Laser cutting machine cutting quality judgment

Generally speaking, laser cutting machine will check the quality of cutting, but laser cutting machine cutting quality inspection standards, cutting effect is still difficult to unify. Cutting effect can be mainly judged from the following aspects:

1. The roughness

Cutting edges more or less leave cutting lines, and the depth of the lines determines the roughness of the cutting surface. The lighter the texture, the lower the roughness, the smoother the surface. Generally speaking, the thinner the material thickness, the lower the cutting surface roughness; The surface roughness cut with nitrogen or argon is lower than that cut with oxygen.

2. The vertical degree

Due to the focusing and divergent characteristics of the cutting beam, during the cutting process (especially when cutting thick plates), the size of the light spots with different depths in the material thickness direction is not consistent, so that the cutting surface and the plate surface cannot reach 90 degrees, or the upper surface is wider or the lower surface is wider. Generally speaking, the thinner the material, the better the perpendicularity. The better the quality of the beam, the better the perpendicularity. In addition, it also relates to the relative position of the focal point of the spot and the direction of the thickness of the material in a particular processing process.

3. The burr

Cutting edges should be free of burrs and burrs need follow-up treatment. This is related to the matching of process parameters, material type and beam quality in a particular machining process

4. The deformation

Because the nature of laser cutting is thermal cutting, the plate will inevitably deform. Good cutting should minimize the negative effects caused by this. Special care should be taken when cutting the board. In general, the faster the cutting speed, the narrower the cutting seam, the larger the gas flow, the smaller the deformation.
