• Reduce the amount of material used to build one unit by incorporating several parts into one.
• Increase the value-added percent- age by eliminating all unnecessary parts handling and transportation.
• Reduce scrap.
• Make design changes (radius bends, hems, better accuracy) that can reduce the number of operations and increase the aesthetic value of the unit.
• Operate in an unmanned mode. • Reduce man hours/part.
• Improve product quality.
Electronic Design Automation: An HVAC Case History
In another case, an HVAC company using conventional production methods (turret presses and press brakes) was experiencing major bottlenecks and inefficiencies. The crux of its problem lay in an expansive product line consist- ing of 23 different models that could be customized from an assortment of more than 2000 product options. To com-
pensate for long lead times caused by an inefficient system, it countered by keep- ing a large number of parts in stock to act as a buffer. As a result, a lot of cash was tied up in inventory.
Salvation came via a plan to auto- mate all design work, so that as orders come in an office clerk receives a checklist of options from sales, registers the checklist in the computer (using Salvagnini EDA-OPS software) and assigns a delivery date. With all order data entered, the software kicks out engineering drawings, a bill of materi- als, machine files (CNC), routing slips and sheetmetal flat patterns (DXF).
In choosing an automated design tool in concert with a new punch- shear-bend line with material-storage towers, the company reduced design time from weeks to seconds.
