Feature Recognition techsheet

The change in the market forces machining companies to update product design, complexity, quality, durability and delivery times. This is made possible by the development of computer technology. During the development of a 3D model in CAD (Computer Aided Design), data can be adjusted quickly. On the basis of Model Based Definition (see techsheet model based definition) all relevant data concerning the product can be placed inside the 3D CAD model. By using feature recognition the CAM system can execute machining strategies automatically (Stănăşel, Blaga, & Buidoş, 2019).
Once the 3D CAD model is loaded in the CAM program, the feature recognition tool can automatically recognize types of operations such as holes, slots and pockets (Sheen & You, 2006). Because these processing rules have already been defined, a quick identification is possible, after which the functions are automatically specified (Stănăşel et al., 2019). The users of the CAM program can change the editing knowledge at any time.
When sufficient information has been added to the program, a fully automatic production process can be achieved. However, the technology is currently limited to 2,5D prismatic features. At the moment, relatively simple features, such as holes, can be automatically generated with feature recognition. This reduces the overall programming time and leaves more time for the programmers to work on challenging features.
