Small laser engraving machine

1. Product introduction:

       Laser cutting of small laser engraving machines is an accurate method of cutting a given material using a CAD file. The parameters of the laser cutting process play an important role in the quality characteristics of the cutting edge. However, lasers have major barriers to their widespread use in conventional material processing, such as beam size limitations, high installation and replacement costs, and expensive fittings that require skilled workers. The researchers studied the effects of different laser parameters on trim quality, cut size, roughness and surface finish. Factors related to the study parameters of this process, such as laser power, spot size and size, and cutting speed versus the size of the resulting incision. We studied the effects of laser power and oxygen pressure on the change in slit width. The cutting quality of the small laser engraving machine is positively related to the cutting speed, power, pulse frequency and cutting speed. The machine can be inserted into five axes simultaneously. This machine is a complex form designed for cutting and its programming is much more complicated than in the case of 2D. Cutting can be performed in two-dimensional (two-dimensional), such as on a metal sheet, or in three-dimensional (three-dimensional) components that require cutting in width, length, and height. The most widely used industrial laser-cut sheet metal is gaseous carbon dioxide, solid Nd:YAG and the nearest fiber. Gas laser CO2 and solid state Nd:YAG lasers have the advantages of low beam power, high efficiency and good beam quality. Fiber has gained too much interest and development recently. In recent years, the application of pulsed yttrium aluminum garnet lasers has become more and more interesting for precision-cut sheet metal due to its high strength, low average beam power, good focusing characteristics, and narrow heat affected zone. Small laser engraving machines are usually better than ordinary laser Nd:YAG lasers Sivarao et al. The CO2 laser system has a fairly good beam with high output power quality enough to meet the requirements of thick section metal cutting.

The specifications of the laser cutting machine.

Experimental Materials:

       Acrylic acid is a plastic made from one or more acrylic acid derivatives. Polymethyl methacrylate, acrylic acid, or PMMA, due to its special weatherability, is a more widely used acrylic, strength, clarity and versatility. PMMA acrylic sheets have glass-like properties - clarity, gloss, transparency, translucency - in half the weight with up to 10 times the impact resistance. Because it is thermoplastic and softened at very high temperatures, acrylic can form almost any shape. Unbelievably durable, acrylic is a solution for a wide temperature range and has excellent weatherability compared to other plastics.

Experimental details:

       The Taguchi method is a technique for optimizing the process or design of a small laser engraving machine using multiple parameters. Researchers should always be fully aware of the various experimental methods in order to properly experiment and apply them to a single study to maximize efficiency and research results. The complete Taguchi method is actually composed of three main phases, all of which are intended to be offline. These three phases include system design, parametric design, and tolerance design. The parameter design phase of Taguchi is a stage commonly used in research. This stage requires known factors and production should be in progress. The main goal is to improve the performance of the production process by adjusting control factors. Three process parameters were studied: cutting speed (A), feed rate (B), and depth of cut (C). Based on the establishment of an L9 orthogonal array (OA) method, there are nine different experiments.
