[4A] 这张齿轮图纸的技术说明，你能看出哪里需要完善？

十年一梦

大家讨论一下有什么需要完善之处。

希望看到这张图，机械图纸是图文并存的，不可分离。

这是你自己出图纸给鬼佬加工的？

13.AFTER FINAL GRINDING, BLEND ALL SHARP EDGES, REMOVE ALL BURRS.
我通常会用Break all burr. Sharp edge本身在机械零件里不是缺陷，该有的地方是你设计成它有。要是日用品就不能存在sharp edge。

老兄的东西每次看都有新发现。但是如果是一个齿轮的note，好像该有的东西全部没有：

没有图纸怎么分析啊？楼上有图纸了？

楼主你这应该是单个零件的技术要求吧？我觉得第三条动平衡应该去掉，单个零件的在这没什么用；第五条磨削余量没必要写在这个里面吧，毕竟是工艺要求；另外，你要求表面刀纹看不出，那就直接定个粗糙度Ra1.6以下，这个可去参考粗糙度标准样块；第十条未注同心度0.254你有和第三条校核没？单位是英制还是公制？有必要到小数点后三位？还有最后那条不太清楚你要干什么。
