What are the characteristics of centralized and decentralized turning milling combined machining processes
Centralization and dispersion of turning milling processes are two different options for the preparation of process routes. The process dispersion is to divide the processing of each surface of the part into very fine parts, with many processes and long process routes. On the contrary, the processing of parts is only concentrated in a few processes, while each process contains a lot of processing content.
1. Characteristics of process concentration
(1) It is convenient to use efficient special equipment and process equipment to greatly improve productivity.
(2) The number of equipment is reduced, and the production area of operators is correspondingly reduced.
(3) The number of processes is reduced, the workload of transportation is reduced, the production planning is simplified, and the production cycle is shortened.
(4) The number of workpiece installation times is reduced, which is not only conducive to improving productivity, but also easy to ensure the mutual position accuracy between them because many surfaces are processed in one installation.
(5) Because the number of special equipment and special process equipment used is large and complex, the adjustment and maintenance of machine tools and process equipment are time-consuming, and the production preparation workload is large.
2. Characteristics of decentralized processes
(1) Simple machine tools and process equipment are used, which is easy to adjust.
(2) Because the process content is simple, it is conducive to selecting reasonable cutting parameters, arranging process time and organizing flow production.
(3) The production preparation workload is small, and it is easy to adapt to product replacement.
(4) Low technical requirements for operators.
(5) The number of equipment is large, the number of operators is large, and the production area is large.
