Introduction to the knowledge of mechanical parts processing that we do not understand.

The processing of mechanical parts is an important task for mechanical processing plants and has become one of the operation contents of mechanical processing plants. Previously, I have introduced the relevant content of mechanical processing to you, but those are just a very small part.

The processing of mechanical parts is an important task for mechanical processing plants and has become one of the operation contents of mechanical processing plants. Previously, I have introduced the relevant content of mechanical processing to you, but those are just a very small part. There is still a lot for us to understand and learn, because the knowledge it contains is extremely rich. Only by continuous learning can we deepen our understanding. Now, let's elaborate on it specifically.

1. Production Process

It refers to the process of transforming raw materials or semi-finished products into products. It includes the following aspects:

The technical preparation process refers to activities such as market research and prediction, identification of new products, process design, and standardization review carried out before the product goes into production.

The process specification is the process of compiling a reasonable and correct process into a technical document to guide production, which is specifically turned into written instructions.

Auxiliary production refers to normal auxiliary production activities, and these production activities are carried out to ensure the smooth progress of production activities.

The production service process includes the organization, transportation, storage, and preservation of raw materials, as well as the sales and packaging of products.

2. Technological Process

Here it refers to the cutting processing of parts, which contains many processes. Each process includes workstations, machining steps, and tool passes, etc. The basis for division is the working location and continuity. In a process, the machining step is the basic unit that constitutes the process.

What is a tool pass? Simply put, it is to remove the allowance from the machining surface of the workpiece. However, the allowance removed should not be too much. If it cannot be completed in one step, it can be carried out in several steps.

In the technological process, each machining position is called a workstation. In most cases, in one process, the workpiece is only installed once, but sometimes it may be installed multiple times.

3. Formulation of Process Specification

It includes the requirements, steps, and requirements for formulating the process specification. Generally speaking, it should be economical and reasonable.

The steps for formulating the process specification are as follows: First, determine the machine tools, clamping methods, measurement methods, machining allowances, cutting parameters, and man-hour quotas used in each process, etc. Then record these contents in a certain form and make mechanical processing process cards for operators to refer to.
