ABSTRACT
In this paper two technological manufacturing variants of a part are presented, one for fabrication on a vertical manufacturing centre with 3 axes YMC type and another one for fabrication on a horizontal manufacturing centre with 4 axes MCM type. The numerical control programs for the two manufacturing centers were made by using the CAD and CAM modules from the TopSolid software. The necessary times for doing the manufacturing were determined by their simulation, and by clocking the fabricating time of the products on the machines. After the analysis, there has been found for this case of study that, although there have been used the same cutting tools with the same cutting conditions, the higher number of fixings is not the most important factor for decreasing the productivity.
