Avoid "Over-Engineering" In Machining Parts Design

DALIAN, China - Sept. 19, 2022 - PRLog -- Over Engineering And Under Engineering

It is not difficult to recognize that the product design is insufficient, and it is usually completed during the test according to the verification and validation standards. Poorly designed products can be dangerous because not all specified system requirements are met and one or more system elements are not yet available.

But what about over engineering? Over engineering products may also fail due to over engineering. We have implemented one or more unnecessary system components, which may fail or increase unnecessary costs during production and processing. After all, the more complex the workpiece, the more process flow and the higher the cost.

Avoiding Over-engineering Machined Parts

Customers use our CNC machining services, including milling and turning functions, for rapid prototyping and small volume production of end-use plastic or metal parts. Here are some key processing challenges to consider.

Avoid Unnecessary Surface Treatment

For customers in the development / prototyping stage, this is mainly a problem. They want their parts to look flawless, so they need a high level of polishing. However, because it is a prototype, this part is not really ready for public use, so the appearance is not so important. It is true that sometimes the designer does need to show the prototype to the company manager or potential investors, so the parts need to be highly completed, but usually at this stage, it is not necessary to do so.

In sans machining, all parts will be processed by grinding machine to ensure that the finish of the parts is about 0.4. If a higher finish is required, the cost will increase. Therefore, it can be determined whether a higher finish is required according to actual needs.

Avoid Excessive Tolerance

This usually happens when customers require their reaming to have a particularly strict tolerance, even if the corresponding locating pin does not require that level of tolerance or accuracy. Don't over engineer it, or, if you like. We recommend using standardized tolerances for machined parts. At sans machining, the tolerance of our standard prototype and production processing is + / – 0.1mm. If there are requirements for tolerance, it can be marked on the drawing. Remember not to over formulate high tolerance, because it will greatly increase the production cost.
