What factors can affect the cutting quality of sheet metal parts?

The following are some factors that can affect the cutting quality of sheet metal parts:

I. In terms of cutting equipment:

Equipment precision: The precision of cutting equipment directly determines the dimensional precision of sheet metal parts. If the positioning precision of the equipment is not high and the motion control system is unstable, it will lead to a large deviation in cutting size.
Laser power: For laser cutting equipment, the power of the laser beam affects the cutting ability and speed. Too low power may not be able to completely cut thicker plates, or there may be defects such as slag and burrs on the cutting edge; too high power may lead to excessive cutting and deteriorate the edge quality.
Cutting head quality: The focusing performance, stability, and durability of the cutting head are crucial to cutting quality. A high-quality cutting head can ensure accurate focusing of the laser beam and obtain a finer cutting edge.

II. In terms of sheet material:

Material type: Different metal materials have different physical and chemical properties and different adaptabilities to cutting. For example, some materials with high reflectivity (such as copper, aluminum, etc.) may require special cutting processes to avoid reflecting the laser beam and affecting cutting quality.
Plate thickness: Thicker plates usually require higher power and longer cutting time, and problems such as incomplete cutting and edge inclination are prone to occur.
Material surface quality: If there are impurities such as oil stains, rust, and oxide layers on the surface of the plate, it will affect the absorption and penetration of the laser beam and lead to a decline in cutting quality.

III. In terms of cutting process parameters:

Cutting speed: Too fast cutting speed may lead to incomplete cutting and many edge burrs; too slow speed will increase the heat-affected zone and cause the edge to change color and deform, affecting cutting quality.
Auxiliary gas pressure: The pressure of auxiliary gases (such as oxygen, nitrogen, etc.) will affect the cutting effect. Appropriate gas pressure can blow away slag and keep the cutting edge clean, but too high or too low pressure may lead to cutting quality problems.
Focus position: The focus position of the laser beam has a great influence on cutting quality. Too high or too low focus will reduce the cutting ability and deteriorate the edge quality.

IV. In terms of operators:

Technical level: The familiarity, operation skills, and experience of operators with cutting equipment will affect cutting quality. For example, correctly setting cutting parameters, adjusting equipment, and handling abnormal situations during cutting all require a certain technical level.
Sense of responsibility: The sense of responsibility of operators is also very important. Carefully checking the quality of the plate and the equipment status and strictly following the operating procedures can effectively improve cutting quality.
