Организация мелкосерийного производства деталей на принципах модульной технологии

Abstract

It is emphasized that the traditional job shop production is characterized by low efficiency due to the use of superuniversal machining facilities for their underemployment of performance capabilities at work and also low-productivity of process flowsheet when machining part surfaces as a sequential surfaced job, the organizational form of production in the form of sections by type of machine tools, i.e. a section of lathes, a section of milling machines, etc. It results in large travel length of workpieces in the machining process at work. The desire to increase the efficiency of production by organizing launch of batch workpieces that are formed in a constructive similarity, such as structures, parts of rotation body types, etc., does not have a significant effect, because the task is just minimizing the run time spent on changing fixtures and reinstalling workpieces, but not taking into account an optimal sequence of parts in the batch. For increasing the efficiency of small-scale production, the module technology is proposed. The main idea of it is to represent the part not as a network of separate surfaces, but as surface modules, where the surface module is understood as a combination of surfaces and the part performs its proper function with the help of this module. This enables a good specialization of workplaces that are organized not for processing methods, but for manufacturing the appropriate groups of surface modules. The latter make it possible to take advantage of a more productive process flowsheet for machining part surfaces. It is sequential parallel surface job that is used. When organizing production, it becomes possible to use the layout of workplaces in line according to the in-line method, which will significantly reduce the part travel length at workplaces.
