The so-called five-axis linkage actually refers to the simultaneous coordinated movement for processing under the control of the computer numerical control (CNC) system. The five-axis linkage machine tool is an important processing technology in our CNC industry. Its processing technology is difficult, its technical content is high, and its programming is also very difficult. More importantly, its mechanic precision is also very high. To a certain extent It is difficult to operate! And for those beginners, this is undoubtedly a very difficult thing to do, you still have to learn from the basics! There are also some due to the uneven quality of the operators, and the ensuing processing out-of-tolerance and damage to the machine tool occur from time to time. So for beginners, what problems should we pay attention to before operating five-axis linkage cnc machining? Next, let me give you a brief introduction.
1. Improve programming skills
Programming is a crucial link in NC machining, improving programming skills can largely avoid some unnecessary collisions.
2. Use the lock function of the machine tool
After entering the program, lock the Z-axis, and judge whether there will be a collision through the coordinate value of the Z-axis.
3. Use the dry run function of the machine tool
After the program is input into the machine tool, the tool or workpiece can be loaded, and then the dry run button is pressed. At this time, the spindle does not rotate, and the workbench automatically runs according to the program trajectory. At this time, it is possible to find out whether the tool may collide with the workpiece or fixture.
4. Using computer simulation system
With the development of computer technology and the continuous expansion of NC machining teaching, there are more and more NC machining simulation systems, and their functions are becoming more and more perfect.
