style="text-indent:25px">銑刀的幾何角度:銑刀的種類、形狀雖多，但都可以歸納為圓柱銑刀和面銑刀兩種基本形式，每個刀齒可以看作是一把簡單的車刀，所不同的是銑刀回轉(zhuǎn)、刀齒較多。因此只通過對一個刀齒的分析，就可以了解整個銑刀的幾何角度。以面銑刀為例來分析銑刀的幾何角度。面銑刀的標注角度如圖4-2所示。面銑刀的一個刀齒，相當于一把小車刀，其幾何角度基本與外圓車刀相類似，所不同的是銑刀每齒基面只有一個，即以刀尖和銑刀軸線共同確定的平面為基面。因此面銑刀每個刀齒都有前角、后角、主偏角和刃傾角四個基本角度。（1）前角γο：前面與基面之間的夾角，在正交平面中測量。（2）后角αo：后面與切削平面之間的夾角，在正交平面中測量。（3）主偏角κr：主切削平面與假定工作平面間的夾角，在基面中測量。（4）刃傾角λs：主切削刃與基面之間的夾角。大銑刀銷售公司硬質(zhì)合金鋸片包括合金刀頭的品種、基體的原料、直徑、齒數(shù)、厚度、齒形、視點、孔徑等多個參數(shù)。</p><div

style="text-indent:25px">銑削方式選擇：改進銑削加工的另一種方式是優(yōu)化面銑刀的銑削策略。在對平面銑削進行加工編程時，用戶必須首先考慮刀具切入工件的方式。通常，銑刀都是簡單地直接切入工件(圖 1)。這種切入方式通常會伴隨很大的沖擊噪聲，這是因為當?shù)镀顺銮邢鲿r，銑刀所產(chǎn) 生的切屑較厚所致。由于刀片對工件材料形成很大的沖擊，往往會引起振動，并產(chǎn)生會縮短刀具壽命的拉應(yīng)力。一種更好的進刀方式是采用滾動切入法，即在不降低進給率和切削速度的情況下，銑刀滾動切入工件(圖2)。這意味著銑刀必須順時針旋轉(zhuǎn)，確保其以順銑方式進行加工。這樣形成的切屑由厚到薄，從而可以減小振動和作用于刀具的拉應(yīng)力，并將更多切削熱傳入切屑中。通過改變銑刀每次切入工件的方式，可使刀具壽命延長1－2倍。為了實現(xiàn)這種進刀方式，刀具路徑的編程半徑應(yīng) 采用銑刀直徑的1/2，并增大從刀具到工件的偏置距離。</p><p style="text-indent:25px">成形銑刀：1、鏟齒的基本概念：成形銑刀可分為尖齒和鏟齒兩種.尖齒成形銑刀的銑削和重磨需要專門靠模，制造和刃磨都較困難。鏟齒成形銑刀齒背是在鏟齒車床上鏟削和鏟磨而成，重磨時只磨前刀面，因為前刀面是平面，所以刃磨比較方便，目前成形銑刀主要采用鏟齒齒背結(jié)構(gòu)。鏟齒齒背應(yīng)滿足兩個條件：①重磨后切削刃形狀不變；②獲得所需后角。2、齒背曲線及方程：通過銑刀切削刃上任意點作垂直于銑刀軸線的端剖面，它與齒背表面的交線稱為銑刀的齒背曲線。齒背曲線主要應(yīng)滿足兩個條件：一是銑刀每次重磨后的后角基本不變；另一是制造簡單。能滿足后角不變的曲線只有對數(shù)螺旋線，但難以制造。阿基米德螺旋線能滿足后角基本不變，制造簡單，容易實現(xiàn)。所以在生產(chǎn)上普遍采用阿基米德螺旋線作為成形銑刀齒背曲線。合金銑刀適合于鑄鐵材料的精加工及半精加工，具有良好抗沖擊性及抵抗塑性變形能力。</p><div

style="text-indent:25px">圓周銑的銑削方式:根據(jù)銑削時切削層參數(shù)變化規(guī)律的不同，圓周銑削有逆銑和順銑兩種形式。逆銑銑削時（見圖4-4），銑刀切入工件時的切削速度方向與工件的進給方向相反，這種銑削方式稱為逆銑。逆銑時，刀齒的切削厚度從零逐漸增大。刀齒在開始切入時，由于切削刃鈍圓半徑的影響，刀齒在工作表面上打滑、產(chǎn)生擠壓和摩擦，使這段表面產(chǎn)生嚴重的冷硬層。至滑行到一定程度時（即切削厚度≥切削刃鈍圓半徑），刀齒才能切入工件。下一個刀齒切入時，又在冷硬層上擠壓、滑行，使刀齒容易磨損，同時使工件表面粗糙度值增大。此外，逆銑加工時，當接觸角大于一定數(shù)值時，垂直銑削分力向上，容易使工件的裝夾松動而引起振動。大銑刀銷售公司</p></p><br
