Surface quality study of automotive parts

2022-12-12


Surface quality and cutting technology is an important research content of microfabrication technology, scholars have carried out in-depth research work in this area, and has achieved a large number of research results. However, microfabrication technology is a kind of beginning in the 1990s, its development time is still very short, in the processing quality and cutting technology there are still some problems to be studied in depth, which is mainly reflected in:

(1) in the choice of materials, the current microfine cutting technology on aluminium alloy, copper alloy, PMMA and other easy-to-machine materials has been quite mature, and has been used in industrial applications. However, as a large number of steel materials used in engineering, especially stainless steel, high strength and high hardness steel and other hard-to-cut metal materials, microfabrication research is still in its infancy.

(2) in the surface quality research, in the evaluation of the surface quality of the machined surface indicators, scholars from various countries on the surface roughness of the research is more in-depth, but for other indicators, such as the surface layer of work hardening, the surface layer of the organisational changes in less research, and these indicators for the processing of the surface quality of the surface of a very significant impact.

(3) in process research, after decades of research, scholars in various countries in the microfabrication of single-form surface machining process capability research has made great achievements, but for specific parts of the microfabrication of cutting process route development, tool path planning and other aspects of the research is not much.

How to increase the excellence of auto parts machining?

First, to choose to engage in machining work technology good staff. There is no excessive technology, difficult to do a good job of machining, we all know that mechanical parts processing is not tolerate shoddy. In the process is also difficult, even if you can do a good job, can spend a lot of time, if the beginning did not start a good head, it will be easy to lose the effort, the effectiveness of the loss is not worth it.
