Recently Brawo has acquired powerful software tools, which are used to simulate the manufacturing processes, such as forging, mechanical machining and dimensional inspection. Therefore our engineers are in a position to modify and correct errors during the simulation, by analyzing the effects of the planned processes and adjusting any causes of malfunctioning of the processes before production starts. All this sensibly reduces the manufacturing lead times of new items and allows our engineers to identify defects, especially for what concerns the forging stage, otherwise hardly noticeable on the physical pieces, but potentially dangerous in their final application. In particular, having to cope with increasing requests from our customers to manufacture forged pieces with complex shape and completely free of defects, the preliminary simulation has become an integrated part of our design process as far as forging dies are concerned. Once that the mathematic model of the forging tool has been produced and strictly before proceeding to its manufacturing, all the significant features which could influence the positive outcome of the forging operation are carefully analysed through the simulation. Features such as flow, speed and temperature of the material are measured at any stage of the deformation process. If necessary, issues can be addressed through modifications of the tools and of the scheduled parameters of the process. This gives us the advantage to be in a position, before tools have been already manufactured, to intervene on every feature without interferences or limitations. This, generally, enables Brawo to achieve an optimal result with costs and timing compatible with our customers’ expectations. As far as the mechanical machining are concerned, the simulation enables us, as in the case of the forging stage, to verify the consistency of every detail of this process and of the tools designed for this purpose.
By exactly following every aspect of the real process, such activity reveals beforehand and in practice any errors, particularly geometrical issues, that if not removed, might be the cause - in the production stage - of the impossibility to proceed (due to tools incompatibility) or worse, of dangerous collisions with the movable parts of the machines used for the production of the parts.
Furthermore, by comparing the virtual products of the simulation (item completely machined) with the mathematical model of reference, any inconsistency is immediately revealed and can then be corrected in that stage, so that all tools might reach the production departments, at the beginning of the sampling or production stage, within the lead times due and with the expected quality.
