Sculptured/curved surfaces, today, are widely used in several industries, for instance, automotive, aerospace, bio-medical components, precision machine design and die-mould industries. Recent improvements in CAM software have allowed the manufacturing of complex curved geometries. The ball-end/nose milling is a flexible process that is capable of milling both convex and concave part surfaces with rough, semi-rough and finish processes. The sculptured surface milling is mostly realized by the repeated motion of a rotating cutter along predefined trajectories. Manufacturing engineers can choose the cutter paths generation approach from a set of typical paths (zig, zig-zag, concentric, radial tool paths, etc.) in commercial CAM software. In addition, these strategies cannot be optimized for all complex surfaces to be milled. A substantial number of studies have examined this subject, and many path-generation approaches have been developed, as shown in Fig. 1 [1] and [2].The strategies can be sorted into three basic categories: offset, single direction, and raster. In offset milling, the cutter starts at the periphery of the face and then proceeds spirally inwards. In a raster milling strategy (zig, zig-zag, or sweep) the cutting tool moves back and forth across the milled workpiece [3]. In spiral milling, the cutter returns to the start-point of each cycle and then cuts outwards to the next outer cycle. When using a spiral strategy, the cutting time is hugely decreased. The selection of the proper milling strategy in the process of milling will decrease cutting time, improve the surface quality of the finished part and tool life and reduce machining costs and cutting forces.

“…In the case when some errors cannot be entered in the controller directly, an off-line error compensation technique is required. This technique should compensate the manipulator errors via modification of the target trajectory that becomes slightly different from the desired one [46].…”

Geometric calibration of industrial robots using enhanced partial pose measurements and design of experiments. Robotics and Computer-Integrated Manufacturing, Elsevier, 2015, 35, pp.151-168 The paper deals with geometric calibration of industrial robots and focuses on reduction of the mea-surement noise impact by means of proper selection of the manipulator configurations in calibration experiments. Particular attention is paid to the enhancement of measurement and optimization techniques employed in geometric parameter identification. The developed method implements a complete and irreducible geometric model for serial manipulator, which takes into account different sources of errors (link lengths, joint offsets, etc). In contrast to other works, a new industry-oriented performance measure is proposed for optimal measurement configuration selection that improves the existing techniques via using the direct measurement data only. This new approach is aimed at finding the ca-libration configurations that ensure the best robot positioning accuracy after geometric error compen-sation. Experimental study of heavy industrial robot KUKA KR-270 illustrates the benefits of the devel-oped pose strategy technique and the corresponding accuracy improvement.

In order to solve the problem of low measurement efficiency of volumetric errors and predict the volumetric errors of CNC machine tools online, a new volumetric error modeling method based on information fusion technology is proposed in this paper, which was used for the volumetric error prediction of a two turntable five-axis machine tool. In order to fulfill the volumetric error modeling, the displacement variables, temperature variables, and cutting force variables were determined firstly, then the determined variables and the volumetric errors were measured and analyzed, and a volumetric error model was presented based on the determined variables. In order to optimize the parameters of the presented model, grey correlation analysis method is used for the second time prediction of the volumetric errors. Finally, the performance of the model was tested by an experiment. The result shows that the approximation ability of the model is very well, and the residual error is smaller than 2 μm. Comparing with conditional modeling methods, this method can be used in different types of machine tools with different operating conditions by regulating the weight matrix, and the robustness of the fusion model is improved.
