How do we optimize the design?
1. First of all, we must ensure the feasibility of processing
Many designers do not consider the processing technology when designing the drawings. Although the drawings are beautiful in design, they cannot be processed by mechanical processing. At this time, they need to modify the drawings to make them suitable for mechanical processing. (Different from 3D printing, 3D printing can be made as long as there are three-dimensional drawings)
2. Consider saving processing costs
There are some drawings of the design, because some small details are not considered too well, which will increase the processing cost a lot. For example: some inner right angles, in fact, the milling cutter can not be processed, and can only be done by EDM. If the customer can If it is changed to rounded corners, we will recommend the customer to change it. There are also some unnecessary rounded corners. If it is just for the purpose of not cutting hands, we will recommend that customers change to beveled corners. (Corner C)
3. Ensure good coordination of all parts
Usually the parts are not used alone, so when we get the drawing, we usually communicate with the customer how to assemble or what it is used for, so that we can better understand what tolerances and tightness are suitable for this product. If we find that there is a problem with the matching of two parts, such as the diameter of the hole is 30, but the diameter of the column is also 30, we will provide the customer to adjust the size to facilitate the assembly of the two parts.
4. Other optimization suggestions
Because our engineers are very professional, there may be other suggestions, such as materials, such as surface treatment, we will give the best suggestions we feel according to customer requirements for you to adopt.
