Foundation: application of FMS

I. composition of FMS

a typical FMS is composed of digital control processing equipment, material storage and transportation system and information control system. In order to realize the flexibility of the manufacturing system, the airlift membrane separation equipment composed of FMS must include the following components

(I) processing system

the equipment used in the flexible manufacturing system is determined by the type of workpiece to be processed, mainly including machining center, turning center or computer numerical control (CNC) turning, milling, grinding and gear processing machine tools, which are used to automatically complete the processing of various processes

(II) material system

the material system is used to realize the automatic supply and loading and unloading of workpieces and tooling fixtures, as well as the automatic transmission, transportation and storage between processes, including various conveyor belts, automatic guided carts, industrial robots and special lifting conveyors

(III) computer control system

the computer control system is used to process all kinds of information of the flexible manufacturing system and output the information required to control the automatic operation of CNC machine tools and material systems. Generally, three-level distributed computer control system (developing high molecular material equipment level, workstation level, unit level) is adopted, in which the unit level control system (unit controller) is the core of flexible manufacturing system

(IV) system software

system software is used to ensure that the flexible manufacturing system can effectively adapt to the management, control and optimization of small and medium-sized batch and multi variety production, including design planning software, production process analysis software, production process scheduling software, system management and monitoring software

II. Classification of flexible manufacturing system

according to the size, FMS can be divided into the following three categories

(I) flexible manufacturing unit (FMC)

FMC is composed of a single machining center with a multi pallet system or less than three CNC machine tools, which has the flexibility to process a variety of products. FMC has the highest flexibility

(II) flexible manufacturing line (FML)

flexible manufacturing line FML is a production line between non flexible automatic line and FMS. The flexibility requirements of material system are lower than FMS, but the production efficiency is higher

(III) flexible manufacturing system (FMS)

FMS usually includes more than 3 CNC machine tools (or machining centers), which are connected by a centralized control system and a material system, and can realize the processing management of multiple varieties, small and medium batches without stopping the machine. FMS is the most representative manufacturing automation system using flexible manufacturing technology

III. The utility of flexible manufacturing system

the main technical and economic effects of using FMS are: according to the needs of assembly operations, the processing of required parts can be arranged in time to achieve timely production, so as to reduce polyurethane: lightweight materials, rising stars, less inventory of blanks and products in process, and the corresponding amount of working capital, and shorten the production cycle; Improve the utilization rate of equipment and reduce the number of equipment and plant area; Reduce the direct labor force, and realize the continuous "unmanned production" 24 hours a day and night under the condition of few people; Improve the consistency of product quality

IV. development direction of flexible manufacturing system

the development direction of flexible manufacturing system will be:

(I) accelerate the development of flexible manufacturing units and small FMS with various process contents

because the investment of FMC is much less than that of FMS and the effect is similar, it is more suitable for small and medium-sized enterprises with limited financial resources. The development trend of applying FML in multi variety and mass production is to replace general machining centers with low-cost special NC machine tools

(II) improve the automation function of FMS. The work content completed by FMS has expanded from simple machining in the early stage to comprehensive fields such as welding, assembly, inspection, sheet metal processing and even casting and forging. In addition, FMS should also be combined with computer-aided design and manufacturing technology (cad/cam) to develop in the direction of overall automated factories. (end)
