What is processing technology and how to make process steps?

Machining technology refers to the whole process of making the shape, size, relative position and performance of the blank into qualified parts by traditional machining methods according to the drawings and sizes. Processing technology is the work that workers need to do before processing to avoid processing errors and economic losses.

Machining process is a step of manufacturing workpieces or parts. The process of directly changing the shape, size and surface quality of the blank to make it a part is called machining process. For example, the processing flow of an ordinary part is rough machining-finish machining-assembly-inspection-packaging, which is a general processing flow.

Machining technology is to change the shape, size, relative position and properties of the production object on the basis of technology, so as to make it a finished product or a semi-finished product. It is a detailed description of each step and each process. For example, as mentioned above, rough machining may include blank manufacturing, polishing, etc. And finishing can be divided into lathe, fitter, milling machine, etc. And each step should have detailed data, such as how much roughness and tolerance to achieve.

Technicians determine the technological process to be adopted according to the quantity of products, equipment conditions and workers' quality, and write relevant contents into technological documents, which are called technological procedures. This is more targeted. Every factory may be different, because the actual situation is different.

Generally speaking, the process flow is the program, the processing technology is the detailed parameters of each step, and the process specification is the specific processing technology compiled by a factory according to the actual situation.

Processing process:

Machining process specification is one of the process documents that stipulate the machining process and operation method of parts. Under specific production conditions, reasonable processes and operation methods are written into process documents in a specified form, which are used to guide production after approval. The specification of machining process generally includes the following contents: the process route of workpiece processing, the specific content of each process and the equipment and process equipment used, the inspection items and methods of workpiece, cutting dosage, working hour quota, etc.

Steps for formulating process regulations:

1) Calculate the annual production plan and determine the production type.

2) Analyze part drawings and product assembly drawings, and analyze the process of parts.

3) Select blank.

4) Draw up the process route.

5) Determine the machining allowance of each process, and calculate the process size and tolerance.

6) Determine the equipment and tools, fixtures, measuring tools and auxiliary tools used in each process.

7) Determine the cutting quantity and man-hour quota.

8) Determine the technical requirements and inspection methods of each major working procedure.

9) Fill in the process documents.

In the process of making process regulations, it is often necessary to adjust the contents that have been preliminarily determined in front to improve economic benefits. During the implementation of the process plan, unexpected situations may occur, such as changes in production conditions, introduction of new technologies and processes, application of new materials and advanced equipment, etc. It is required to revise and improve the process plan in time.
