摘 要

隨著社會的發(fā)展和科技的進(jìn)步，傳統(tǒng)的鞋楦生產(chǎn)方式遠(yuǎn)遠(yuǎn)不能適應(yīng)當(dāng)今制鞋業(yè)快速發(fā)展的需要。中國的制鞋業(yè)正面臨巨大的挑戰(zhàn)，傳統(tǒng)的作坊式生產(chǎn)已經(jīng)既不能滿足消費者的要求，也不符合所謂“制鞋大國”的市場需求，因此必須對現(xiàn)行的制鞋工藝進(jìn)行全面的數(shù)字化、自動化改造。
本文重點研究鞋楦的快速測量，以及將測量數(shù)據(jù)通過CAD/CAM系統(tǒng)進(jìn)行曲面建模和鞋楦數(shù)控加工。將CAD/CAM技術(shù)應(yīng)用于鞋楦設(shè)計制造中，將大大改變傳統(tǒng)的鞋楦設(shè)計制造方式、縮短鞋楦生產(chǎn)周期、提高產(chǎn)品質(zhì)量。從鞋楦測量數(shù)據(jù)的采集、處理，刀位點計算、數(shù)字仿真，一直到加工程序的生成，每個環(huán)節(jié)如果采用市場上現(xiàn)有的軟件，成本昂貴且費時長，對操作人員技術(shù)水平要求較高。
所以，論文分析了鞋楦CAD/CAM技術(shù)，采用離散法造型技術(shù)建立鞋楦三維模型,并應(yīng)用數(shù)據(jù)庫理論建立鞋楦數(shù)據(jù)庫，為鞋楦CAD/CAM系統(tǒng)建立完善的體系化環(huán)境。

ABSTRACT

With the development of society and improvement of science and technology,the
traditional mode of making the Shoe-last is not adapt to the requirement of the rapiddevelopment of shoe manufacture industry presently. The shoemaking industry in China is facing a great challenge,traditional workshop-style production neither meet the need of consumer nor meet the need of market as a so-called big shoemaking country,therefore,we must direct the current craftwork to numerial and automotive machining.
The process itself limits shoe-last industry development due to higher cost,longer cycle as well as lower quality.However,the reform to apply CAD/CAM technologies into shoe-last design and manufacturing,will hence change traditional shoemaking greatly,shorten manufacture cycle,and improve quality of lasts.
the paper analyses CAD/CAM technologies in last-making industry,and builds shoe-last 3D model with discrete modeling method.In addition，this paper adopts Database classifying shoe lasts and builds a perfectly systematic environment for shoe-last CAD/CAM.

Keywords:shoe-last, fast measurement,CAD,CAM, database management system
