style="text-indent:25px">數(shù)控加工用刀具材料必須根據(jù)所加工的工件和加工性質(zhì)來選擇。刀具材料的選用應(yīng)與加工對(duì)象合理匹配，切削刀具材料與加工對(duì)象的匹配，主要指二者的力學(xué)性能、物理性能和化學(xué)性能相匹配，以獲得較長(zhǎng)的刀具壽命和較大的切削加工生產(chǎn)率。切削刀具材料與加工對(duì)象的力學(xué)性能匹配：切削刀具與加工對(duì)象的力學(xué)性能匹配問題主要是指刀具與工件材料的強(qiáng)度、韌性和硬度等力學(xué)性能參數(shù)要相匹配。具有不同力學(xué)性能的刀具材料所適合加工的工件材料有所不同。① 刀具材料硬度順序?yàn)椋航饎偸毒?立方氮化硼刀具>陶瓷刀具>硬質(zhì)合金>高速鋼。② 刀具材料的抗彎強(qiáng)度順序?yàn)椋焊咚黉?硬質(zhì)合金>陶瓷刀具>金剛石和立方氮化硼刀具。③ 刀具材料的韌度大小順序?yàn)椋焊咚黉?硬質(zhì)合金>立方氮化硼、金剛石和陶瓷刀具。高硬度的工件材料，必須用更高硬度的刀具來加工，刀具材料的硬度必須高于工件材料的硬度，一般要求在60HRC以上。刀具材料的硬度越高，其耐磨性就越好。如，硬質(zhì)合金中含鈷量增多時(shí)，其強(qiáng)度和韌性增加，硬度降低，適合于粗加工；含鈷量減少時(shí)，其硬度及耐磨性增加，適合于精加工。</p><p style="text-indent:25px">非專門訂制的刀具主要是解決兩個(gè)問題，尺寸問題和表面粗糙度問題。一是尺寸問題，可以選擇一把尺寸與所需的尺寸相近的標(biāo)準(zhǔn)刀具，通過改磨就可以解決，但也需注意兩點(diǎn)：1，尺寸相差不能太大，一般不要超過2mm，因?yàn)槌叽缦嗖钐蟮脑挘瑫?huì)引起刀具的槽形發(fā)生變化，直接影響容屑空間和幾何角度；2，如果是帶有刃孔的立銑刀的話可以在普通機(jī)床上改磨，成本較低，如果是不帶刃孔的鍵槽銑刀就不能在普通機(jī)床上進(jìn)行，需要在專門的五軸聯(lián)動(dòng)機(jī)床上改磨，其成本也就會(huì)較高。二是表面粗糙度問題，可以通過對(duì)刃部的幾何角度的改變來實(shí)現(xiàn)，如加大前、后角的度數(shù)會(huì)明顯改善工件表面粗糙度。但如果使用方的機(jī)床剛性不夠的話，可能刃口倒鈍反而能提高表面粗糙度，這方面的東西非常復(fù)雜，需對(duì)加工現(xiàn)場(chǎng)分析后才能得出結(jié)論。非標(biāo)刀具是能提高生產(chǎn)效率的。</p><div

style="text-indent:25px">數(shù)控車床刀具分類分類：數(shù)控車削用的車刀一般分為三類，即尖形車刀、圓弧形車刀和成型車刀。一、圓弧形車刀，圓弧形車刀是較為特殊的數(shù)控加工用車刀。其特征是，構(gòu)成主切削刃的刀刃形狀為一圓度誤差或線輪廓度誤差很小的圓弧；該圓弧刃每一點(diǎn)都是圓弧形車刀的刀尖，因此，刀位點(diǎn)不在圓弧上，而在該圓弧的圓心上；車刀圓弧半徑理論上與被加工零件的形狀無關(guān)，并可按需要靈活確定或測(cè)定后確認(rèn)。當(dāng)某些尖形車刀或成型車刀（如螺紋車刀）的刀尖具有一定的圓弧形狀時(shí)，也可作為這類車刀使用。圓弧形車刀可以用于車削內(nèi)、外表面，特別適宜于車削各種光滑連接（凹形）的成型面。二、成型車刀，成型車刀俗稱樣板車刀，其加工零件的輪廓形狀完全由車刀刀刃的形狀和尺寸決定。數(shù)控車削加工中，常見的成型車刀有小半徑圓弧車刀、非矩形車槽刀和螺紋車刀等。在數(shù)控加工中，應(yīng)盡量少用或不用成型車刀，當(dāng)確有必要選用時(shí)則應(yīng)在工藝準(zhǔn)備文件或加工程序單上進(jìn)行詳細(xì)說明。數(shù)控刀具的分類有多種方法。東莞數(shù)控刀具</p><p
