How to reduce the scrap rate in machining processes

Confirmation of drawing requirements 

The drawings contain various machining requirements such as dimensional requirements, behavioural tolerances, roughness requirements, heat treatment requirements and so on. This information is clear on the drawings, but of course given the design capability of the design engineer, there may be areas where these requirements have been omitted, and this is where a seasoned mechanical process engineer is needed to keep an eye on things. For example, for the product drawings, assembly and use of the product drawings to do a certain degree of thinking, the design engineer missed the part to make up, this is actually a product continuous improvement process. 


Confirmation of process content 

The process flow of the part is an important basis for the implementation of our machining steps, but also an important guarantee of the quality of the processing of parts, in fact, many mechanical process engineers' professional core competence is also reflected in this place. How to design the machining process of a part correctly, reasonably, cost-effectively and with high quality is the highest expression of the professional ability of a bullish process engineer. 


Ensure the ability of equipment 

In fact, the processing quality of a mechanical part comes to a large extent from the processing accuracy of the processing equipment. We usually call it "workhorse" in professional terms, especially for some high-precision parts processing, which is beyond the reach of human beings and can only be completely handed over to the equipment to ensure.


 The right machining method

 The choice of the correct machining method, which is actually mentioned in the previous point on equipment selection, is based on the processing capacity of the equipment and the processing method to choose the correct processing mode. So in the processing mode of choice, we need to consider the surface is a lot of, roughly from these aspects "processing accuracy, processing quality, processing costs, processing efficiency, enterprise equipment resources" and so on. 


A positive attitude to work

 Finally, we would like to return to the people, because the upper limit of a part's processing quality may be determined by the equipment. But the quality of a batch of parts must be determined by people, because if the equipment is not working, you can find and adjust it. If the workers do not have a proper and good attitude towards machining, then the quality of the machining of the parts will not be possible. 


For the current utilitarian society, it is actually very difficult to regulate the attitude of workers, and many seemingly unreasonable quality accidents become so reasonable after some justification, which is really unexpected, so it is very necessary for enterprises to provide appropriate professional ethics education and professional training for employees. This balance cannot be left to the conscience of the workers, but should be left to systems and regulations.
