Computer aided mechanical design

In today?s business life where competition is getting warmer so, productivity, accurancy andfast working being more important, the engineering concept has to be more powerful. Theworld of technology is developing and it is hard to follow. The fastest developments are inthe field of ?Computer Aided Design? softwares. These softwares are making it able to befaster and accurate at all the periods of innovating a new product and manufacturingprocesses.In this work, you can find the inner structure, the usage in production, history, usage periods,methods, values of CAD and plus some types of most-used CAD softwares. Besides, thereare some opinions regarding the developments of CAD and PLM world. The theme dealedwith in this work is visual so there are as many figures as it is possible. Plus, there are somesuggestions regarding the Turkish meanings of some most-used terms which are in foreignlanguages because there are so many terms especially in English and some of them do nothave a meaning in our mother tongue.Keywords: Computer Aided Design (CAD), Computer Aided Manufacturing (CAM),Computer Aided Engineering (CAE), Product Lifecycle Management (PLM), Sketch,Feature, Object, Prototype, Tool, Kernel, Solid Model, Surface, Constraint.JURY:1.
