Sheet cutting is a commonly used processing technique. We need to understand both the cutting of the material and the cutting methods to fully comprehend sheet cutting. So today, let's delve into some knowledge on this topic. When cutting, some parts may deform, so measures must be taken to control and prevent this. How should we proceed? Below, the editor will provide a detailed analysis and explanation. Effective measures to control deformation of cutting pieces generally include:
The purity of the oxygen used must be sufficient, as it affects the smoothness of the cut surface. Insufficient oxygen purity can lead to a rough cut, thereby impacting the quality of the cutting.
After multiple workpieces are cut, do not rush to clean them, as this can effectively control deformation.
3. For thin steel plates, local cooling can be applied, and cold shrinkage values can be pre-set in the programming to compensate based on the length, width, and thickness of the cutting area.
4. The perpendicularity error between the cutting nozzle and the steel plate surface should be nearly zero, meaning the cutting nozzle should be perpendicular to the steel plate surface. Otherwise, dimensional errors will appear in the cutting section.
5. Delicate or easily deformed workpieces should be placed in the center of the solid board, with sufficient distance between each piece.
6. Choose a reasonable cutting sequence and properly select the position of the piercing points to prevent deformation of the cut parts.
That wraps up today's tip on how to prevent workpiece deformation during cutting. Did you catch that?
