Quality Standards in Laser Cutting Process

The quality of a laser cutting machine mainly depends on its cutting quality, which is the most direct way to test the quality of laser cutting equipment. The cutting speed of laser cutting equipment is what customers should focus on. Then how to check the quality of laser cutting, and what should you pay attention to?

1. Perpendicular nature
   If the sheet metal thickness exceeds 10mm, the vertical degree from the cutting edge is very important. The laser beam deviates when it is away from focus, the cutting width is enlarged towards up or down according to the focus position. The cutting edge deviated a few millimeters from the vertical line. The more vertical the edges, the higher the cutting quality.

2. Deformation
   If cutting causes the part to heat up quickly, it deforms. This is especially important in fine processing as outlines and joints are usually only a few millimeters wide. In order to avoid deformation and reduce heat, it is necessary to control the laser power and use short laser pulses.

3. Roughness level
   The depth of the line at the time of laser cutting determines the roughness of the cutting surface. The lighter the line, the smoother the cut will be. In most cases, the roughness should be reduced as far as possible, so the lighter the line, the higher the cutting quality.

4. Depression and corrosion
   Depression and corrosion have an adverse effect on the surface of the cutting edge, affecting the appearance. They show up in truncation errors which should be avoided in general

5. Cutting width
   The notch width, in general, will not affect the cutting quality, except when a special precision line is formed in the part, the cutting width will be affected, because the cutting width determines the minimum inner diameter outlined. As the plate thickness increases, the cutting width will also increase. Therefore, to ensure the same high precision, no matter the width of the incision, the work area of the workpiece in the laser cutter must be constant.

6. Thermal Zone
   In laser cutting, the area near the incision is heated. Thus, causing parts of the metal structure to form such as some will harden. The thermal influence region refers to the depth of the region where the internal structure changes.

Those are some quality standards in the laser cutting process.
