[4A] 這張齒輪圖紙的技術(shù)說明,，你能看出哪里需要完善,？

十年一夢

大家討論一下有什么需要完善之處,。

機械神話

希望看到這張圖,，機械圖紙是圖文并存的，不可分離,。

這是你自己出圖紙給鬼佬加工的,？

5 C$ M- @4 U1 {- X" t這里的軸可能用axis比較合適,，因為這根軸線不是實際存在的東西,，同軸度本身就是個跳動值所以不用TIR。更應(yīng)該直接標在圖上,。

4. PROTECT THESE SURFACES FROM SCRATCHES AND TOOL MARKS.
保護刮傷正常,，保護刀痕不正常。刀痕都是加工出來的,，不存在保護就會消失,。

13.AFTER FINAL GRINDING, BLEND ALL SHARP EDGES, REMOVE ALL BURRS.
我通常會用Break all burr. Sharp edge本身在機械零件里不是缺陷,，該有的地方是你設(shè)計成它有,。要是日用品就不能存在sharp edge。

老兄的東西每次看都有新發(fā)現(xiàn),。但是如果是一個齒輪的note,，好像該有的東西全部沒有：

樓主你這應(yīng)該是單個零件的技術(shù)要求吧,？我覺得第三條動平衡應(yīng)該去掉,，單個零件的在這沒什么用；第五條磨削余量沒必要寫在這個里面吧,，畢竟是工藝要求,；另外，你要求表面刀紋看不出,，那就直接定個粗糙度Ra1.6以下,，這個可去參考粗糙度標準樣塊；第十條未注同心度0.254你有和第三條校核沒,？單位是英制還是公制,？有必要到小數(shù)點后三位？還有最后那條不太清楚你要干什么,。
