style="text-indent:25px">車刀的主要幾何角度及選擇：1、后角(α0)選擇的原則。首先考慮加工性質(zhì)。精加工時(shí)，后角取大值，粗加工時(shí)，后角取小值。其次考慮加工材料的硬度，加工材料硬度高，主后角取小值，以增強(qiáng)刀頭的堅(jiān)固性；反之，后角應(yīng)取小值。后角不能為零度或負(fù)值，一般在6°～12°之間選取。2、主偏角(Kr)的選用原則。首先考慮車床、夾具和刀具組成的車削工藝系統(tǒng)的剛性，如系統(tǒng)剛性好，主偏角應(yīng)取小值，這樣有利于提高車刀使用壽命、改善散熱條件及表面粗造度。其次要考慮加工工件的幾何形狀，當(dāng)加工臺(tái)階時(shí)，主偏角應(yīng)取90°，加工中間切入的工件，主偏角一般取60°。主偏角一般在30°～90°之間，較常用的是45°、75°、90°。杭州木工車刀定做棱體成形車刀的刀頭和刀桿分開制作,較大增加了沿前刀面的重磨次數(shù),刀體剛性好。</p><div

style="text-indent:25px">車刀的主要幾何角度及選擇：1）前角(γ0)選擇的原則。前角的大小主要解決刀頭的堅(jiān)固性與鋒利性的矛盾。因此首先要根據(jù)加工材料的硬度來選擇前角。加工材料的硬度高，前角取小值，反之取大值。其次要根據(jù)加工性質(zhì)來考慮前角的大小，粗加工時(shí)前角要取小值，精加工時(shí)前角應(yīng)取大值。前角一般在-5°～25°之間選取。通常，制作車刀時(shí)并沒有預(yù)先制出前角（γ0），而是靠在車刀上刃磨出排屑槽來獲得前角的。排屑槽也叫斷屑槽，它的作用大了去了折斷切屑，不產(chǎn)生纏繞；控制切屑的流出方向，保持已加工表面的精度；降低切削抗力，延長刀具壽命。</p><p
