Principle of CNC Rapid prototyping (prototyping CNC machining)

There are several common processes for making
rapid prototyping :CNC machining, 3D printing, vacuum casting, sheet metal, and so on.

Today we will briefly describe the steps and advantages of CNC machining.
Rapid prototyping, many people also called the first sample.
Generally speaking, after the design of an industrial product is completed, it is not put into production immediately, but a small number of models should be made according to the drawings. The purpose is to see the samples of the finished products in advance. If you are not satisfied with the design, you can modify the drawings until there is no objection, and then start mass production.
And this little model, is also the rapid prototyping.

The steps of CNC machining processing are as follows:
1) Negotiate CNC processing price and delivery date, and sign the processing contract.
2) Analyze the parts drawing and product assembly drawing, and analyze the process of the parts.
3) Select blank.
4) CNC programming.
5) Determine the machining allowance of each procedure, calculate the dimension and tolerance of each procedure.
6) Determine the equipment, cutting tools, fixtures, measuring tools and auxiliary tools used in each process.

7) Determine cutting parameters and working hours.
8) Determine the technical requirements and inspection methods of each major process.
9) Fill in the CNC proofing process documents.

There is no need for complex fixtures.
If you want to change the shape and size of the part, you only need to modify the part processing procedure, suitable for new product development and modification.
Zhongda processing quality is stable, high processing precision, high repeatability, to meet the processing requirements of high-precision products.
In the case of mass production, the production efficiency is higher, can reduce the production preparation, machine tool adjustment and process inspection time.
(4) can be processed by conventional methods difficult to process complex surface, and even can be processed some can not observe the processing parts.
