Laser cutting machine cutting surface is not smooth may bring a series of consequences, affecting the final quality and performance of the product, including but not limited to the following:

1. Appearance quality decline: not smooth cutting surface will directly affect the beauty of the product, for applications requiring high surface finish, such as ornaments, precision parts, etc., this will be a significant problem.

2. The structural strength is affected: the uneven cutting edge may become a stress concentration point, reducing the overall structural strength and durability of the product, especially in the key parts of the load bearing or stress.

3. Follow-up processing difficulties: rough cutting surface in welding, assembly or other secondary processing, may require additional grinding, polishing steps, which not only increases the production cost, but also extends the production cycle.

4. Material performance damage: If the cutting process due to improper parameters lead to local overheating of the material, may change the microstructure of the material, affecting its physical and chemical properties, such as hardness, corrosion resistance, etc.

5. Dimensional accuracy decline: irregular cutting surface may cause dimensional deviation, which will affect the accuracy and efficiency of assembly for parts requiring high-precision coordination.

6. Increase the scrap rate: not smooth cutting surface may lead to some products can not meet the quality standards, thereby increasing the scrap rate, reducing the output of finished products, affecting the economic efficiency.

7. Reduced customer satisfaction: the final product does not meet customer quality expectations, which may lead to customer complaints and returns, damage the reputation of the enterprise, and may lose customer trust and market share in the long run.
