I. Definition
Five-axis machining is the most accurate processing method, the three linear axes and two rotating axes move at the same time and can be adjusted in different direction, to ensure the continuity and efficiency of processing, five-axis linkage can reduce processing errors, and polish the interface to be smooth and flat. Five-axis machining is widely used in aerospace, military, scientific research, precision instruments, high-precision medical equipment industry and other fields.
II.The advantages of five-axis machining
1. Complex geometric shapes and surface processing ability is strong, because the five-axis machine has multiple rotation axes, it can be cut in different directions. Therefore, compared with traditional three-axis machining, five-axis machining can realize more complex geometric shapes and surface machining, and can improve production efficiency and accuracy.
2. High processing efficiency
The five-axis machine tool can cut multiple faces at the same time, which greatly improves the production efficiency. Moreover, it can complete the cutting of multiple faces through one clamping, avoiding the error of multiple clamping.
3. High precision
Because the five-axis machine has more degrees of freedom, it can better adapt to the cutting needs of complex curved parts, and has better stability and accuracy in the cutting process.
4. Long life of tool
Because the five-axis machine can achieve more directions of cutting, it is possible to use smaller tools for machining. This can not only improve the machining accuracy, but also extend the service life of the tool.
III.The process of five axis machining
1. Parts design
Before five-axis machining, part design is required first. Designers need to make reasonable design according to the requirements of parts and the characteristics of the machine tool, and use CAD design software for 3D design, mainly Coons surface, Bezier surface, B-spline surface and so on.
2. Plan the machining path according to the CAD model, and make the five-axis machining path plan. Path planning needs to take into account the shape, size, material and other factors, and to ensure the smooth movement of the machine tool axes during the cutting process.
3. Program writing
According to the result of path planning, write the code program. The program contains the specific control instructions and parameter Settings of each movement axis of the machine tool, that is, numerical control programming is carried out in the 3D modeling software, and the generated numerical control program is mainly G code and M code.
4. Preparation before processing
Before five-axis machining, it is necessary to prepare the machine. Including the installation of fixtures, tools, measuring tools, etc., and to check and debug the machine tool. After the NC programming is completed, the tool path simulation is carried out to verify whether the tool path is correct.
5. Processing
During the machining process, the operator needs to fix the part on the fixture according to the program instructions, and install the tool. Then start the machine and process according to the program instructions.
6. Testing
After processing, the parts need to be inspected and adjusted. This includes the inspection of size, shape, surface quality, etc., and the adjustment and optimization of the program based on the inspection results.
The German and Japanese brand five-axis processing equipment owned by GPM not only has the characteristics of high precision and high efficiency, but also can realize automatic production, which greatly improves the production efficiency. GPM also has a professional technical team, they are skilled in a variety of five-axis machining technology and software programming, can customize production according to customer requirements, to provide customers with "small-batch" or "full-scale order " parts machining services.
