CAD/CAM Revolutionizes Engineering and Manufacturing Summary

  • Last updated on November 10, 2022

The popular use of computers to design buildings and mechanical parts can be dated to the groundbreaking release in 1982 of the software product AutoCAD. Computer-aided design (CAD) and computer-aided manufacturing (CAM) enhanced flexibility in engineering design, leading to higher-quality products and reduced time for manufacturing.

Significance

Prior to CAD/CAM, designers worked with the basics—pencils, erasers, and rulers. The power of computers to help operators more easily create, alter, and store three-dimensional designs has revolutionized the global marketplace. The software can allow a user to produce amazing walk-throughs, enabling a prospective client to examine a building from inside and outside. Operators can work more efficiently and can control a product from design to the end of the product’s life. The software can even design standard parts automatically. Products can be designed for one purpose and can easily be redesigned to fit new purposes. Thus, the user can keep an immense library of designs, manage manufacturing processes, and control material waste. Autodesk Computer-aided design and manufacturing[Computer aided design]

This long-range control allows companies to cut waste and consider the environmental impacts of their products. Companies can more easily redesign products to be unique to the countries in which the products are to be sold, which is a big advantage in the global marketplace. Computers decrease the time needed from design to production, and new software even simulates stress tests. When CAD/CAM added communication features, staff in all areas of the business became much better connected.

For companies producing products in mass quantities, CAD/CAM technology is invaluable. In particular, machines run by computer numerical control (CNC) have been vastly improved in accuracy by CAD. CAM sometimes is part of a CNC machine, so that the CAM program operates the machine, with a person managing its work, to achieve such tasks as drilling holes into metal at precise intervals. The merger with CNC and CAD made the machines faster, cheaper to use, and much easier to monitor.
