An algorithm for the synthesis of the optimal values of the parameters of precision manufacturing, assembly and balancing of assembly units and parts of machinery for agricultural purposes on the basis of the simulation of its dynamics. It is shown that the accuracy of the parameters of execution units of a conflict affect the cost of production and operation of the machine. This is the basis of the optimal values of these parameters for the search criteria to minimize the amount of these costs. Along with the optimized parameters into account other characteristics of the aggregates (their weight, mode of operation and so forth.), Which are related to the optimization of resources. A variation of the latter with the search for the optimal solution provides the required quality indicators of the unit. The proposed method of synthesis parameters tested calculation accuracy performance rotor grinding drum crusher feed DB-5. These calculations showed the possibility of redistribution of allowances for the execution of the test drum sizes for optimal reduction of production costs.
