北京理工大学珠海学院 2020 届本科生毕业设计切削刀具角度模型示教系统设计与制作-主副偏角与后角机构设计切削刀具角度模型示教系统设计与制作-主副偏角与后角机构设计北京理工大学珠海学院 2020 届本科生毕业设计摘 要切削刀具角度模具示教系统（Teaching system of cutting tool angle model）是一种能够直观地、动态的展示刀具切削角度的示教系统。它是一个以车刀为原型能够在课堂上进行辅助教学的较小型的教学模型，能够直观的展示出切削刀具的虚拟平面：基面、正交平面；将虚拟的、抽象的转换为实体，通过单片机、电机和传动机构将主副偏角、前角和后角等角度的变化在基面、正交平面和切削平面上直观的展现；并且直接的体现出刀具角度变化的度数。关键词：切削刀具角度，角度变化 ，直观的展示，模具示教系统北京理工大学珠海学院 2020 届本科生毕业设计Design and manufacture of cutting tool angle model teaching system-design of main and auxiliary declination and back angle mechanismAbstractTeaching system of cutting tool angle model (Teaching system of cutting tool angle model) is a teaching system that can intuitively and dynamically display the cutting angle of the tool. It is a small teaching model that can use the turning tool as a prototype to provide auxiliary teaching in the classroom. It can intuitively display the virtual plane of the cutting tool: the base plane and the orthogonal plane; convert the virtual and abstract into a solid, Through the single-chip microcomputer, the motor and the transmission mechanism, the angle changes of the main and auxiliary declination angle, rake angle and back angle are visually displayed on the base plane, the orthogonal plane and the cutting plane; and the degree of change of the tool angle is directly reflected.Keywords: Cutting tool angle, angle change, visual display, mold teaching system 北京理工大学珠海学院 2020 届本科生毕业设计目录1 前言................................................................
