[Abstract]:In order to make the shape deposition manufacturing flexible, the concept of the similar flexible shape deposition manufacturing system is put forward. Based on this concept, the overall structure, equipment layout, deposition equipment scheduling of the system are discussed in this paper. The structure characteristics of workpiece logistics system and the control system are studied. The main contents are as follows: (1) the overall framework of the system is established and the roles and relationships of each module in the framework are described in detail. According to this general framework, based on the study of the structure layout of the core deposition-material deposition equipment in the system, the general layout of the similar flexible shape deposition manufacturing system is planned. The overall structure and the overall layout constitute the structure model of the similar flexible shape deposition manufacturing system. (2) the theory of flexible manufacturing is applied to the shape deposition manufacturing system. The general layout of the depositional station is put forward, the dispatching of the depositional station, the overall structure of the fixed platform and the installation of the deposition equipment are presented. The structure of deposition equipment scheduling, fixed platform and other auxiliary devices are studied and discussed, and the working process of deposition station in this form is described in detail. The structure of the deposition station is the core of the similar flexible shape deposition manufacturing system, through which the deposition equipment can be added or removed flexibly, and together with other process devices, the similar flexible shape deposition manufacturing system can be constructed. (3) the manufacturing processes of shape deposition are regarded as independent manufacturing units, and each manufacturing unit is connected organically through the workpiece logistics system. The structural characteristics and working mode of material deposition equipment and workpiece logistics device in the system are discussed in detail, and their working processes are described. These studies have laid a foundation for the formation of a specific flexible shape deposition manufacturing system. (4) aiming at the flexible shape deposition manufacturing system, the overall control scheme of the system is established, and the control mode, data transmission route and monitoring method between the upper and lower computers in the system are described. According to the control scheme and the function, structure form and working process of each component in the flexible shape deposition manufacturing system, the concrete control objects of each part are defined, and the main controller and the dispatching system of the deposition station are analyzed. The control flow chart of each sub-station controller such as system constitution equipment, workpiece conveying system and so on is discussed. The relationship between the components of the control flow chart and the control process are discussed, which lays a foundation for the design of the concrete control system.
