  14. 14. 14 MACHINING COST ESTIMATION by Endika Gandarias MACHINING COST ESTIMATION
  15. 15. 15 MACHINING COST ESTIMATION • COST ESTIMATION consists in calculating the costs of the product or/and services that a company offers. • Most commonly used machining COST ESTIMATION methods are: • PRIMA (PRocess Information Maps) • Parametric calculation  an estimation of manufacturing cost • Analytic calculation  a more precise cost calculation method • WHY DO WE NEED TO DO A COST ESTIMATION METHOD? • To identify if a new product is feasible or not, and to modify it in an early design stage. • To define the product price. • To verify offers obtained from different suppliers  subcontracting • To identify the most economical process to manufacture the product. • To identify expenses and help in their minimization. • To take strategical decissions: eliminate a product, subcontracting, discounts,… by Endika Gandarias
  16. 16. 16by Endika Gandarias MACHINING COST ESTIMATION
  17. 17. 17 • As mentioned before, the price is defined by the market and not by our production/manufacuring cost. • So we must always produce below the market price. Direct cost + indirect cost + profit = product price  ideal business Direct cost + indirect cost = product price  no profit Direct cost + indirect cost < product price  no business • PROS: • It offers a very accurate estimation. • CONS: • It is a time consuming cost estimation method. • A lot of data is necessary to feed the method. MACHINING COST ESTIMATION ANALYTIC Cost Estimation by Endika Gandarias
  18. 18. 18 ANALYTIC Cost Estimation MACHINING COST ESTIMATION • In the ANALYTIC cost estimation, the final cost of the product is calculated by considering the real cost of all the steps/processes. • Each step/ process adds a value to the final product but for doing so a cost is necessary. • The main cost that are taken into consideration are as follows: DIRECT COST (DC) INDIRECT COST (IC) • Material cost • Tooling cost • Manufacturing cost • Any subcontracting cost • Commercial cost ( ~ %10 DC) • Indirect cost ( ~ %25 DC) DESIRED PROFIT ( ~ %15 (DC + IC)) PRODUCT TOTAL PRICE + + by Endika Gandarias Machining time calculus is required.
  19. 19. 19 MACHINING TIME by Endika Gandarias MACHINING TIME
  20. 20. 20 MACHINING TIME MACHINING TIME ESTIMATION METHODS by Endika Gandarias • The TOTAL MACHINING TIME (TT) calculus is very important to determine: • Manufacturing costs: Machine rate [€/h] * TT [h] • Machine work loads • Personnel needs. • Delivery time • The cutting time (TCUTTING) is the only one that can be accurately calculated. Rest of the times need to be estimated. • Most commonly used TIME ESTIMATION methods are: 1. By estimation. 2. By comparison. 3. By timing. 4. By the sum of elementary predefined times.
  21. 21. 21 MACHINING TIME • Time necessary to prepare the machine-tool to be ready to start machining: • Workholding device set-up • Toolholding device set-up • Material procurement • Tool procurement 𝑇 𝑆𝐸𝑇− 𝑈𝑃 : Set-up time 𝑇MANUAL OPERATION : Manual operation time • It is difficult to calculate properly because it varies depending on part’s dimensions and weight, machine tool, etc. • In general, manual operation time > cutting time. • Workpiece clamping and un-clamping • Non-cutting movements • Tool changes • Taking references • Measurements 𝑇CUTTING : Cutting time 𝑇UNFORESEEN : Unforeseen time • It is the time consumed in movements that remove material. • Non-cutting movements, such as fast approximations or retracts, are not considered. L: tool or workpiece displacement. V: displacement speed. • It covers all the time gone in unforeseeable events during the machining process (unexpected times). • Machine-tool breakdown. • Tool wear or breakage • Lack of raw material. • Blackout MACHINING TIME ESTIMATION METHODS by Endika Gandarias
  22. 22. 22 MACHINING TIME ESTIMATION METHODS MACHINING TIME • It consists in breaking down the operation in different smaller phases, so that a rough estimation can be made based on the experience of the technicians. • It is commonly used when: • unitary parts or small batches are required. • not enough data is available. • delivery time is short. • As it is a estimation method, it is not very accurate. BASED ON THE TECHNICIAN EXPERIENCE By estimation by Endika Gandarias
  23. 23. 23 • It consists in determining the time of a specific operation by comparing it with the time consumed a previously machined similar operation. • As it is a estimation method, it is not very accurate. However, it is more accurate than the estimation method. BASED ON OTHER PARTS EXPERIENCE MACHINING TIME MACHINING TIME ESTIMATION METHODS By comparison by Endika Gandarias
