80% of the cost of a product is built in at the design stage. Optimizing design for manufacture will reduce cost and improve quality.
The phrase Simultaneous Engineering was first used in the 1970s and is as relevant today as it was then. By involving manufacturing engineers, tool designers both in house and those of suppliers in the product design process, total development times can be radically shortened and product designs can be optimized from a manufacturing process point of view.
Designing components to reduce the number of operations to produce them. Eg. designing a casting so that all machining can be carried out from one side without turning a part around.
Designing components to optimize the ratio tooling cost / unit cost.
Standardization to take advantage of existing tooling and machinery.
Ensuring feedback from previous design quality errors are corrected in new designs.
Ensuring that demanded process tolerances are within machine capabilities
Optimizing product size and packaging to reduce space and optimize quantities that will fit on a palet.
Standardization of components to benefit from economies of scale and reduction of the number of SKUs held in inventory
Selection of lower cost alternatives.
Standardization of spare parts that will need to be held in inventory.
Design for maintenance
