1. Reasonable equipment selection. The majority of the machining allowance is usually removed during the rough machining of mechanical components, while it doesn't need high-precision machining of mechanical parts. As a result, the process should be finished with a machine tool of relatively high accuracy after rough machining with a tool of greater power and precision. The functionalities of the equipment may be fully utilized by roughing and finishing on various machines, and precision machine tools' service lives can be increased.
2. To improve the accuracy of the component processing, the processing of rough and fine mechanical parts should be done separately. Because of the significant quantity of cutting involved in the machining of rough mechanical components, the workpiece's surface clearly shows signs of work hardening due to cutting force, clamping force, heat, and precise parts. Greater internal tension is placed on the workpiece. If rough, machined mechanical components are also rough. Due to the rearrangement of stresses after continuation, the part's accuracy is soon lost. A low temperature annealing procedure or aging treatment should also be set up to remove internal tension after rough and final machining.
3. Please pay close attention to the necessity of arranging the heat treatment procedure while processing high-precision mechanical components. The following is how this position is set up: When machining mechanical components, metals that enhance cutting performance (such as annealing, normalizing, and tempering) are often arranged during heat treatment. Internal stress alleviation, such as aging therapy and adjustment treatment, such as general layout, are applied after rough machining but before completion. It is usually planned in the machining of mechanical components in order to enhance the mechanical qualities of parts, such as carburizing, quenching, and tempering. After heat treatment, the ultimate processing procedure should also be planned if the distortion is significant.
