When using laser cutting to produce rapid sheet metal bended prototype parts from aluminum alloy raw materials, there are several key aspects that require high attention and careful consideration:

Laser Power and Cutting Speed:
Aluminum alloys have higher reflectivity and thermal conductivity compared to other metals, which can present challenges during laser cutting. The laser power and cutting speed need to be optimized to ensure clean, accurate cuts without causing excessive heat buildup or distortion in the material.

Focal Point Positioning:
Proper focal point positioning is crucial for achieving the desired cut quality. The focal point needs to be precisely aligned with the surface of the aluminum alloy sheet to minimize the risk of inconsistent or incomplete cuts.

Assist Gas Selection and Flow:
The choice and flow rate of the assist gas (typically compressed air or nitrogen) play a vital role in the laser cutting of aluminum alloys. The assist gas helps to remove molten material, prevent oxidation, and maintain a clean, narrow kerf.

Edge Quality and Burr Minimization:
Aluminum alloys can be prone to producing burrs and rough edges during laser cutting. Careful parameter adjustments, such as the use of pulsed laser modes, can help to improve the edge quality and minimize the formation of burrs.

Heat Accumulation and Distortion:
The high thermal conductivity of aluminum alloys can lead to increased heat buildup and potential distortion of the sheet metal during the laser cutting process. Strategies like optimizing the cutting sequence, employing active cooling, or using specialized clamping fixtures may be necessary to mitigate this issue.

Surface Contamination and Oxidation:
Aluminum alloys can be susceptible to surface contamination and oxidation, which can affect the quality of the laser cuts. Proper cleaning and handling of the raw material, as well as the use of protective gas environments, can help to maintain the integrity of the cut surfaces.
