We know that the scope of laser cutting machines is very wide, not only in aerospace, automotive processing, mechanical processing and clothing industries, but also in the field of plexiglass processing. So what are the advantages of the laser cutting machine when processing plexiglass? When the laser cutting machine is processing plexiglass, select different processing parameters such as laser power, spot scanning speed, etc. The stress-induced fracture depth can reach 100 Micrometers to several millimeters means that glass with a depth of 100 micrometers to several millimeters can be cut in one step using the laser method. Because this process relies on thermal mechanical stress, the fracture depth and cutting speed are closely related to the expansion coefficient of the material itself. Generally speaking, the minimum expansion coefficient of glass suitable for laser cutting should be 3.2x10-6K-1. Fortunately, most ordinary glasses meet this requirement. Compared with the traditional mechanical cutting method, this new method has several important advantages. First of all, this is a dry process that can be completed in one step. The edges are smooth and tidy, and no subsequent cleaning and sanding are required. In addition, the separation process induced by the laser machine produces a high-strength, naturally tempered edge without tiny cracks. Using this method avoids unpredictable cracks and breakages, reduces the rate of defective products, and increases output. Edge quality '' qualitatively describes the dynamic difference between three different cuts on a 1.5 mm thick glass sheet. The cutting edge of the glass is clean without splinters and cracks, and no subsequent processing steps are required. Because the laser is a non-contact tool, there is no tool wear problem, which can ensure continuous and uniform cutting thickness and edge quality. As a comparison, 3(b) shows the edge of cutting with a metal wheel, and it can be seen that there are various residual tension components along the cutting line. 3(c) is the result of diamond grinding wheel cutting. Many tiny cracks can be seen. For many applications, the cutting edge needs to be polished. In order to quantitatively evaluate the edge quality, according to ISO3274, the Stylus profile measuring instrument should be used to measure the edge of the laser cutting machine. Authoritative measurement shows that the average roughness (Ra) is less than 0.5 microns.
