Abstract:
This research is directed toward increasing level of automation of a manufacturing execution system (MES). In the concept presented central role belongs to the machining feature and the STEP standard that defines it. Particular feature type advices specific machining algorithm on its one. This intrinsic property of machining feature was already recognized by STEP-NC developers. But if we combine or extend feature's STEP model with Product and Manufacturing Information (PMI) than it can become driver for not only CNC machinery but other manufacturing resources too, like robots, transport subsystems, embedded systems, etc. Datum features, GD&T and special annotation can complement feature definition to advise positioning, robot gripping, fixture setup and other algorithms. With the aim to obtain common solution, independent of a particular CAD system, the only STEP format of test parts were used. The initial solutions were developed using Visual C++ 2013 and open C++ class libraries: ST-Developer from STEP Tools, Inc. and OCCT from Open Cascade
