What is design for manufacture (DFM)?
Design for manufacture (DFM) is a methodology that simultaneously considers all of the design goals and constraints for products that will be manufactured. The illustration shows how product design, material, labor, and overhead influence product cost.
It is clear that much of the overall product cost is determined during the product design phase when the design goals and constraints should be considered.
Design for manufacture methods can increase profits by improving sales and decreasing costs. Production costs can be cut by designing less expensive parts that can be assembled at lower total cost. Products designed in group technology families with common parts can be built with lower inventory, in less production space, and fewer machines. Products designed for flexible manufacturing can quickly respond to changing market conditions while eliminating finished goods inventory. Quality and reliability can be assured by design and process controls rather than expensive testing, diagnostics, and rework.
With design for manufacture (DFM) methods in place, development costs will be lower with maximum use of reusable engineering, modular design, and catalog parts. Products will reach the market sooner because they are designed right the first time. The result is a timely, quality product that will satisfy customer needs at a competitive price.
