如何確定刀具的轉速、切削速度和切削寬度

　　2.硬質(zhi)合金(jin)刀(dao)(dao)片的端銑刀(dao)(dao)和端銑刀(dao)(dao)主要用于(yu)加工凸出物、溝槽和箱形表面。鐵(tie)道螺(luo)栓(shuan)鋼結構連(lian)接用螺(luo)栓(shuan)性(xing)能等(deng)級分(fen)(fen)3.6、4.6、4.8、5.6、6.8、8.8、9.8、10.9、12.9等(deng)10余(yu)個等(deng)級，其中(zhong)8.8級及以上螺(luo)栓(shuan)材質(zhi)為(wei)低碳合金(jin)鋼或(huo)中(zhong)碳鋼并經熱(re)處理（淬火(huo)、回火(huo)），通稱(cheng)為(wei)高強度螺(luo)栓(shuan)，其余(yu)通稱(cheng)為(wei)普通螺(luo)栓(shuan)。螺(luo)栓(shuan)性(xing)能等(deng)級標號有兩部分(fen)(fen)數字組(zu)成(cheng)，分(fen)(fen)別表示螺(luo)栓(shuan)材料的公稱(cheng)抗(kang)拉(la)強度值(zhi)和屈(qu)強比值(zhi)。

　　3.圓刀(dao)(dao)(dao)，圓刀(dao)(dao)(dao)(也稱為圓鼻刀(dao)(dao)(dao))通常用(yong)來(lai)加(jia)(jia)(jia)工(gong)(gong)(gong)曲面(mian)和(he)(he)(he)可變的(de)(de)倒角輪廓。標(biao)(biao)準件(jian)(jian)指結構(gou)、尺寸、畫法、標(biao)(biao)記(ji)等各個(ge)(ge)方(fang)面(mian)已經(jing)完全標(biao)(biao)準化，并由專業廠生產的(de)(de)常用(yong)的(de)(de)零(部(bu))件(jian)(jian)，如螺紋件(jian)(jian)、鍵(jian)、銷、滾動(dong)軸(zhou)承等等。標(biao)(biao)準化程度高，行業通用(yong)性(xing)強的(de)(de)機械(xie)零部(bu)件(jian)(jian)和(he)(he)(he)元件(jian)(jian)，也被稱為通用(yong)件(jian)(jian)。球刀(dao)(dao)(dao)主要(yao)用(yong)于(yu)(yu)半精(jing)加(jia)(jia)(jia)工(gong)(gong)(gong)和(he)(he)(he)精(jing)加(jia)(jia)(jia)工(gong)(gong)(gong)。帶硬(ying)質合金刀(dao)(dao)(dao)具(ju)(ju)的(de)(de)圓刀(dao)(dao)(dao)主要(yao)用(yong)于(yu)(yu)粗加(jia)(jia)(jia)工(gong)(gong)(gong)。問(wen)：工(gong)(gong)(gong)藝單的(de)(de)目(mu)的(de)(de)是(shi)什(shen)么(me)？加(jia)(jia)(jia)工(gong)(gong)(gong)計(ji)劃表中(zhong)應(ying)包(bao)括哪些(xie)(xie)內(nei)容？(1)加(jia)(jia)(jia)工(gong)(gong)(gong)程序(xu)(xu)是(shi)數(shu)(shu)控加(jia)(jia)(jia)工(gong)(gong)(gong)工(gong)(gong)(gong)藝設計(ji)的(de)(de)內(nei)容之(zhi)一，也是(shi)操(cao)作人(ren)(ren)員(yuan)必須遵守和(he)(he)(he)執行的(de)(de)過程，是(shi)對加(jia)(jia)(jia)工(gong)(gong)(gong)過程的(de)(de)具(ju)(ju)體描述(shu)。目(mu)的(de)(de)是(shi)讓操(cao)作人(ren)(ren)員(yuan)明確程序(xu)(xu)的(de)(de)內(nei)容、夾(jia)緊和(he)(he)(he)定(ding)位方(fang)法，以及在每個(ge)(ge)加(jia)(jia)(jia)工(gong)(gong)(gong)過程中(zhong)選擇刀(dao)(dao)(dao)具(ju)(ju)時(shi)應(ying)注意的(de)(de)問(wen)題等。(Ii)在加(jia)(jia)(jia)工(gong)(gong)(gong)程序(xu)(xu)列(lie)表中(zhong)，應(ying)包(bao)括：圖(tu)紙和(he)(he)(he)程序(xu)(xu)文件(jian)(jian)名稱、工(gong)(gong)(gong)件(jian)(jian)名稱、夾(jia)具(ju)(ju)草圖(tu)、程序(xu)(xu)名稱、每個(ge)(ge)程序(xu)(xu)使(shi)用(yong)的(de)(de)刀(dao)(dao)(dao)具(ju)(ju)的(de)(de)最(zui)大深(shen)度、加(jia)(jia)(jia)工(gong)(gong)(gong)特性(xing)(如粗加(jia)(jia)(jia)工(gong)(gong)(gong)或精(jing)加(jia)(jia)(jia)工(gong)(gong)(gong))、理論加(jia)(jia)(jia)工(gong)(gong)(gong)時(shi)間等。問(wen)：數(shu)(shu)控編(bian)程前應(ying)做哪些(xie)(xie)準備(bei)？答(da)：在確定(ding)加(jia)(jia)(jia)工(gong)(gong)(gong)工(gong)(gong)(gong)藝后，有必要(yao)了解(jie)：1，工(gong)(gong)(gong)件(jian)(jian)夾(jia)緊方(fang)式；
　　2，工件毛胚的(de)尺寸-以確定加(jia)工范圍或是(shi)否需要多次夾(jia)緊(jin)；3、工件的(de)材料-為了選擇用(yong)于加(jia)工的(de)刀具(ju)；
　　4，庫存的刀具有哪些？在加工過程中避免在沒有此刀具的情況下修改程序。地腳螺栓埋深和彎鉤都是為了保證螺栓與基礎的摩擦力，不至于使螺栓發生拔出破壞。地腳螺栓有固定沒有強烈振動和沖擊的設備等作用。如果你必須使用這個工具，你可以提前做好準備。
