Abstract


In this paper, are presented numerical simulations results regarding the compensation of the errors. To realize that, the start point it given by the errors, which appear inevitably during the machining processes. This approach it was determinate a general and complex mathematical model for the most complex structure type 3T3R–3T3R. The model is able to calculate all generalized coordinates knowing only the initial linear and angular errors.  The initial errors can be imposed or measured; it must know the size of these. This thing allows that, the next parts that will correctly and precisely machine even those was improperly positioned into fixing devices.
