<p>To increase the output of a fluid pressure machine and to obtain an economical operating cycle, the totality or a fraction of the travel of the machine tool-holder is measured completely or partially and is compared with the totality or fractions of an order travel. The differential value or values obtained are used, after analysis, in the form of control signals, for the control of the following travel of fraction or travel which is measured again. It is then compared with the overall or fraction of length of another order travel obtained by the differential value or values. The differential values obtained by this new comparison are used, after analysis, for controlling of the following travel, etc. </p> |
