Abstract


The traditional machine-tools setting’s consists to rend each characteristic independent, it is for example the case of the transfer of dimension starting to the reference surface which allows taking one adjustment parameter (corrector) by one dimension. The setting in this case is trivial, because there is no dependence between characteristics. The modern machines allow henceforth the simultaneous realization of several operations in one manufacturing phase that put in question the traditional setting. In this context, the relations between manufactured characteristics on the part (or probed points on surfaces) and the correctors are complex, because it exist dependence of setting between surfaces. The Total Inertial Steering (TIS) approach that we present in this article allows to establish a direct relationship between the tool offsets available on the machine and the points of the surfaces through an incidence matrix In most cases, this matrix is not square and therefore not invertible, because there are more probed points as correctors to adjust. The Gauss pseudo-inverse allows to find solution that minimize deviations on the next parts. The problem come up when the same cutting tool machine two surfaces with different point values, the resulting solution favors the one with the highest number of points, at the expense of the other surface which can remain not conform. To remedy this problem, we propose in this article an original method to rebalance setting on surfaces, and this regardless of the number of points.
