The high-performance 5-axis CNC milling machining center, the CNC system has the space coordinate system rotation and the inclined tool compensation function, which provides the possibility for the machining of some parts that require inclined surface machining and high machining accuracy. When machining on an inclined plane, it is difficult to compile a machining program because the coordinate system changes in space.
Using multiple tools on the machining center machine tool can process all five or six sides of a complex bar workpiece. Its transmission efficiency is significantly higher than that of lathes with additional drive tools. 5-axis milling of bar stock is also economical when machining very small batches of workpieces.
Ordinary CNC milling machines also have a CNC operating system (such as FANUC, Siemens, China Huazhong or Guangshu, etc.), as well as three feed axes and a rotating spindle. Their processing mode geometry is exactly the same, and basically the same processing capabilities can be achieved.
Path simulation of 5-axis high-speed milling
Because the tool path is more complicated during five-axis high-speed milling, and the tool axis vector changes frequently during the machining process. Especially in high-speed cutting, the tool movement speed is very fast, so it is very necessary to carry out the verification and review of the CNC program before the actual product cnc processing.
Before adopting 5-axis CNC machining centers, most turbomachinery manufacturers used 3-axis or 4-axis machine tools to process impellers, and most of them used point machining. That is, every point on the blade surface is processed into a point by the tool tip. When the tool moves along the surface of the blade, it will leave some pits or residual sharp corners, and the height of these pits or sharp corners depends on the programming skills. Point processing is also a feasible method, but this method has some unavoidable disadvantages:
CNC machining holes in the solid part of the workpiece with a drill is called drilling. The drilling is rough machining, the achievable dimensional tolerance grade is IT13~IT11, and the surface roughness value is Ra50~12.5μm. Due to the long length of the twist drill, the small core diameter and poor rigidity, as well as the influence of the chisel edge, the drilling has the following technological characteristics:
5-axis machining of 28 parts at a time
5-axis simultaneous machining of 28 parts
How do you realize the advantages of the five-axis machine? Here is an example of a Haas UMC-750P machine that processes 28 parts at the same time. Through the design of the turntable and the fixture, and the three processing surfaces of the part are combined into one processing program in the five-axis processing program, the purpose of reducing the cycle time is achieved.
What is 5-axis CNC technology? Application of 5-axis machining?
Among the different machining technologies for chip removal that exist, 5-axis machining is one of the most complex.
The 5-axis machining centers have the ability to carry out translations through the X, Y, Z axes; and rotations through two other axes A and B that can be carried out by the table or by the machine head, thus making the tool more accessible to the part to be machined.
