The cutting quality of a metal laser is important as it impacts downstream processes. However, judging said cutting quality is fairly straightforward if you know what to look for. In this article we’re going to take a look at what aspects you should be paying attention to when judging the cutting quality of a metal laser cutter. Let’s get to it.
The Ultimate Guide to Assessing Cutting Quality in Metal Laser Cutters
How to judge a metal laser’s cutting quality: 5 aspects
The quality of a cut by a metal laser cutter can be assessed according to the following aspects:
Cutting width
In order to ensure high levels of accuracy, the width of the cut should be consistent and match the desired dimensions. Regardless of the width of the incision, the working area of the workpiece in the laser cutter should be consistent.
Deformation
If the laser causes the part to heat up sharply during cutting, it will likely deform. The importance of this becomes apparent in fine machining since connections are only a few millimeters wide.
Heat affected zone
The width and depth of the heat affected zone (or HAZ) should be minimal – indicating that cutting does not overheat the metal.
Edge quality
Roughness affects both the appearance of edges as well as the friction characteristics. The higher the roughness, the lower the cut quality, and vice versa.
Cut texture
When a slab is cut at high speed, the molten metal will be ejected along the path of the laser beam, as opposed to appearing in the slit below the laser beam. As a result, the curved textures are formed at the cutting edges, closely following the moving laser beam.
