Chapter 11 Ulrich and Eppinger - Product Design and Development
Manufacturing cost is a key determinant of the economic success of a product. Economic success depends on the profit earned on each item sold, and how many units of the product the firm can sell. if the price is set lower more sales can be achieved. But to maintain profit margin or profit on each item sold, cost also have to low. Design for manufacturing activity helps in lowering the cost of manufacturing by modifying the design to suit manufacturing capabilities without decreasing the quality of the product.
Design for Manufacturing
1. Estimate the Manufacturing Costs
2. Reduce the Cost of Components
3. Reduce the Cost of Assembly
4. Reduce the Costs of Supporting Production
5. Consider the Impact of DFM Decisions on other Factors
Details
1. Estimate the Manufacturing Costs
2. Reduce the Cost of Components
Understand the Process Constraints and Cost Drivers
Redesign Components to Eliminate Processing Steps
Choose the Appropriate Economic Scale for the Part Process
Standardize Components and Processes
Adhere to "Black Box" Component Procurement. Allow the supplier to design the product based functional specification.
3. Reduce the Cost of Assembly
Integrate Parts
Maximize Ease of Assembly
Consider Customer Assembly
4. Reduce the Costs of Supporting Production
Minimize Systemic Complexity
Error Proofing (Pokayoke)
