The overall composition framework can be divided into three stages from the information flow direction: the first stage is a flexible complex material increasing/decreasing hybrid manufacturing system process planning subsystem, the second stage is a flexible complex material increasing/decreasing hybrid manufacturing system control subsystem, and the third stage is flexible complex material increasing/decreasing hybrid manufacturing system hardware composition equipment.
The first stage is a flexible complex additive/subtractive hybrid manufacturing system process planning subsystem that receives input of relevant production data from production orders and job planning using a human-machine interface, while the system supports process system upgrades and the addition of new processes. The following data can be output through the operation of the system: a) planning data of a multi-head mixed deposition process series: the deposition method comprises the following steps of (1) selecting the deposition mode, such as mixed deposition, single material deposition, serial deposition, parallel deposition, general structural member deposition, complex structural member deposition, processing sequence data of when the exchange between multiple deposition heads is started, and the like; b) deposition process planning data: based on the deposition mode data, the deposition process planning data is the deposition material (material and type), the number of deposition nozzles, the energy mode and the like; c) deposition of workpiece layer data: decomposing a three-dimensional part into layered data suitable for flexible complex deposition according to the structure and the processing mode of the part; d) deposition of workpiece layout planning data: meanwhile, the number of deposition workpieces, the arrangement on a workbench, the number of adopted deposition heads, the number of corresponding manipulators and the like are increased; e) material removal process data: the method is characterized in that the method adopts a removal process, namely material removal is carried out by using a three-axis numerical control device of a general structural member, material removal is carried out by using a five-axis numerical control device of a complex structural member, and data such as the type of a tool is adopted; f) planning data of additive/subtractive mixed process series: refers to process sequence data as to when an exchange between material deposition and material removal is to begin.

After the subsystem is finished, the subsystem is ready for processing, and simultaneously, the system supports system upgrading and system maintenance.
As shown in fig. 1, the third stage is a hardware component device of the flexible complex additive/subtractive material hybrid manufacturing system, which receives various control data from the control subsystem of the flexible complex additive/subtractive material hybrid manufacturing system, and allows the devices of the system to work together to perform additive/subtractive material hybrid processing on the manufacturing layer, and finally output the processed workpiece (with the deposition disk). The subsystem also requires space for equipment maintenance, addition, and modification.
Based on the data outputted from the flexible complex additive/subtractive material hybrid manufacturing system process planning subsystem shown in fig. 1, the further analysis can obtain the flexible complex additive/subtractive material hybrid manufacturing system process planning subsystem shown in fig. 2. The overall working mode is as follows: firstly, an order management module receives a production order and a part drawing, including part processing information, and then gives information such as a scheduling plan and production time through order management. The intelligent process planning module automatically plans process regulation data including deposition modes, mixed processing process conversion series and the like based on the system equipment information and the process data according to the operation plan information and gives estimated processing completion time.
