It is a good question, many product designer have to meet and solve this problem. The genius designer will give you a perfect parts that can not be be realized some time. Now i wanna talk about how to design a good component from CNC machining side.
First, you need to know the part processability
The processability of the part structure refers to the ease of processing the parts of this structure.Parts are both usable and technical.
Evaluation of the design of parts should not be biased towards usability.The quality of the process is relative. With the advancement of science and technology, parts that were originally considered to be poorly crafted may no longer be difficult to process.
Machining of mechanical parts
Machining is the primary means by which a part can achieve the desired structural shape, dimensional accuracy and surface quality.
Usually the labor and cost of cutting is the highest. Therefore, the process design of the cutting structure of the part is particularly important.In order to make the parts have better machining process structure, the following principles should be considered in the structural design:
1. Standardized parameters should be used as much as possible;
2. The structural elements of the parts should be as uniform as possible;
3. Consideration should be given to the convenient clamping of the parts;
4. The through hole is better than the non-through hole, and the outer surface is better processed than the inner surface.The plane is better than the step surface, the straight hole is better than the inclined hole, and the rigidity is good and the processing is good;
5. The surface to be precision processed is as small as possible, so that the surface area to be processed is small;
6. In order to facilitate the processing of the part, the part can be considered Reasonable splitting and combination;
7. On the basis of meeting the requirements of use, try to reduce the machining accuracy and surface quality requirements of the parts;
8. The structure of the parts should be compatible with advanced processing methods.
