A method for repairing a composite structure is provided. A rework zone is defined on the composite structure. A theoretical scarfing bottom surface is identified for the rework zone from a model of the composite structure. An actual scarfing bottom surface in a local axis system is identified for the rework zone. Parameters for a rework program for an automated scarfing tool are modified based on deviations between the theoretical scarfing bottom surface and the actual scarfing bottom surface. Plies in the rework zone are removed using the automated scarfing tool.

A method for the machining of workpieces (11) and inspection of the processed workpiece surface in a machine tool (1), preferably a die sinking electrical discharge machine. The method uses at least one machining process interruption during which the processed surface of the workpiece (11) is inspected. Within said machining process interruption, at least one image of the processed workpiece surface is captured on the machine tool (1) by means of a digital camera (12). The images are processed by one or two pattern recognition algorithm (PRA D, PRA S), which were previously trained to determine the surface characteristics such as roughness parameters, functional surface features and/or characteristic defects of the processed workpiece surface captured on that at least one image. The determined surface characteristics are used to resume the processing of the workpiece surface with or without adjusting the processing parameters.

A method and system for optimal control of ultra-precision cutting. The method for optimal control is based on time-precipitates-temperature characteristics of AlMgSi series aluminum alloy, and includes first determining types of precipitates of machined materials, and establishing a Lifshitz-Slyozov-Wagner (LSW) model of each precipitate. A temperature range is determined corresponding to each precipitate according to the LSW model to obtain a comprehensive temperature range. A relation model is established between cutting parameters and a cutting temperature according to the LSW model. Finally the cutting parameters are optimized according to the comprehensive temperature range and the relation model, so that the cutting temperature is beyond the comprehensive temperature range to inhibit the generation of the precipitates.

A manufacturing system includes a base and multiple work machine modules that are attachable and detachable to and from the base arranged in the arrangement direction on the base or on the side of the base, in which the plurality of work machine modules include one or more processing work modules that perform machine processing work on a workpiece using a tool, and one or more supplementary work modules that perform supplementary work that is work supplementarily performed to the machine processing work. Since it is possible to easily increase and decrease the number of processing work modules and supplementary work modules or sort the modules, it is possible to easily recombine the modules with respect to modification of the manufacturing process.
