The importance of CNC machining sequence
1. Before the important surface is machined, the fine datum should be rested to ensure the machining accuracy of the important surface.
2, After the fine datum is processed, then the rough surface, semi finish and finish machining of the main surface with high accuracy. The surface with high accuracy is also needed for finishing.
3, The surface as a fine datum should be machined at the beginning of the CNC process, because it is necessary to process other surfaces in subsequent processes.
4, When machining the base level, we need to use the rough datum. In single piece, small batch production and even batch production, the drawing process should be arranged before the machining process for the castings and forgings with larger size or larger size and larger size error, so as to provide a positive reference for the precision datum processing.
5, For the process of waste disposal,Finishing can be placed in the front, and some minor surfaces can be placed in the following process.
