The main features of machinery manufacturing production
The main features of the machinery manufacturing industry are: dispersion-based, process-assisted, and assembly-focused.
The characteristics of industrial production are basically divided into two major ways: discrete type and flow type. Discreteness refers to the way in which final products are made up of individual parts. Because the final production of its finished products is based on the assembly of components as the main process, so the assembly has become a natural focus. The process type refers to the fact that the final finished product is formed differently from the discrete components, but by changing the shape or chemical properties of some raw materials, the new shape or new material is finally produced. the way. The manufacturing of mechanical equipment we are familiar with is a typical discrete industry, while smelting is a typical process industry. The automotive industry traditionally considers it to be a discrete industry. Although such processes as die casting and surface treatment belong to the category of process flow, most of the processes are still characterized by discreteness. Therefore, machinery manufacturing is not an absolute discrete industry, but there are still some process-oriented features. Specific features are the following:
(1) Clear and clear product structure
The product structure of a machinery manufacturing company can be described by the concept of a tree. The final product must be composed of a fixed number of parts or components. These relationships are very clear and fixed.
(2) Simple and clear process flow, flexible process route, difficult coordination of manufacturing resources
The order-oriented machinery manufacturing industry is characterized by multiple varieties and small batches. Therefore, the layout of production equipment for machinery manufacturing is generally not arranged by product but according to process, for example, by arranging the machine tools by car, grinding, planing and milling. position. The process of each product may not be the same, and there are multiple machines that can perform the same process. Therefore, the processed material needs to be scheduled and the intermediate product needs to be carried. Discrete manufacturing for mass production in inventory, such as the automotive industry, etc., arranges production equipment according to the process.
(3) Easy and convenient material storage
The raw materials for the machinery manufacturing enterprises are mainly solid, and the products are also solid in shape. Therefore, the storage is mostly an indoor warehouse or an outdoor open warehouse.
(4) Relatively low level of automation
Machinery manufacturing enterprises are mainly discrete processing. The quality and productivity of products depend largely on the skill level of the workers. Automation is mainly at the unit level, such as CNC machine tools and flexible manufacturing systems. Therefore, the machinery manufacturing industry is also a personnel-intensive one. Industry, the level of automation is relatively low.
(5) Difficulties in the formulation of production plans and management of production tasks
Typical discrete machinery manufacturing companies are mainly engaged in single-piece and small-batch production, and the product process often changes. Therefore, good planning is required. Since production is mainly organized on an order basis, it is difficult to predict when an order will arrive. Therefore, planning for purchasing and production workshops requires a very good production planning system, and especially computers are required to participate in the work of the planning system.
