43届世赛数控铣项目模块三加工难点剖析

Analysis of the Difficulties for the 43rd WorldSkills Competition CNC-Milling Project Module Three

选取2015年第43届世赛数控铣项目模块三作为研究对象,通过细致研究和详细解读模块三图纸,对影响该零件加工的毛坯材料、尺寸精度和位置精度、表面粗糙度、刀具要求、加工方式和检测手段共9个难点方面进行剖析和探讨,为后续工艺规划、加工方案设计及CAD建模和CAM编程加工提供指导并奠定了基础,同时为读者研究世赛数控铣项目提供了借鉴和参考。

This paper selects module 3 of the 43rd WorldSkills Competition CNC-Milling project in 2015 as the research object.Through detailed research and detailed interpretation of module 3 drawings,the blank material,dimensional accuracy and position accuracy,surface roughness,tool The requirements,processing methods and testing methods are analyzed and discussed in nine difficult aspects,which provide guidance and lay the foundation for subsequent process planning,processing plan design,CAD modeling and CAM programming processing.At the same time,it is provided reference and reference for readers to study WorldSkills Competition CNC-Milling project.
