1, cutting surface roughness: the cutting surface should reach a certain smoothness standard, the specific value depends on the application needs, such as Ra value (arithmetic mean deviation of surface roughness) needs to be in a certain range, such as Ra3.2 or smaller, depending on the material and use.

2, cutting verticality and slope: the cutting edge should be as perpendicular as possible to the surface of the material, the slope should be small, especially for the thickness of the larger plate, the verticality is more critical.

3, incision hanging slag size: the slag generated in the cutting process should be as little as possible, and easy to remove, hanging slag size should be within the allowable range, does not affect the subsequent treatment or use.

4, cutting edge rounded size: the edge should be smooth, the radius of the rounded corner should meet the design or process requirements, should not be too large or too small.

5, the amount of drag after the stripe: the stripe or texture formed during the cutting process should not be too deep or too long, so as not to affect the appearance or function.

6, cutting accuracy: the deviation between the actual cutting size and the design size should be within the allowable tolerance range to ensure high-precision machining.

7, flatness: the overall flatness of the cutting surface should meet the requirements to avoid deformation caused by heat generated during the cutting process.

8, the degree of cutting deformation: the deformation of the material after cutting should be controlled at a minimum, especially for thin plates or easily deformed materials.

In order to ensure that the cutting surface is qualified, it is usually necessary to use professional testing instruments for measurement, such as roughness meters, three-dimensional coordinate measuring meters, etc., to quantify the above indicators and compare them with standards or customer requirements. At the same time, the fine control of laser parameters (such as power, speed, focal length), auxiliary gas type and pressure, and material pretreatment during the cutting process is also the key to ensure the cutting quality.
