As an advanced processing technology, laser cutting has been widely used in many industries. The following is a detailed laser cutting process from design to finished product.
Design phase
1. Product demand analysis
Before laser cutting processing, we must first clarify the needs of the product. This includes factors such as the shape, size, accuracy requirements, material characteristics and the environment in which the product is used. For example, parts in the aerospace sector may require very high accuracy and material properties; For some decorative plate products, appearance and shape are key considerations.
2. Drawing and modeling
Drawing and modeling according to product requirements using professional computer Aided design (CAD) software. Designers draw accurate two-dimensional graphics or three-dimensional models to determine details such as cut contours and hole positions. This stage needs to ensure the accuracy of the design, because the subsequent laser cutting will be strictly operated in accordance with this design.
Preparatory phase
1. Material selection and preparation
Select the appropriate material according to the design requirements. Laser cutting can deal with a variety of materials, such as metal (stainless steel, carbon steel, aluminum, etc.), non-metal (wood, plastic, acrylic, etc.). The thickness and quality of the material also need to meet the processing requirements. When preparing the material, ensure that the surface of the material is smooth and free of oil and impurities, so as not to affect the cutting quality.

2. Laser cutting equipment debugging
Import the design file into the computer control system connected to the laser cutting equipment. Then, according to the type of material, thickness and other factors, the laser cutting equipment is adjusted. This includes setting parameters such as laser power, cutting speed, pulse frequency (for pulsed lasers), auxiliary gas type (such as oxygen for cutting carbon steel, nitrogen for cutting stainless steel, etc.), and pressure. Proper parameter setting is the key to ensure cutting quality.
Cutting stage
1. Positioning and clamping
The prepared material is placed on the laser cutting workbench and positioned and clamped by means of mechanical fixtures or vacuum adsorption to ensure that the material will not move during the cutting process. Accurate positioning is the basis of accurate cutting.
2. Laser cutting operation
The laser cutting device is started and the laser beam cuts the material according to the pre-set cutting path. The laser beam is focused on the surface of the material, so that the material instantly melts or vaporizes, and the auxiliary gas blows the melted or vaporized material away from the cutting area to form a incision. During the cutting process, the device will continue to cut according to the set cutting speed and laser power until the entire cutting task is completed.
Post-processing stage
1. Deburring and cleaning
After cutting is completed, some burrs or slag may remain on the edge of the cut. The cut is treated with sandpaper, a file, or a specialized deburring tool to remove burrs and clean up impurities such as slag to smooth the edge of the cut.
2. Quality inspection
Quality inspection of the finished product after cutting. This includes checking whether the dimensional accuracy meets the design requirements, using measuring tools (such as calipers, micrometers, etc.) for measurement; Check the quality of the incision, such as the perpendicularity and roughness of the incision; It is also necessary to check that the shape of the workpiece is consistent with the design. If quality problems are found, it may be necessary to adjust the cutting parameters and re-cut, or repair the workpiece.
Through the above laser cutting process from design to finished product, products can be efficiently and accurately manufactured to meet various needs. Laser cutting technology with its high precision, high quality cutting effect, in the manufacturing industry continues to play an important role.
