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:
CAXA wire cutting is a software system for CNC programming of wire cutting machine tools, which has a wide range of applications in the field of wire cutting processing in my country. It can provide fast, efficient, and high-quality CNC programming codes for various wire-cutting machine tools, greatly simplifying the work of CNC programmers. CAXA wire cutting can quickly and accurately complete tasks that are difficult to complete under traditional programming methods.
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.
In the CNC machining of the impeller blades, the machining of large impeller blades is the most difficult. Mastering the measures to solve the processing difficulties of large blades has a very positive effect not only on the large blade itself, but also on the impeller moving blades, impeller stationary blades, guide impeller blades and impeller end blades.
Inclined CNC parts are often encountered in the production process. Need to punch, boring, and milling shapes on the inclined surface. Or it is necessary to process several inclined surfaces with different directions and different slopes in the same clamping, and each inclined surface has a higher geometric tolerance requirement.
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.
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.
