What are the technological advantages and difficulties of the walking machine in processing complex shaped parts

In the field of modern mechanical processing, the demand for high-precision machining of complex shaped parts is increasing day by day. As an advanced CNC machining equipment, the walking machine exhibits unique advantages in processing complex shaped parts such as slender shafts and irregular parts, but also faces some challenges.

The process advantage of the walking machine in processing such parts is significant. Firstly, the walking machine has high-precision linear and rotational motion control capabilities. This ensures that the straightness and cylindricity of the shaft meet high precision requirements when processing slender shafts. For example, in the manufacturing of slender transmission shafts in precision instruments, the walking machine can effectively control the radial runout and axial displacement of the shaft, thereby ensuring the smoothness and accuracy of the transmission.

The high-speed cutting capability of the walking machine is also one of its advantages. When processing complex shaped parts, it can quickly remove materials and improve processing efficiency. Meanwhile, high-speed cutting generates relatively less heat, which helps to reduce thermal deformation of parts and further ensure machining accuracy.

However, when machining complex shaped parts, it is not always smooth sailing and there are some difficulties. Firstly, for the machining of slender shafts, due to their large aspect ratio and weak rigidity, bending and vibration are prone to occur during the cutting process. This requires careful selection of cutting tools, cutting parameters, and process routes to reduce the impact of cutting forces on the shaft.

The processing of irregular parts often requires complex tool path planning and programming. This requires programmers to have rich experience and advanced skills to ensure that the tool can accurately cut according to the predetermined trajectory, avoiding the occurrence of overcutting or undercoutting.

Furthermore, the wear and replacement of cutting tools during the machining process is also a key issue that needs to be closely monitored. The machining of complex shaped parts usually requires long-term continuous cutting, and the cutting tools are prone to wear. Frequent tool replacement can also affect the stability of machining efficiency and accuracy.

In addition, the selection of materials and heat treatment processes also have a significant impact on the machining quality of complex shaped parts. Inappropriate materials or heat treatment processes may cause defects such as deformation and cracks in the parts during the machining process.

In summary, the walking machine, with its advantages of high precision, multi axis linkage, and high-speed cutting, can meet the needs of many high-end manufacturing fields when processing complex shaped parts. However, at the same time, it is also necessary to overcome difficulties such as the rigidity of slender shafts, the programming complexity of irregular parts, tool wear, and material handling. With the continuous advancement of technology and optimization of processes, it is believed that walking machines will play a more important role in the processing of complex shaped parts, providing stronger support for the development of the manufacturing industry.
