In lathe operation, the most frequently used wrenches are chuck and tool holder wrenches, which different in structure function cannot be replaced, forgetting to remove will cause safety accidents. To solve above problems, this paper designs a new type of wrench, integrates functions wrench various screwdrivers, can easily change form by certain improves production efficiency eliminates hazards.

Cylindric and conic metallic parts are considered, which are subject to surface treatments (such as, e.g., lathe ®nishing or grinding) that make both Lambertian re ̄ection models and purely specular ones inadequate. A new re ̄ection model is introduced for such surface treatments, and a method is derived for the determination of the pose and the intrinsic geometric parameter of a cylindric surfac...

We regard a database as a computer model that enables us to simulate different modes of interaction with a real-world system. We describe new agent-oriented modelling principles that can be used to construct such models. These principles use systems of definitions ("definitive scripts") to record the current values of real-world observables, and represent a far-reaching generalisation of the pr...

A neural network based vision system for micro workpieces manufacturing is developing. The system has to recognize the shapes of the micro workpieces and to give the information for correction of the workpieces manufacturing process. The system prototype was proved off-line on the task of 3 mm screw shape recognition. The shape distortions were made with the incorrect position of the cutter in ...
