1、 Production process and process flow
1. Production process
The process of converting raw materials into products is called the production process, which mainly includes the transportation of raw materials, storage of raw materials, preparation work before production, pre-processing of raw materials, mechanical processing, surface treatment, assembly, testing, debugging, anti oxidation treatment, and product packaging;
The production process can also be divided into the production process of the entire machinery or the production process of a single component, whether it is a coordinated production process of the entire factory or a production process of a single workshop;
2. Process flow
In the specific production process, the process of directly changing the shape and size of the raw material to the relative position and properties required by the product, making it a finished or semi-finished product, is called the process flow. The process flow is a very important component of the production process, and the main part of the production process in the mechanical processing factory is called the mechanical processing process flow. The main part of the production process in the assembly workshop is called the assembly process flow;
2、 What are the components of the machining process flow
1. Development of processing procedures
The machining process refers to the process in which an operator or a group of operators continuously complete the machining of one or more parts at a fixed workplace or on a fixed machining machine. The machining process is the basic component of the machining process line and the basic unit for arranging production plans;
2. Installation
The part of the process completed by a workpiece or assembly unit after one clamping is called the installation process. Sometimes, in the same process, the workpiece may need to be installed several times to achieve the final goal; It should be noted that during the processing, the number of installations should be minimized as much as possible to reduce installation errors and save more auxiliary time;
3. Work steps
The part of the process that is continuously completed on the machining surface of the part, the tools required for machining, and the constant speed and feed rate is called a step, which is the basic unit that constitutes the process;
4. Workstation
In order to complete a certain process, after one clamping, the workpiece and the movable part of the fixture, including the equipment, occupy every position relative to the fixed part of the tool and equipment. For example, using a indexing head to mill a hexagonal body, each rotation is a workstation;
5. Walking knife
In the same work step, if the machining amount is relatively large, the same tool needs to be used to perform multiple cuts on the same machining surface at the same speed and following the given amount. Each cut is a single tool pass.
