What are the principles of cnc machining/precision machining?
    Cnc processing and machining are very rigorous work, requiring high-quality operators, so what principles should be followed for cnc processing and machining?

    CNC parts processing needs to adjust the accuracy benchmark before surface processing to ensure the accuracy of surface processing. For the principle of datum coincidence, the design datum should be selected as the positioning datum to ensure the accuracy of product processing. Pay attention to this principle to avoid datum deviation caused by position error; the datum uniform principle, the uniform positioning datum surface of each surface treatment to ensure individual The position accuracy of the surface treatment room sometimes needs to follow the common reference principle and repeat the processing; the principle of self-reference. Some small machining allowances and a unified finishing process ensure the processing quality and productivity, and the precision-machined surface itself serves as a benchmark.

    After setting the benchmark and accuracy for cnc machining, rough machining is required for each surface with relatively high requirements, and then semi-finishing is best in the order of finishing. Surfaces with very high precision requirements also need to be smoothed; as a benchmark for accuracy Surface processing should be processed in the cnc processing process, because other processing surfaces in the subsequent processing procedures need to be positioned according to the datum, that is to say, the datum is required first and then the others; when processing the basic precision surface, rough datum positioning is required. In the processing and production of spare parts and small batches of parts and even in the production of batches and large-scale parts.

    In CNC lathe processing, the determination of the processing route generally follows the following principles.
①Simplify the workload of numerical calculation as much as possible, thereby simplifying the processing procedure and ensuring the accuracy and surface roughness of the processed workpiece. ②Control the length of the processing route to ensure that the shortest processing route is passed, the idle travel time is reduced, the processing efficiency is improved, and the tool loss is reduced. At the same time, the rigidity of the workpiece and the processing technology requirements should be ensured in the shortest cutting feed route. The feed route of finishing is basically carried out along the part contour sequence. Therefore, the focus of determining the feed route is to determine the feed route of rough machining and idle stroke. ③ For reusable programs, subroutines should be used.
