The basis of a CAD (computer aided design) system is to provide 2-D or 3-Dimensional movement models to aid in production. The integration of CAM (computer aided manufacturing) with CAD has improved development and manufacturing standards over the last 50 years. But how did this integration of development with computer assistance become the definitive process of production?
Where Did CAD/CAM Begin?
The origins of CAD/CAM can be traced back to the sketchpad system innovated by Ivan Sutherland in 1962, with 3 separate branches of development periods that provided an expansion in basic operations.
The 3 Stages of Early CAD/CAM Development
- In the 1960’s, General Motors Research Laboratories attempted to eliminate hand drawn modeling and automate the drafting process in order to quickly change, correct or manipulate a model’s parameters.
- The aerospace and semiconductor industry began testing designs by simulation. This computer modeled testing of products increased manufacturing efficiency.
- By the late 60’s, designers had taken more direct control over the production process. Efforts to facilitate an efficient flow from design to the manufacturing process by using numerical control technologies had become widespread. This resulted in integration of design and manufacturing stages, contributing to increased production.
Although in its infancy, the early CAD/CAM system overcame development shortcomings by reducing expenses and increasing the speed of production by allowing designers and manufacturers to use the same system of encoded data. By decreasing the time from design to production, businesses could expand the scope of production and output increased.
The Game Changer
During the 1970’s silicon chips and microprocessors allowed for more powerful, yet more affordable computers. Smaller design firms could now access the technology, and were able to expand operations resulting in a boom of production and design applications.
Many of the functions of CAD/CAM today are simply improvements with modeling and incorporation of data analysis from conception and engineering to the manufacturing process. By updating the operating systems, the goal of CAD/CAM developers now is to refine the system to become faster and more user-friendly.
What Is the Future of CAD/CAM?
Future expectations of the CAD/CAM software is high, with designers seeking to push the boundaries of geometric shaping models, while continuing the trend of increased efficiency and pioneering advanced product designs.
