Machine Tool Design and Static Behaviour Analisys Case of Study for a Drilling and Boring Machine

1. SOLID MODEL The main aim of the 3D design is to obtain a system that is very close to the real model considering the imposed functional conditions. In the machine tool design the parts are calculated for a proper strength and the stress level in each part is imposed to do not exceed material accepted values. A machine tool, particularly one that is used for drilling and boring processes (Figure 1), is made of many parts that generate an assembly. All parts are connected through screws, keys and pegs that have to be modelled. In the same time it is necessary that the level of contact stress to do not exceed the admitted value and is very important that from the phase of design to be known if parts of the machine lose the contact between them.
