In last decade technology changes in CAD/CAM area so rapidly Autodesk, Dassault Systems, PTC etc. major company’s in this industry. All the products, we use or ride from cell phones, automobiles to planes and so much more, have been created using the advantages of CAD/CAM software.Right now people integrates Artificial Intelligence for CAD work .some companies developed online platforms for cad workby seeing all those CAD/CAM industry is go beyond Design, drafting and simulation. It is very amazing to see how the revolution happened in CAD sector.
During World War II, computing underwent a lot of development. Patrick Hanratty, “the father of CAD/CAM”, developed PRONTO (Program for Numerical Tooling Operations) the first CNC programming system, in 1957. At that time, mainframes were still large enough to take up entire rooms.During the 1960's CAD/CAM technology continued to evolve and spread to other areas. Automotive companies were the first to adopt the technology, and used it primarily to design automobile bodies. It then quickly spread to other sectors of industry, which were only too eager to abandon traditional pen and paper methods of drafting.
At present, CAD/CAM continues its steady path of progress. Much of this progress is in the form of refining past innovations to make them more efficient and user friendly. A ground-breaking CAD/CAM innovation has not occurred for a number of years, which seems to indicate that another sweeping change is just around the corner -- or maybe not. Thus, recent 3D innovations such as animated "walk-throughs" (a technique that allows designers to visually move in and around the rendered model, and see it from every possible angle) are still largely underused. The same is true of the bevy of collaboration tools currently available to the CAD/CAM user. The ability to combine CAD/CAM, with finite-element analysis and the accessibility of simulation and knowledge management, has yet to be fully embraced. Perhaps, it is in one of these areas that the next CAD/CAM breakthrough will occur. One thing that can be said with a degree of certainty is that research and development are currently ahead of user demand. When, and if, the garden-variety CAD/CAM user decides that they need to expand their range of capabilities, they will find a world of cutting-edge CAD/CAM tools at their disposal.
