“…For thin-walled part, such as the cantilever-type parts and the plate-type parts, lots of researches focus on the simulationbased numerical prediction of force-induced local elastic deformation [2,4,18,19] and the stress-induced overall deformation [3,16,22], respectively. Using the deformation simulation results, the toolpaths and the cutter localizations can be compensated point-by-point.…”

There is a kind of large thin-walled parts in aerospace industry, the machining target surface of which is tightly associated with another specific surface (named correlative surface). And it is always the primary machining objective. However, the preformed correlative surface is significantly different from its original design model due to large profile and thickness errors. Thus, part-referenced machining is necessary to ensure the correlative constraint accuracy. In this article, an integration strategy of OMM and NC machining for the large thin-walled parts with surface correlative constraint is systematically developed. Generally, the integration process consists of correlative constraint analysis, on-machine measurement, machining target surface redesign, and NC machining. Firstly, an isoplanar-based on-machine scanning method is presented for large surface profile information extraction. Then, a unified target surface redesign model is established according to surfaces accompanying relation analysis. Further, to compensate stress-induced monotonic structural deformation, a partitioned measuring and machining approach has been employed. Finally, the liquid rocket engine nozzle as a typical part was employed to verify the validation of the proposed strategy. Coolant channel machining experiments were conducted on a special dual-spindle machine tools. For a nozzle with machining area about 8 m 2 , the correlative accuracy could be controlled in the range of ±0.1 mm. It has been proved that incorporating dimensional metrology feedback to machining process could consistently improve machining quality and efficiency of large thin-walled parts.

“…The magnitude of load induced errors depends upon the object loading behaviour, object weight, machining forces, and unbalanced unforeseen forces in machine elements which affect the stiffness of the structural loop. Though it has been reported that in finish-machining the cutting force is small and the resultant deflection could be neglected [3], studies on load induced error compensation have been found to improve machine accuracy [22][23][24][25].…”

Load induced errors aroused by internal masses of machine tool components and external cutting forces are a main contributor that influences machining accuracy. A mathematical model for load induced errors identification of large-span crossbeam in heavy-duty machine tool was proposed. According to the identified load induced errors, a method for optimisation of the guideway camber curve on crossbeam by particle swarm optimisation was proposed. Geometric errors of y-axis along cambered crossbeam and noncambered crossbeam were calibrated, and multibody system theory was also introduced to predict theoretically the machining accuracy of machine tool with two kinds of crossbeam. The comparisons between two kinds of crossbeam show that after cambering, the geometric errors are decreased and can meet the requirements of ISO standard, and the machining accuracy is enhanced remarkably too. In addition, the indirect dynamic straightness error of z-direction along cambered crossbeam was measured by displacement sensors, and the response results show that even though at the start-stop moment, the straightness error is also within the reasonable range of ISO standard.
