The design of a technological process supposes that the technologist should adopt some decisions in order to obtain the realization of the product in conditions of maximum productivity, at minimum costs and high quality. Taking into consideration all these criteria leads to the idea of creating an optimal technological process. The optimization of the conditions in which a cutting mechanical treatment process develops, needs the optimization of the factors determining the cutting process regime, that is the cutting depth (t), the lead (s), the cutting speed (v) etc. Also, in this case, the no optimization of the cutting regime is based on the objective functions represented by the minimum costs, maximum productivity etc., as well as a series of restrictions.
