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.
CNC machining has become a major pillar of the manufacturing industry. This type of processing is used in more and more products (for example, CNC turning and CNC milling, engraving, cutting and drilling). Although many mechanics are accustomed to this form of processing, not everyone knows the logic behind it. Compared with other forms of machining, the main advantages of using CNC machining are as follows:
In the process of CNC machine tool parts processing, the accuracy of the parts processed directly affects the quality of the product itself. Some mechanical parts and compact equipment parts have very high requirements for machining accuracy. Improving the machining accuracy of CNC machine tools is the key to the problem. Through comparative research and analysis, the following countermeasures can be adopted:
Virtual reality, as a new high-tech technology, has been widely used in many fields such as aviation, aerospace, and manufacturing. An important application of this technology is the simulation of some phenomena in the manufacturing industry. The most typical is the simulation of CNC machining process. At present, simulation technology based on surface modeling and solid modeling has been widely used in CNC simulation, and there are also good algorithms for single-sided machining simulation of three-axis CNC milling machines.
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.
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:
With the increase in the design of multi-faceted and complex curved parts, 5-axis machining will account for an increasing proportion of CNC machining. Because 5-axis CNC machining adds two degrees of freedom of rotation, it increases the difficulty of CNC machining motion simulation calculation and tool interference checking, especially when machining parts with extremely complex shapes.
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.
There are many reasons for the deformation of machined aluminum parts, which are related to the aluminum material, the shape of the part, and the CNC machinery and equipment. There are mainly the following aspects: blank internal stress, cutting force, deformation caused by cutting heat, and deformation caused by clamping force.
