The precision of laser processing primarily depends on the following factors:
I. Machine Tool Performance
A machine tool is a working platform composed of a series of components. Elements such as motors, gears, and guide rails significantly impact processing accuracy. The overall precision of the machine tool encompasses both static and dynamic accuracy.
1. Static accuracy is primarily reflected in the precision of the gear rack, guide rails, and bed mounting surfaces.
2. Dynamic accuracy is primarily reflected in positioning accuracy and repeatability during cutting.
Generally, higher machine tool precision correlates with higher cutting accuracy.
II. Laser Beam Quality
The laser cutting process involves laser emission from the source, followed by focusing through the lens and laser head before striking the material surface. For laser processing, beam quality is a critical factor.
1. During precision machining of components, the stability of continuous laser emission directly impacts cutting accuracy. Greater stability yields higher overall component precision.
2. A smaller spot size formed by the beam after passing through the focusing lens indicates higher precision. Variations in focal position also significantly affect accuracy.
III. Control Card and Process Parameters
The laser control card serves as the brain of the laser cutting machine, governing both the process parameters (cutting speed, power, gas pressure, etc.) and the motion trajectory during cutting. The selection of process parameters directly impacts cutting precision, while the planning of the motion trajectory also influences precision to varying degrees.
Generally, a superior control system offers greater compatibility and stability, incorporates richer built-in algorithms and combinations, and employs more rational processing paths. Consequently, processing precision is naturally enhanced.
IV. Material Quality
Different materials exhibit varying laser absorption rates and thermal deformation levels, leading to differing precision outcomes after laser processing. For instance, when processing stainless steel versus aluminum on the same laser machine, stainless steel yields superior results due to aluminum's higher reflectivity compared to stainless steel.
