6°～10°。主偏角κr根據(jù)工藝系統(tǒng)的剛性條件而定,一般取30°～75°,剛性差時(shí)取較大的值，在車階梯軸時(shí)，由于切削方式的需要取大于或等于90°。刀尖圓弧半徑rε和副偏角κr'一般按加工表面粗糙度的要求而選取。刃傾角γS則根據(jù)所要求的排屑方向和刀刃強(qiáng)度確定。車刀前面的型式主要根據(jù)工件材料和刀具材料的性質(zhì)而定?？梢院?jiǎn)單的是平面型，正前角的平面型適用于高速鋼車刀和精加工用的硬質(zhì)合金車刀。</p><p style="text-indent:25px">焊接內(nèi)孔車刀刀具的選擇，主要的問題是刀桿的剛性，刀桿的強(qiáng)度，應(yīng)力，扭轉(zhuǎn)應(yīng)力，剪切應(yīng)力等都考慮。在切削過程中產(chǎn)生的切削力大小相等，方向相反地作用在刀具、工件、夾具和機(jī)床上。（1）主切削力Fz垂直于基面，與切削速度方向一致，所以又稱切向力。在切削加工中，主切削力所消耗的功可以多，所以它是計(jì)算機(jī)床功率、刀桿和刀片強(qiáng)度以及夾具設(shè)計(jì)、選擇切削用量等的主要依據(jù)。（2）徑向力Fy在基面內(nèi)，并與進(jìn)給方向相垂直，也叫背向力。在車削外圓時(shí)，徑向力使工件在水平面內(nèi)彎曲。它會(huì)影響工件的形狀精度，而且容易引起振動(dòng)。（3）軸向力Fx在基面內(nèi)，它與進(jìn)給方向相平行，也叫進(jìn)給力。軸向力是校核機(jī)床進(jìn)給機(jī)構(gòu)強(qiáng)度的主要依據(jù)。若刀具未加緊，會(huì)因軸向力大而引起偏轉(zhuǎn)；若工件未加緊，會(huì)因軸向力大而將工件向卡盤方向推入。車刀前面的型式主要根據(jù)工件材料和刀具材料的性質(zhì)而定。</p><div

style="text-indent:25px">如何選擇內(nèi)孔車刀，方法如下：1、刀柄截面形狀的選用。優(yōu)先選用圓柄車刀。由于圓柄車刀的刀尖高度是刀柄高度的二分之一，且柄部為圓形，有利于排屑，故在加工相同直徑的孔時(shí)圓柄車刀的剛性明顯高于方柄車刀，所以在條件許可時(shí)應(yīng)盡量采用圓柄車刀。在臥式車床上因受四方刀架限制，一般多采用正方形或矩形柄車刀。如用圓柄車刀，為使刀尖處于主軸中心線高度，當(dāng)圓柄車刀頂部超過四方刀架的使用范圍時(shí)，可增加輔具后再使用。2、刀柄截面尺寸的選用。標(biāo)準(zhǔn)內(nèi)孔車刀已給定了可以小加工孔徑。對(duì)于加工可以大孔徑范圍，一般不超過比它大一個(gè)規(guī)格的車孔刀所定的可以小加工孔徑，如特殊需要，也應(yīng)小于再大一個(gè)規(guī)格的使用范圍。3、刀柄形式的選用。通常大量使用的是整體鋼制刀柄，這時(shí)刀桿的伸出量應(yīng)在刀桿直徑的4倍以內(nèi)。當(dāng)伸出量大于4倍或加工剛性差的工件時(shí)，應(yīng)選用帶有減振機(jī)構(gòu)的刀柄。如加工很高精度的孔，應(yīng)選用重金屬(如硬質(zhì)合金)制造的刀柄，如在加工過程中刀尖部需要充分冷卻，則應(yīng)選用有切削液送孔的刀柄。蘇州新型車刀加工</p></p><br
