Purpose: The main aim of research was to elaborate methods to estimate costs in construction series of types production process. Design/methodology/approach: Based on manufacturing cost of one element it is possible to determine cost of other elements belonged to the same construction series of types. The four main cost estimating methods were distinguished. The first method is feature-based. The technological operations are dedicated to specified pieces of element. Cost manufacturing of every piece is specified. Based on elementary costs the manufacturing cost of whole part is calculated. The second method uses construction similarity theory. The selected part manufacturing costs are functionally depended on main part manufacturing costs. The CAM method is based on time calculation from manufacturing process simulation. The simplified method uses normalized masses of analyzed parts pieces. The balance coefficients of those pieces are specified. Findings: Manufacturing cost estimation methods were analyzed. Those methods are based on construction and manufacturing technology. The main conclusion is that CAM method is most accurate. Research limitations/implications: The CAM method is limited to analyze only manufacturing process based on numerically controlled machines. The Feature-based method require developed database for analyzed part family. Practical implications: Presented method was applied in hydraulic props manufacturing cost analysis. Originality/value: Described analysis puts together and compares different cost estimating methods which allows choosing most suitable method for analyzed manufacturing process.
