摘要：In the machine building industry it is met a wide variety of operations, and the most machines work after a regular cycle of processing, which generally takes place without the operator intervention, which favours the application of the workplaces poly-servicing system. In the first part of this article I made reference to the cycle of the processing on the machine tools, highlighting the analysis stages of the main aspects of the processing, as well as the determining procedure for the maintenance service cycle of the machine tools. Next I presented the main parameters used to characterize the poly-servicing and aspects of combining the processing operations under the poly-serving system, exemplifying the method of calculating of the optimal number of the machines that can be served by a single operator
