When designing a process, it mainly considers both precision and efficiency, and generally follows the principles of first face back hole, first reference after other, and first rough after finish. The machining center completes machining of all surfaces that can be machined in one setup. For the hole machining with higher requirements for position accuracy, special attention must be paid to the arrangement of the holes in the machining sequence. If improperly arranged, it is possible to bring back the backlash of the transmission pair and directly affect the position accuracy. For example, when arranging the hole machining sequence of the part shown in Fig. 5.6a, if the 5.6b line is processed, since the 5.6% hole and the 1.2.3.4 hole are oriented in the Y direction, the Y-direction backlash will cause The error increases, affecting the positional accuracy of the 5.6 hole and other holes. According to the route shown in Figure 5.6c, the introduction of backlash can be avoided. a) Part Drawing b) Processing Route 1 c) Processing route 2 Figure boring processing route During the machining process, in order to reduce the number of tool changes, the tool centering process can be used. That is, the same tool can be used to process the corresponding parts of the parts, and the second tool can be used for further processing. However, for the hole system with high accuracy, if the part is determined by the rotation of the table to determine the corresponding machining position, this method cannot be adopted due to the presence of repeated positioning errors.
