摘 要

鞋楦是制鞋的基础和重要模具。我国是当今世界的制鞋大国，但制楦技术的落后严重制约了我国制鞋业的发展和技术的进步。随着人们生活水平的提高，追求个性化已经成为一种时尚，一种生活需求，穿着时尚且个性化的鞋已成为人们生活的一项重要内容。所以，开发数控刻楦机就是为了适应品种多、周期短的现代鞋楦生产的需要。
本文首先阐述了鞋楦制造的国内外现状，以了解国外的先进技术和发展趋势，以及我国在这一领域存在的差距。接着又阐述了数控刻楦机的发展现状，为研制数控刻楦机的机械系统作出指引。数控刻楦机综合应用了计算机技术、自动控制技术、精密测量技术和机床结构设计技术等方面的最新成就的高效自动化精密机床；它是鞋楦CAD/CAM系统的最终输出设备，是鞋楦CAD/CAM系统中最关键的一环。
1. 分析了国内外鞋楦设计制造的现状和存在的问题，在此基础上提出了解决我国制鞋业技术设备落后问题的关键，抓紧研制有我们自主知识产权的数控刻楦机 。
2. 从实现鞋楦数控加工的关键技术出发，论述了数控机床的构成和工作原理 。
3. 详细设计了刀具系统、主轴系统、装夹系统、数控刻楦机整体结构的研究。

ABSTRACT

Last is the foundation and an important shoe mold. China is the world's shoe-making power, but the backward technology Last system has seriously hampered the development of China's shoe-making industry and technological progress. With the improvement of people's living standards, the pursuit of personality has become a trend, the demand for a living, wearing a personalized fashion and the shoes have become an important part of life. Therefore, the development of CNC machine Last Carving is in order to meet more varieties, short cycle of modern shoe last production needs.
This paper described the domestic and international current situation made of the shoe Last at first, in order to find out about foreign advanced technology and development trend, and the disparity that our country exists in this field. Then expounded numerical control carves the current situation of the development of the shoe last machine, has guided for the mechanical system that develops numerical control and carves the shoe last machine. NC Last Carves a comprehensive application of computer technology, automatic control technology, precision measurement technology and machine tools, such as structural design of the latest technical achievements of the highly efficient automated precision machine tools； It is the final output apparatus of the shoe Last CAD/CAM system, is the most key ring in shoe Last CAD/CAM system.
1. Have analyzed that designs current situation and existing problem made with domestic and international shoe Last, have proposed solving the key to the backward problem of technical equipment of shoes manufacturing industry of our country on this basis, develop the numerical control with our independent intellectual property right and carve the shoe last machine as soon as possible.
2. Have described the composition of the numerical control lathe and operation principle from realizing the key technology of numerical control processing of shoe Last sets out.
3. Have narrated the cutter system, main shaft system, put and inserted the system, numerical control to carve the research of the whole structure of the shoe last machine in design.
