2. Deformation caused by workpiece clamping

When clamping the workpiece, you need to select the correct clamping point and select the appropriate clamping force at that position. Therefore, it is necessary to keep the clamping point and the supporting point in line, so that the clamping force acts on the support, the clamping point should be as close as possible to the working surface, and the position where the force is not easily caused by the clamping deformation is selected.

3. Deformation caused by workpiece processing

During the cutting process, due to the cutting force, the workpiece will have an elastic deformation toward the direction of the force, which is the knife phenomenon. For similar deformations, corresponding measures can be taken on the tool. When finishing, the tool is required to be sharp, so that on the one hand, the resistance formed by the friction between the tool and the workpiece can be reduced. On the other hand, the heat dissipation can be improved when the tool is cut. Ability to reduce residual internal stress on the workpiece.

The above are some of the more critical points. In order to ensure the quality of CNC machining parts, it is necessary to pay attention to these points in order to process CNC machining parts.
