The conveyors are used to transport various products in successive steps until they reach their destination and to ensure cargo volumes to balance the flow buffer. The conveyors monorail type are used for the transfer of the products, piece by piece and they can be suspended and can operate at heights and different tasks. In this paper is presented a method for the design of the drive shaft of a monorail conveyor, by using CAD-CAE applications.

Reverse engineering represents a method to retrieve information from an existing product, information which are then used for designing a new product or to reproduce it in order to make spare parts. In this paper is presented a case study on making a spare part of complex shape from a worn part. There are presented the stages of acquisition of data by scanning, the use of reverse engineering for the realization of the 3D model, the virtual manufacturing and then the machining of the workpiece CNC machine tools.

This paper presents how color Petri nets can be used in flexible manufacturing system models.. It is studied the cell from the Faculty of Engineering Management and Technology. In this cell process four parts: two pieces of revolution and two prismatic parts. In a first variant coloured Petri nets model is made without taking into account the time factor. This does not allow a prioritization of processing and the evaluation of manufacturing cycle time. If we consider the factor of time, coloured Petri nets model allows prioritization processing by the fact that each color is associated with a part it can be attach timing. May also be taken into account the processing times through timings associated with the transitions.
