“…This can include further reducing the number, size and weight of manufacturing machines, while increasing their robustness during transportation and operation amidst less controlled environments. There are already some examples of radical reductions in the sizes of machine tools: for example, from more than 20 cubic metres (e.g., 3 × 3 × 2.5 m) to less than two cubic metres [39,40]. Important topics include reducing the size and weight of hybrid additive and subtractive machine tools [41] and reducing uncertainty of machine tool calibration [42].…”

Abstract:Moveable factories can enable leapfrogging of fixed industrial factories, and so make immediate contributions to global goals of more resilient sustainable manufacturing. Moveable factories bring into use diverse technological advances that reduce the number, size, and weight of machines needed to carry out manufacturing operations at points of supply and/or demand. However, fixed industrial factories continue to be the principal focus for development and application of new manufacturing technologies. At the same time, fixed industrial factories continue to be seen by policy makers around the world as the default option for developing prosperity: rather than as an old fashioned production paradigm to be leapfrogged over. In this paper, findings are reported from a case study investigating potential for moveable factories to bring leapfrog manufacturing to an industrial economy. This case study comprised literature review, interviews, and theoretical analyses. Study findings indicate that organisations in an industrial economy will consider moveable factories if fixed factories are not feasible, practical, or viable. By contrast, potential for improved efficiency and flexibility may not be sufficient to motivate a shift away from fixed industrial factories.

“…Erkorkmaz [11] analyzed a precision X-Y working stage along the X,Y and Z axis respectively, while Eisenbies [12] analyzed a CMM machine and Sun [13] analyzed an ultraprecision flycutting machine tool along the same axis direction. Error budget analysis on five-axis machine are done by Cheng [14], Brecher [15] and Treib [16] ,but their analysis are also along the X,Y and Z axis respectively. Ibaraki [17] identified the machine tool errors by machining tests of stepped workpiece, and the map between the machine tool errors and workpiece errors is constructed.…”

Abstract:Customer-oriented design is very important for machine tool manufacturers to win competition in the market. Mechanical parts with complicated sculptured surface are widely utilized in mechanical systems such as automobiles, aircrafts and wind turbines, and they are often machined by five-axis machine tools with high precision requirements. However traditional machine tool design has not accounted for the varied machining errors in producing complex sculptured surface, which leads to inferior performance. To address this challenge, a novel machining error synthesis model is proposed in this paper for accuracy optimization in designing general five-axis machine tools used for making various sculptured surfaces. The new synthesis model bridges between surface machining profile error and the machine tool accuracy, and it is constructed by integrating a generic machine tool volumetric error model and two new surface machining error production models. The synthesis model is then applied as a constraint in machine tool accuracy design optimization. Also a tolerance-cost function is formulated to construct the objective function, and a meta-heuristic algorithm is developed to implement the optimization. All these modeling and optimization methods are validated by one case study.

“…Dorndorf et al [6] studied the optimal allocation of static machine error around the minimum cost, in which considering the probability characteristics of the errors. Brecher et al [7] used the error allocation in the compact design of machine tools for providing the possibility to avoid, separate and compensate the machine errors. Uriarte et al [8] made the overall error allocation for a micro-milling machine, mainly considering the collet angular deformation and tool deflection.…”

Ultra-precision machine tool is the most important physical tool to machining the workpiece with the frequency domain error requirement, in the design process of which the dynamic accuracy design (DAD) is indispensable and the related research is rarely available. In light of above reasons, a DAD method of ultra-precision machine tool is proposed in this paper, which is based on the frequency domain error allocation. The basic procedure and enabling knowledge of the DAD method is introduced. The application case of DAD method in the ultra-precision flycutting machine tool for KDP crystal machining is described to show the procedure detailedly. In this case, the KDP workpiece surface has the requirements in four different spatial frequency bands, and the emphasis for this study is put on the middle-frequency band with the PSD specifications. The results of the application case basically show the feasibility of the proposed DAD method. The DAD method of ultra-precision machine tool can effectively minimize the technical risk and improve the machining reliability of the designed machine tool. This paper will play an important role in the design and manufacture of new ultra-precision machine tool.
