In the first section of the final qualification work of the master, the choice of a CNC machine according to a modified methodology for evaluating productivity is demonstrated. In the second section of the final qualification work of the master, the analysis of the manufacturability of the workpiece âGridâ is presented, the parameters of the output volume are determined, the technological process for manufacturing the part using CNC machines is developed, the selection of equipment and accessories, the analysis of allowances and inlets from the point of view of the conditions of their need and sufficiency when using CNC machines, calculation of cutting modes and rationing of operations. The third section of the final qualification work of the master presents the procedure for calculating cutting forces and power. The order of designing a special machine tool for installing parts is shown. The calculation of the error of this device is shown. |
