Introduction to the Basis of Machining Technology

Machining process basis generally includes three aspects: production process, production type and process planning. In the following content, mainly around these three aspects, I hope to help you:

1. Machining production process:

1. The production process of machines refers to the whole process of making products from raw materials (or semi-finished products). For machine production, it includes transportation and preservation of raw materials, preparation of production, manufacturing of blanks, processing and heat treatment of parts, assembly, debugging of products, painting and packaging, etc. The content of production process is very extensive. Modern enterprises use the principles and methods of system engineering to organize production and guide production. The production process is regarded as a production system with input and output.

2. In the process of production, the process of changing the shape, size, location and nature of the production object into finished or semi-finished products is called process. It is the main part of the production process. Process can also be divided into casting, forging, stamping, welding, mechanical processing, assembly and other process. Mechanical manufacturing process generally refers to the sum of parts processing process and machine assembly process. Other processes are called auxiliary process, such as transportation, storage, power supply, equipment maintenance. And so on. The process is composed of one or several sequential processes, and one process has several steps.

3. Procedure is the basic unit of the process of mechanical processing. The so-called process refers to a (or a group) of workers, in a machine tool (or a workplace), on the same workpiece (or at the same time for several workpieces) which part of the continuous completion of the process. The main feature of a working procedure is that it does not change the object, equipment and operator of the processing. The content of the working procedure is that the continuous completion of the working step is a tool-walking or working stroke under the condition of the same surface, tool and cutting parameters. It is a working step completed by the processing tool at one time on the surface of the processing.

2. Types of machined production:

Production types are usually divided into three categories:

1. Single-piece production: Production of products of different structures and sizes individually, with little repetition.

2. Mass production: The same products are manufactured in batches in a year, and the manufacturing process has certain repeatability.

3. Mass production: The number of products manufactured is very large, and most workplaces often repeat the process of a certain part.

3. Principles of process planning:

1. The designed process regulations should ensure the processing quality of machine parts (or the assembly quality of machines) and meet the technical requirements specified in the design drawings.

2. High productivity should be achieved in the process so that products can be put on the market as soon as possible.

3. Try to reduce the manufacturing cost.

4. Attention should be paid to reducing the labor intensity of workers and ensuring production safety.
