Abstract
The steels with extra machinability are made according
to a special technological process. Such steels can be
machined at high cutting speeds. In addition, the
resistance of the tools used for machining, is higher
than in the case of ordinary steels. It depends on
several parameters, particularly on the steel chemical
composition, whether the steel will meet the criterion
of extra machinability. Special tests for each batch
separately show whether the steel has extra
machinability or not. In our research, the prediction
of machinability of steels, depending on input
parameters, was performed by genetic programming and
data on the batches of steel already made. The model
developed during the simulated evolution was tested
also with the testing data set. The results show that
the proposed concept can be successfully used in
practice.
