前言
中巴、中非友谊源远流长,加大教育国际援助力度,具有针对性地开展紧缺教学资源建设,不仅可以提高多层次、宽领域的国际教育水平,而且有助于增进国际友谊,为一带一路合作绘制工笔画。
数控技术作为先进制造领域的核心技术,是教育援外机械专业本科生和研究生的必修知识。然而,现有数控技术课程双语教学资源不足,现有教材出版日期较早,缺乏先进数控技术及应用等方面的知识。为填补本领域空白,有针对性地为发展中国家培养数控技术人才,特编写本教材。
本教材分为5章,主要涵盖数控机床发展史、数控系统工作原理、伺服系统结构及工作原理、机械结构、智能制造等内容。本教材按照数控机床的主要工作流程编写,详略得当; 重运用、强实践,将抽象的原理与实际应用有机结合; 追踪先进技术的发展,涵盖智能制造技术最新成果。关键词语采用双语说明方式。可以作为中巴、中非合作办学的机械工程专业留学生专业教材、高年级本科生双语教材,也可以供数控技术人员自学参考。教材包含实验指导书,强化学生实践创新能力的拓展。
本教材第1章由天津职业技术师范大学赵巍、旁遮普天津技术大学MUHAMMAD ALI MANSOOR编写; 第2章由天津职业技术师范大学赵楠、旁遮普天津技术大学MUHAMMAD KASHIF IJAZ编写; 第3章由天津大学董靖川编写; 第4章由天津职业技术师范大学赵巍、张翔宇,旁遮普天津技术大学RAMEEZ UL HASSAN编写; 第5章由天津职业技术师范大学刘鹏鑫、赵楠,湖州职业技术学院王英杰编写。全书由付晓燕校稿,旁遮普天津技术大学Dr.Syed Asim Ali Shah、天津职业技术师范大学满佳老师、北京格瑞纳电子产品有限公司赵伟工程师以及研究生刘梦莹、王丽娜、何苗等也参与了本教材的审核、编辑等工作。
在教材的编写过程中参考了一些数控技术相关的教材和资料,特向其作者表示真诚的感谢。鉴于作者水平有限,书中不可避免地存在缺点、不足,敬请各位读者批评指正。
