<p>The invention relates to a method for determining the optimal lathe turning speed for machining a batch of pieces whose diameters have values comprised within a certain range, intended to be used for calculation purposes, with application in lathe turning cylindrical pieces. According to the invention, the method comprises a first stage of calculating the optimal rate of cutting vand optimal working cost C(v) for each diameter in a batch of pieces, in case of variable turning speed, followed by the calculation of a rate of cutting vand a working cost C(v) for each diameter in the same batch, at a selected turning speed n, in case of constant turning speed, the calculation of working loss Pper piece, in respect of the whole batch, as a consequence of using a single optimal turning speed equipment instead of a variable turning speed equipment, after which there is determined an optimal turning speed nto be equal to the value of the speed n for which the loss Phas the minimal value, finally there being determined the savings achieved when the entire batch is machined at the optimal turning speed, as compared with the case of machining at variable speed.</p> |
