This article offers a critical overview of clay sculpture and terracotta production in ancient Khotan,the Buddhist kingdom located in the southern Tarim Basin,with particular attention to their archaeological,historical,and artistic contexts.It examines the distinctive features of Khotanese sculptural traditions while reassessing long-standing assumptions concerning their chronology and cultural affiliations.After outlining the geographical,historical,and religious background of Khotan,the study discusses the complexities of the archaeological record,shaped by early twentieth-century explorations,undocumented acquisitions from the antiquarian market,and the fragmentary nature of surviving evidence.Special attention is devoted to Buddhist clay sculpture,its architectural setting,iconographic programmes,ritual functions,and technical characteristics.A substantial section is dedicated to the Rawak site,traditionally regarded as one of the earliest examples of Khotanese Buddhist art.Through a reassessment of its architecture,sculptural style,and broader artistic connections,the article argues that Rawak and its clay sculptures should be dated not to the 3rd-5th centuries CE,as commonly assumed,but rather to the 6th-7th centuries.The article also re-examines the corpus of Khotanese terracottas,including decorated vessels,figurines,and masks,traditionally assigned to the Kushan period.Iconographic motifs,musical instruments,costume details,and decorative patterns instead suggest a later chronology,consistent with the cultural milieu of the 6th-7th centuries CE and with wider exchanges along the Silk Road.The study concludes that the archaeological record of Khotan reflects a far more complex and dynamic artistic landscape than previously recognised.By proposing a revised chronology for major sculptural traditions and emphasising the need for renewed archaeological investigation,the article contributes to a broader understanding of Buddhist art and cultural interactions across Central Asia. 展开更多

The problem of finished surface being not first-order continuous commonly exists in machining sculptured surfaces with a torus cutter and some other types of cutters. To solve this problem, a dual drive curve tool path planning method is proposed in this article. First, the maximum machining strip width of a whole tool path can be obtained through optimizing each tool position with multi-point machining （MPM） method. Second, two drive curves are then determined according to the obtained maximum machining strip width. Finally, the tool is positioned once more along the dual drive curve under the condition of tool path smoothness. A computer simulation and cutting experiments are carried out to testify the performance of the new method. The machined surface is measured with a coordinate measuring machine （CMM） to examine the machining quality. The results obtained show that this method can effectively eliminate sharp scallops between adjacent tool paths, keep tool paths smooth, and improve the surface machining quality as well as machining efficiency. 展开更多

The current research of the 5-axis tool positioning algorithm mainly focuses on searching the local optimal tool position without gouging and interference at a cutter contact(CC)point,while not considering the smoothness and continuity of a whole tool path.When the surface curvature varies significantly,a local abrupt change of tool paths will happen.The abrupt change has a great influence on surface machining quality.In order to keep generated tool paths smooth and continuous,a five-axis tool positioning algorithm based on smooth tool paths is presented.Firstly,the inclination angle,the tilt angle and offset distance of the tool at a CC point are used as design variables,and the machining strip width is used as an objective function,an optimization model of a local tool positioning algorithm is thus established.Then,a vector equation of tool path is derived by using the above optimization model.By analyzing the equation,the main factors affecting the tool path quality are obtained.Finally,a new tool position optimization model is established,and the detailed process of tool position optimization is also given.An experiment is conducted to machine an aircraft turbine blade by using the proposed algorithm on a 5-axis blade grinding machine,and the machined blade surface is measured with a coordinate measuring machine(CMM).Experimental and measured results show that the proposed algorithm can ensure tool paths are smooth and continuous,improve the tool path quality,avoid the local abrupt change of tool paths,and enhance machining quality and machining efficiency of sculptured surfaces. 展开更多

A direct interpolation algorithm for spatial curves on a surface is proposed for pen-cutting of sculptured surfaces. The algorithm can carry out the direct interpolation for projective curves lying on the sculptured surface. It is based on the geometric and kinetic relationships between drive curves and cutter-contact （C-C） curves. It evaluates the parameter of drive curves corresponding to interpolation points by the Taylor formula. Then it gains coordinates of interpolation points indirectly by inverse calculation. Finally, it generates the motion commands for machine tool controller. This method extends the locus-controlled function in the computer numerical control （CNC） system effectively and improves the efficiency for the numerical control （NC） machining of sculptured surfaces. The simulation shows that the proposed algorithm is feasible and practical. This algorithm can also be applied to the machining of the whole surface. 展开更多

On-machine inspection has a significant impact on improving high-precision and efficient machining of sculptured surfaces. Due to the lack of machining information and the inability to adapt the parameters to the dynamic cutting conditions, theoretical modeling of profile inspection usually leads to insufficient adaptation, which causes inaccuracy problems. To address the above issues, a novel coupled model for profile inspection is proposed by combining the theoretical model and the data-driven model. The key process is to first realize local feature extraction based on the acquired vibration signals. The hybrid sampling model, which fuses geometric feature terms and vibration feature terms, is modeled by the lever principle. Then, the weight of each feature term is adaptively assigned by a multi-objective multi-verse optimizer.Finally, an inspection error compensation model based on the attention mechanism considering different probe postures is proposed to reduce the impact of pre-travel and radius errors on inspection accuracy. The anisotropy of the probe system error and its influence mechanism on the inspection accuracy are analyzed quantitatively and qualitatively. Compared with the previous models, the proposed hybrid profile inspection model can significantly improve the accuracy and efficiency of on-machine sampling. The proposed compensation model is able to correct the inspection errors with better accuracy. Simulations and experiments demonstrate the feasibility and validity of the proposed methods. The proposed model and corresponding new findings contribute to high-precision and efficient on-machine inspection, and help to understand the coupling mechanism of inspection errors. 展开更多

The sculptured surface is approximated by a regular mesh ofquadrangular facets. A set of equidistant horizontal planes are assigned to intersect the blank ofmachined part and surface model , resulting in a series of contours, which demarcate the feasiblecutting regions of each layer of material removal. The desired cutter path is computed through NCprogramming and any gouging between the cutter and the part being machined is detected and correctedautomatically. The proposed algorithm successfully solves the problem of layered milling forsculptured surface with nested islands. 展开更多

We have theoretically simulated the optical properties of perturbed chiral STF （sculptured thin film） with and without defect. It was revealed that such STFs could act as band-reject filters with tunable Bragg regime of free space wavelengths and different bandwidth through changing the vapor incident angle during glancing angle deposition process. These Bragg filters are narrowing due to the change of vapor incident angle for circularly polarized light. Interestingly, as the vapor incident angle increased, the band-rejected filter exhibited to decrease the bandwidth and shifted in the Bragg regime, indicating that such STF nanostructures have high potential for behaving as unique polarization insensitive Bragg mirror. 展开更多

Human beings rely on natural instinct to feel the world from the beginning of life, the experience in the spatial place reveals the essential point contacting man and environment, also sublimates the relationship between man and environment. To deepen the understanding of the experience in the spatial place, we shift the origin of environmental landscape design from "design environment" to "design experience". The essence of experience is to arouse perception, such as senses, emotions, spirits, thinking, action to participate, among which "form, space, quality" as the carrier of landscape sculpture's place spirit and experience co-form a complete spatial place imagery of landscape sculpture. Place experience makes people able to experience a more detailed and richer world, these construction activities bring innovation consciousness with inner vitality, and detail the means of man observing the world while seeking a pluralistic world. 展开更多

To enhance the ability of current modeling system, an uniformed representation is designed to represent wire frame, solid, surface models. We present an algorithm for Boolean operation between the models under this representation. Accuracy, efficiency and robustness are the main consideration. The geometric information is represented with trimmed parametric patches and trimmed parametric splines. The topological information is represented with an extended half edge data structure. In the process of intersection calculation, hierarchy intersection method is applied for unified classification. Tracing the intersection curve to overcome degenerate cases that occur frequently in practice. The algorithm has been implemented as the modeling kernel of a feature based modeling system named GS CAD98, which was developed on Windows/NT platform. 展开更多
