studied.The cost construct and its contributing factor in the mechanical product life-cycle are analyzed and the generation rules of product manufacturing cost are studied.The relations between design feature, machining feature and cost feature are studied. Cost estimating model based on feature mapping and its application method are presented in concurrent engineering.On the basis of the analyses of the generation rules of product manufacturing cost, data model of cost feature of products, its structure and application are presented on theory about feature mapping and object-oriented method, which lead to the concurrence of product design and product cost estimating.The importance of cost estimating and the analyzing methods of cost construct and cost difference are studied. The methods give the necessary cost information to designer in time which helps to modify design and reduce cost.On the basis of researches above, the database of cost estimating function of mechanical product are constructed. The software system of cost estimating and analysis of mechanical product is developed. The effectiveness of cost estimating method is validated by piston shaft of oil damper.
