Scheme planning method of reconfigurable manufacturing process

Abstract

The invention provides a scheme planning method of a reconfigurable manufacturing process, comprising the following steps of: forming natural combining procedure unit sets through establishing machining information matrixes; combining the natural combining procedure unit sets to form a plurality of different procedure unit plans and integrating into different work procedure section combining schemes; then carrying out bidirectional crossed combination on work procedure section schemes to form a plurality of machining process schemes of different parts; and finally, formulating the reconfigurable manufacturing process facing to part cluster machining. According to the scheme planning method disclosed by the invention, the machining process schemes of the different parts are formed through establishing a machining information matrix, combining procedure units and establishing work procedure sections, and the reconfigurable manufacturing process facing to the part cluster machining is formulated; the rapid conversion of a machining function of a reconfigurable production line is realized and the scheme planning method combines advantages of a special machine production line and a flexible production line; and the contradiction of efficient and low-cost machining and production flexibility in existing batch machining is effectively solved, and the scheme planning method of the reconfigurable manufacturing process has very important effect on the popularization and the application of reconfigurable manufacturing.

Description

technical field [0001] The invention belongs to the technical field of mechanical manufacturing, and relates to a planning method for a part processing technology scheme with stylized operations, in particular to a reconfigurable manufacturing technology scheme planning method for batch processing. Background technique [0002] At present, there are two main types of equipment used in batch processing: one is a special production line composed of special planes, which are custom-designed for a certain part processing process, have no redundant functions, low investment costs, and can be multi-tool / multi-spindle at the same time Processing has the advantages of high efficiency and low cost. Its biggest defect is that it is difficult to cope with changing product processing requirements. Therefore, the special machine production line is only suitable for mass production of a single variety. At present, the special machine production lines of many automobile and tractor manufact...

Problems solved by technology

[0002] At present, there are two main types of equipment used in batch processing: one is a special production line composed of special planes, which are custom-designed for a certain part processing process, have no redundant functions, low investment costs, and can be multi-tool / multi-spindle at the same time Processing has the advantages of high efficiency and low cost. Its biggest defect is that it is difficult to cope with changing product processing requirements. Therefore, the special machine production line is only suitable for mass production of a single variety. At present, the special machine production lines of many automobile and tractor manufacturers are facing product changes. type of difficulty

The second is a flexible production line composed of machining centers (or CNC machine tools), which has many functional reserves and can meet different processing needs, but the investment cost is high; due to the use of single-tool sequential processing, it lacks the low-cost and high-efficiency processing advantages of special-purpose production lines; For batch processing, the processing plan of the processed parts does not change much, resulting in a low utilization rate of the flexible production line, resulting in an increase in processing costs

With the uncertain changes in market demand and global competition, the traditional batch production of a single product is also rapidly developing in the direction of variable batches and varieties. It is difficult to solve the problem of high-efficiency and low-cost processing in current batch processing by using traditional special-purpose production lines or flexible production lines.
