Mechanical manufacturing system and its components

For a long time, people have often looked at various issues involved in the field of machinery manufacturing in isolation. The machine tools, tools and manufacturing processes used in machinery manufacturing have been limited to treating them separately and individually. Research. Therefore, over a long period of time, despite the remarkable achievements of many research and development efforts in the field of mechanical manufacturing, no important breakthrough has occurred in significantly improving the productivity of small batch production. It was not until the late 1960s that people gradually realized that only by treating the various components of mechanical manufacturing as an organic whole, using cybernetics and systems engineering as tools, and analyzing and researching from a systematic perspective, can the mechanical manufacturing process be understood. Implement the most effective control and greatly improve processing quality and processing efficiency. Based on this understanding, many studies and practices were carried out, and the concept of mechanical manufacturing system emerged.

Since the mechanical manufacturing system is regarded as a system, it must have input and output, as shown in Figure 5-1. The input of the so-called mechanical manufacturing system is a certain material or blank, and the output is processed parts, components or products. In a sense, the manufacturing system is a component or subsystem of the production system.

In the material subsystem, blanks, cutting tools, fixtures, measuring tools and other auxiliary materials are input as raw materials, and are finally output as finished products after storage, transportation, processing, inspection and other links. This process is the flow of matter, so it is called material flow. The components responsible for material storage, transportation, processing, and inspection can be collectively called the material system.

In the information subsystem, the operation plan, scheduling and management instructions to be determined for processing tasks, processing sequences, processing methods and material flow belong to the information category and are called information flow. The relevant software and hardware resources responsible for the storage, processing and exchange of this information can be called information systems.

In the energy subsystem, the energy conversion, consumption and processes during the manufacturing process are called energy flow. The relevant components responsible for energy transmission and conversion are called energy systems.

In conventional manufacturing systems, material subsystems and energy subsystems commonly exist, while information subsystems are often lacking. For example, a manufacturing system consisting of an ordinary lathe only has a material system and an energy system, and the input and transmission of processing information is completed manually. However, in modern manufacturing systems, information systems are more commonly added. For example, CNC (computer numerical control system) in CNC machine tools is a typical information system. It can store part processing information through its internal computer and send it. Processing instructions control the processing process.
