CNC machining skill you should know

First, The division of CNC machining processes can generally be carried out according to the following methods:
1. The tool-centric division method is to divide the process according to the tool used, and use the same tool to finish all the parts that can be completed on the part.
2. Partially-sequential processing method For parts with many processing contents, the processing part can be divided into several parts according to its structural characteristics, such as internal shape, shape, curved surface or plane.
3. The coarse and fine processing sequence method is used for the deformation-prone parts, because of the possible secondary deformation caused by rough machining, it needs to be calibrated. Therefore, in general, all rough and fine processing must be performed. separate.
Second , workpiece clamping method should pay attention to those aspects? In determining the positioning reference and clamping scheme, it should be noted:

1. Strive to unify design, process, and programming calculations. 

2. Minimize the number of fixtures, as much as possible after processing to complete all surfaces to be machined. 

3. Avoid employing manual adjustment programs.

Third, how to determine the knife point is more reasonable
1. The tool point can be set on the machined part, but note that the tool point must be the reference position or the machined part.
2. The origin position of the workpiece coordinate system is set by the operator himself. After the workpiece is clamped, it is determined by the tool, which reflects the distance and position relationship between the workpiece and the machine zero point.
Fourth, how to choose the route?

The rational choice of processing route is very important because it is closely related to the precision and surface quality of the parts. The following points are mainly considered in determining the cutting path: 

1. To ensure the accuracy of the parts required for machining. 

2. It is convenient for numerical calculation and reduces the programming workload. 

3. Seek the shortest processing route and reduce the empty knife time to improve processing efficiency. 

4. Minimize the number of program segments. 

5. To ensure the roughness of the workpiece contour surface after processing, the final contour should be arranged for the last pass.
