Excerpts

About CAD/CAM/CAE

By the late 1980s, automation and information technology at the shop-floor level had made manufacturing processes much simpler. With increasing competition, companies in the manufacturing industry were looking at ways to improve productivity, save time, reduce costs and increase customer satisfaction. The birth of 'Computer Aided - Design, Manufacturing, and Engineering (CAD/CAM/CAE) systems helped accelerate the automation in the manufacturing industry and revolutionized many difficult fields. The term 'CAD/CAM' refers to the application of computers in manufacturing - from the drawing stage to the production, to the machine, to the assembly shop, to the quality control department and to the finished parts store...

GM - Using CAD/CAM/CAE

In 1996, GM initiated a program to substantially reduce its VDP time from 42 months to 24 months. In the same year, GM entered into an agreement with Unigraphics Solutions to use its CAD/CAM/CAE software Unigraphics. In 1999, GM signed a three-year with the company as a follow up to the 1996 agreement. The agreement included the endorsement of Unigraphics' Internet-centric PDM application, iMAN . The new US $ 139 million software and services contract was believed to be the world's largest collaborative engineering network...

Reaping the Benefits

GM claimed to have saved hundreds of millions of dollars with the CAD/CAM/CAE systems. The new systems allowed the company to launch innovative new cars and trucks in the market faster. The company successfully reduced its VDP time to 24 months. GM aimed at reducing the VDP time to 18 months. The company reported a 13 % improvement in engineering productivity in 1997 and expected an additional 30% improvement by 2000. According to Jay Wetzel, the CAD/CAM/CAE tools enabled the company to save costs by reducing the number of physical validation builds. Cost savings were estimated at 30% during development and 10% during validation.
