本书是在2002年出版的中等职业学校电子信息类教材《机电专业英语》的基础上，根据中等职业教育专业的发展现状及原教材使用过程中的反馈信息而进行更新和修订而成的。本书强化了对机电专业英语词汇的掌握，删除了原书中基础模块和翻译技巧方面的内容，增加了英文简历撰写方面的内容。

全书用英语教学的方式介绍了机械、模具、电子、自动化和数控等几个方面的知识。

本书是一本宽口径的专业英语教材，全书按模块式结构编写，有机械、模具、电子、自动化和数控五个模块，便于不同专业的学生选用，也方便教师在不同的模块中选择课文组织教学以适应教学改革的需要。全书各课所选内容篇幅适中、图文并茂，有较强的实用性。

本书可作为中等职业学校机电类及相关专业的教材，高职高专同类专业亦可选用，也可供有关工程技术人员参考使用。

本书配有电子教学参考资料包，以方便教师教学和学生自主学习。
