CNC laser cutting design, as a precise and efficient manufacturing technology, plays an increasingly important role in modern industry. It can not only achieve complex graphic cutting, but also greatly improve production efficiency.
This article will explore the concepts, processes, precautions and wide range of applications of CNC laser cutting design in depth to help you better understand this technology.
What is CNC Laser Cutting?
CNC laser cutting is a process that uses a computer-controlled laser beam to cut materials. The high-energy-density laser beam is irradiated on the surface of the material to partially melt, vaporize or burn the material, thereby achieving the purpose of cutting.
What is CNC Laser Cutting Design?
CNC laser cutting design uses computer-aided design software to convert design drawings into digital instructions that can be recognized by laser cutting machines, thereby achieving precise cutting of materials. Compared with traditional cutting methods, CNC laser cutting has higher precision, faster speed and wider material adaptability.
Why is CNC Cutting Design so Important?
Improve efficiency: Through precise design, processing time can be reduced and production efficiency can be improved.
Ensure accuracy: Accurate design can ensure that the size and shape of the cut product meet the requirements.
Reduce costs: Optimized design can reduce material waste and reduce production costs.
Realize cutting of complex shapes: CNC laser cutting can achieve cutting of various complex shapes to meet personalized needs.
CNC Laser Cutting Design Process
Preparation of design drawings
Choose the right software: Choose the right software according to the complexity of the design and personal habits.
Draw detailed drawings: The drawings should contain all necessary information such as size, shape, hole position, etc.
Pay attention to details: Minor design errors may lead to processing failure.
File format conversion
Common formats: DXF, PLT, SVG, etc.
Choose the right format: Different laser cutting machines may support different formats.
Parameter setting
Cutting power: Choose the right cutting power according to the material thickness and type.
Cutting speed: Cutting speed that is too fast or too slow will affect the cutting quality.
Auxiliary gas: Auxiliary gas can improve cutting quality and reduce heat-affected zone.
Simulation cutting
Verify the design: Before actual cutting, simulate cutting through software to check whether the design is reasonable.
CNC Metal Design Considerations
Material selection: Different materials react differently to laser cutting, and appropriate cutting parameters need to be selected.
Thickness limit: The power of the laser cutting machine determines the maximum thickness of the material that can be cut.
Precision requirements: Select a suitable laser cutting machine and set parameters according to the product precision requirements.
Cutting path optimization: A reasonable cutting path can reduce auxiliary time and improve efficiency.
Heat-affected zone: Laser cutting will produce a heat-affected zone, and the impact on product performance needs to be considered.
Application Areas of CNC Laser Cutting Design
Industrial manufacturing: electronic products, auto parts, mechanical parts, etc.
Advertising industry: billboards, signboards, etc.
Art design: metal crafts, decorations, etc.
Architectural decoration: curtain walls, screens, etc.
Software for CNC Laser Design:
AutoCAD: As a classic CAD software, AutoCAD is widely used in the field of mechanical design. It is powerful, can create accurate two-dimensional and three-dimensional graphics, and supports multiple file formats for output.
CorelDRAW: CorelDRAW is famous for its excellent graphic design functions and is widely used in the fields of advertising design and packaging design. It has rich drawing tools and filter effects, which can create exquisite graphics.
Adobe Illustrator: Adobe Illustrator is a professional vector graphics design software, commonly used in logo design, illustrations, etc. It can create high-quality vector graphics and is suitable for laser cutting design.
Dedicated laser cutting software: In addition to general CAD software, there are also some software specifically for laser cutting design, such as LaserCut, CypCut, etc. These software usually have a more intuitive operation interface and richer laser cutting optimization functions.
CNC Laser Cutting Design Tips
Simplify the design: Simplify the design as much as possible and reduce unnecessary details to improve cutting efficiency.
Optimize the cutting path: Reasonable planning of the cutting path can reduce auxiliary time and reduce costs.
Consider material properties: The cutting parameters of different materials are different and need to be adjusted according to the material properties.
Leave enough gap: Leave enough gap between the cutting path and the edge to avoid adhesion during cutting.
Pay attention to node processing: For graphics with sharp corners or small rounded corners, node processing is required to avoid burrs during cutting.
