摘 要

鞋楦是鞋的母體，是鞋幫樣設(shè)計(jì)、鞋底部件、鞋的成型模具設(shè)計(jì)以及制作鞋和固定鞋造型的依據(jù)。我國大多數(shù)制鞋企業(yè)還是采用手工制作樣楦和簡單的拷模加工方式，成本高、周期長、質(zhì)量差。數(shù)控加工中心采用四軸加工可較快地直接制取母鞋楦。鞋楦刀位點(diǎn)計(jì)算、數(shù)字仿真系統(tǒng)的開發(fā)是鞋楦數(shù)控加工的關(guān)鍵步驟，將影響著鞋楦數(shù)控加工的加工質(zhì)量、加工效率和加工精度。本課題研究鞋楦數(shù)控刀位點(diǎn)計(jì)算及其仿真系統(tǒng)的開發(fā)，采用軟件系統(tǒng)對測量后的處理數(shù)據(jù)進(jìn)行處理得出鞋楦刀位點(diǎn)數(shù)據(jù)，然后根據(jù)刀位點(diǎn)數(shù)據(jù)通過仿真軟件對鞋楦表面進(jìn)行CAM仿真，大大節(jié)約了加工費(fèi)用，也大大降低了操作人員技術(shù)水平的要求。
本文首先概述了國內(nèi)外鞋楦設(shè)計(jì)和制造的現(xiàn)狀。隨后，論文采用離散法造型技術(shù)，根據(jù)鞋楦測量后的處理數(shù)據(jù)構(gòu)建出鞋楦三維模型。論文對鞋楦數(shù)控加工原理進(jìn)行了深入分析，提出了三軸聯(lián)動(dòng)螺旋進(jìn)給加工方法。論文接著闡述了鞋楦刀位點(diǎn)算法中的最小距離法，通過C++ Builder 6.0工具軟件開發(fā)出了鞋楦刀位點(diǎn)算法軟件，得出刀位點(diǎn)數(shù)據(jù)，提高了算法效率。
本文最后介紹了鞋楦數(shù)字仿真技術(shù)并對所獲得的刀位點(diǎn)進(jìn)行了數(shù)字仿真，結(jié)果表明刀位點(diǎn)算法正確，刻楦精度和質(zhì)量也得到了保證，然后通過C++ Builder 6.0工具軟件開發(fā)出了鞋楦仿真系統(tǒng)，通過鞋楦刀位點(diǎn)數(shù)據(jù)得出鞋楦表面仿真數(shù)據(jù)。

ABSTRACT

Lasts are the shoes parent substance, and they are the basis of the uppers of shoes type design, the shoe sole parts, the shoes takes shape the mold design as well as the manufacture shoes and the fixed shoes model. Our country mostly notational shoes enterprises use the manual system and simple beat-processing to produce the shoe last, as the result, the cost is high, the cycle is long, and the quality is poor. NC 4-axis machining center used to be faster made directly from the mother lasts. The lasts NC-point calculation, and the development of last digital simulation system are always essential steps of the numerical control processing to shoe last, are always affecting the numerical control processing quality of last, the processing efficiency and the processing precision. The study of the subject that development of calculation and simulation system for lasts NC-point uses the software system to carry on processing to the survey data to obtain the lasts NC-point, then carries on the CAM simulation according to the lasts NC-point through simulation software to the surface of last, greatly saved the processing charge, also greatly reduced the operator technical level request.
This article first outlines the domestic and foreign last designs and the manufacture present situation. Afterwards, the paper uses the separate method model technology and constructs lasts three-dimensional model according to the last survey data. The paper has carried on the thorough analysis to the numerical control processing principle of last, proposes the three axle linkage spiral precession and gives the processing method. Then thesis expounds lasts knife-point algorithm for the smallest distance, through C + + Builder 6.0 software development tools lasts a knife-point algorithm software, Lasts through the surface measured data knife-point data and increase the efficiency of the algorithm.
This article finally introduces the shoe last digital simulation technology and to the lasts NC-point which obtains has carried on the digital simulation, The results show knife-point algorithm is correct, last carving precision and quality has been guaranteed, then finishes the shoe last simulation system through C++ Builder 6.0 tools software, obtained the last superficial simulation data through the lasts NC-point data.
Key words：shoe last, numerical control processing, knife position spot algorithm, simulation system
