多边形深孔类零件数控铣床程序及工装设计

摘  要

装备工业的技术水平和现代化程度决定着整个国民经济的水平和现代化程度，数控技术及装备是发展新兴高新技术产业和尖端工业的使用技术和最基本的装备。马克思曾说过这样一句话：“各种经济时代的区别，不在于生产什么，而在于怎样生产，用什么劳动资料生产。”制造技术和装备就是人类生产活动的最基础的生产资料，而数控技术又是当今先进制造技术和装备最核心的技术。当今世界各国制造业广泛采用数控技术，以提高制造能力和水平，提高对动态多变市场的适应能力和竞争能力。此外世界上各个工业比较发达的国家还将数控技术及数控装备列为国家的重要战略物资，不仅采取重大措施来发展自己的数控技术及其产业，而且在“高精尖”数控关键技术和装备方面对我国实行封锁和限制政策。总之，大力发展以数控技术为核心的先进制造技术已成为世界各发达国家加速经济发展、提高综合国力的重要途径。

ABSTRACT

The equipment industry technical level and the modernized degree were deciding the entire national economy level and the modernized degree, the numerical control technology and the equipment are the development emerging high technology and new technology industry and the state-of-art industry use technology and the most basic equipment.Marx had said “each kind of economical time difference, does not lie in produces any, but how lies in produces, with any means of labor production”.The technique of manufacture and the equipment is the humanity produces active the most basic producer goods, but the numerical control technology also is advanced now the technique of manufacture and the equipment most core technology.Now the various countries manufacturing industry widely uses the numerical control technology, sharpens the manufacturing capacity and the level, enhances to the dynamic changeable market adaptiveness and competitive ability. In addition in the world various industries developed country also lists as the national strategic resources the numerical control technology and the numerical control equipment, not only takes the significant measure to develop own numerical control technology and the industry, moreover implements the blockade and the limit policy in “precise and advanced” the numerical control key technologies and the equipment aspect to our country.In brief, develops vigorously take the numerical control technology has become the world each developed country acceleration economy development as the core advanced technique of manufacture, enhances the comprehensive national strength and the national status important way.
