Process analysis and CNC machining of eccentric sleeves (4)

3 simulation

After the programming is completed, the correctness should be verified. When the machine tool and the tool are not moving, the tool center motion track is drawn on the machine tool or the computer, and the tool center motion track is the same as the actual machining track. The verification mode is analog. There are two ways to simulate. One is to use a special software to simulate on a computer; the other is to input it to the machine and simulate it on the machine. However, the two simulation methods can only simulate the correctness of the tool trajectory, but can not simulate the collision of the tool and the workpiece. The simulation of the eccentric sleeve machining program is performed on the machine tool.

3. Conclusion

In summary, in the processing of the eccentric sleeve, the dimensional accuracy and surface roughness of the eccentric sleeve are ensured through the process analysis and numerical control processing. In the NC program, the use of drilling cycles, hole positions, subroutines, programmable rotation and other techniques greatly simplifies the machining program, and also manually prepares a machining program containing multiple symmetrical uniform figures and multiple uniform holes. Provide a good example and accumulate experience.
