Application of Chinese Ethnic Minority Themes in Contemporary Figurative Sculpture Creation

In the field of contemporary sculpture creation,the rich culture and historical depth of Chinese ethnic minorities have attracted the widespread attention of artists.These creations not only emphasize external features such as ethnic costumes,totems,or life scenes but also touch deep spiritual contents including historical stories,religious beliefs,and living habits of ethnic minorities.This paper discusses the integration process of Chinese ethnic minority themes in figurative sculpture creation and the inheritance of the profound spirit of ethnic groups in this process.At the same time,this paper also places the diversified expression and innovative practice of these themes in sculpture art in the context of the new era for investigation and explores the far-reaching influence of its development on promoting cultural inheritance and artistic innovation.

Direct interpolation algorithm for pen-cutting of sculptured surfaces

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.

Tool Positioning Algorithm Based on Smooth Tool Paths for 5-axis Machining of Sculptured Surfaces

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.

NON-CONTACT MEASUREMENT OF SCULPTURED SURFACE OF ROTATION

A method for measuring the sculptured surface of rotation by using coordinatemeasuring machine (CMM) and rotary table is proposed. The measurement is realized during thecontinuous rotation of the workpiece mounted on the rotary table while the probe moves along thegeneratrix of the surface step by step. This method possesses lots of advantages such as simplicityof probe motion, high reliability and efficiency. Some key techniques including calibration of theeffective radius of the probing system, determination of the position of axis of rotation,auto-centering of the workpiece, data processing algorithm, are discussed. Approaches fordetermining the coordinates on measured surface, establishing workpiece coordinate system andsurface fitting are presented in detail. The method can be used with contact or non-contact probes.Some fragile ceramic and plaster parts are measured by using the system consisting of a CMM, rotarytable, motorized head and non-contact laser triangulation probe. The measuring uncertainty is about0.02 mm which meets the general requirement in most cases.

NC Rough Machining of Sculptured Surface Based on Measured Data

A new method for generating tool paths for rough machining of sculpturedsurface is presented in this paper. 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.

Robust Boolean Operation for Sculptured Models

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.

Band-Reject Filters for Bragg Mirror Using Perturbed Chiral Sculptured Thin Films

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.

After detecting and eliminating the tool interference, the interference-free tool path is generated. The effectiveness of the developed algorithm is demonstrated through simulation and actual cutting tests.

佩特的审美批评原理

佩特倡导“为艺术而艺术”,主要着眼于艺术鉴赏而非艺术创作,故此一再强调艺术对人生质量的催化与优化作用,力求实现艺术化人生的终极目的。为此,他贬斥抽象笼统的艺术评论公式,推举具体化的审美批评原理。持守这一原理,他以文艺复兴与古希腊艺术为例,颇有成效地呈现出艺术解析和审美鉴赏的独特路径。另外,基于多年古典研究的个人体悟,佩特试图从柏拉图美学思想中汲取“为艺术而艺术”的理论根源。这其中的合理性到底有多少,需要认真比照和反思。
