The 3-D geometry of the blade鈥檚 casting is set up with measured data or offset from the designed model. CNC functions of the machine can be defined with relevant software, and the cutter鈥檚 3-D model can be established according to the geometrical parameters of the selected cutters. After that, the blade鈥檚 design model can be transformed in machining environments, and the tool-path of 5-axis machining can be computed. Combining these tool-paths with the simulation environment for multi-axis machining, the dynamic simulation for blade鈥檚 cutting process and the machine鈥檚 motion can be realized. Key words: NC machining; Computer simulation; Blade; Multi-axis simultaneous machining 1 寮曡█ 銆€銆€姘磋吉姗�(j墨)钁夌墖鐐哄京(f霉)闆滈洉濉戞洸闈㈤珨锛屽叾澶氳桓鑱�(li谩n)鍕曟暩(sh霉)鎺у姞宸ユ瘮涓€鑸浂浠跺京(f霉)闆淸1]銆傚湅鍏�(n猫i)鐝�(xi脿n)宸查枊鐧�(f膩)鍑虹殑澶у瀷钁夌墖浜旇桓鑱�(li谩n)鍕曞姞宸ュ伐钘�锛屼粛娌掓湁鍏ㄩ儴鍙栨秷瑭﹀姞宸ラ璀夐亷绋媅2]銆傚湪瑷堢畻姗�(j墨)涓婁豢鐪熼璀夊杌歌伅(li谩n)鍕曞姞宸ュ垁鍏疯粚璺★紝閫�(j矛n)琛屽姞宸ュ垁鍏峰共娑夊拰姗�(j墨)搴婅垏钁夌墖鐨勭鎾炴鏌�锛屽彇浠ｈ│鍒囧墛鎴栬│鍔犲伐閬庣▼锛屽皨姹傛渶鍎�(y艒u)鐨勫姞宸ユ柟娉曞拰宸ヨ棟鏂规锛屾棦鍙繚璀夊姞宸ュ瀷闈㈢殑婧�(zh菙n)纰烘€у拰钁夌墖鐨勮唱(zh矛)閲忥紝鍙堝彲鎻愰珮鍔犲伐鏁堢巼[3]銆� 2 钁夌墖澶氳桓鑱�(li谩n)鍕曟暩(sh霉)鎺у姞宸ヤ豢鐪熺挵(hu谩n)澧冪殑寤烘ā 銆€銆€鐢变簬澶у瀷姘磋吉姗�(j墨)钁夌墖鐨勫舰鐙€寰�(f霉)闆�锛岀洝绠″湪鏁�(sh霉)鎺х法绋嬫檪灏嶅悇绋洸闈㈤€犲瀷銆佸伐钘濊(gu墨)鍔�銆佸垁浣嶈(gu墨)鍔�銆佸悗缃檿鐞嗙瓑閮戒綔浜嗛潪甯镐粩绱�(x矛)鐨勫伐浣�锛屼絾鎵€鐢熸垚鐨勬暩(sh霉)鎺у姞宸ョ▼搴忎粛鍙兘鐧�(f膩)鐢熷涓嬪晱椤岋細鍔犲伐閬庣▼涓殑閬庡垏鑸囨瑺鍒�銆佸垁妗垮強鑱�(li谩n)鎺ョ郴绲�(t菕ng)鑸囬浂浠躲€佹(j墨)搴婂悇閬�(y霉n)鍕曢儴浠跺強澶惧叿闁撶殑骞叉秹纰版挒锛屼互鍙婂姞宸ラ亷绋嬩腑鍒囧墛鍒€鍏风殑閬庤矤(f霉)鑽风瓑[4]銆傚洜姝�锛屽湪鍔犲伐鍒€浣嶈粚璺℃垨绋嬪簭鐢熸垚鍚�锛屽繀闋堥€�(j矛n)琛屾纰烘€ф椹�锛岀洿鍒板舰鎴愬悎鏍肩殑鏁�(sh霉)鎺х▼搴�銆傚ぇ鍨嬭憠鐗囧姞宸ヤ豢鐪�锛岄鍏堥€�(j矛n)琛屽垏鍓婇亷绋嬪咕浣曚豢鐪熶互妾㈡煡鍔犲伐閬庣▼涓憠鐗囩殑閬庡垏鑸囨瑺鍒�锛岀劧鍚庨€�(j矛n)琛屾(j墨)搴婇亱(y霉n)鍕曚豢鐪熶互闃叉姗�(j墨)搴婇亱(y霉n)鍕曢儴浠剁鎾炲拰鍒€妗垮共娑�銆� 銆€銆€钁夌墖鏁�(sh霉)鎺у姞宸ヤ豢鐪熸槸灏囪憠鐗囩殑鐪熷鍔犲伐閬庣▼鍦ㄨ櫅鎿姞宸ョ挵(hu谩n)澧冧腑閫�(j矛n)琛屾槧灏勶紝鍗冲皪閲囩敤鐨勬暩(sh霉)鎺ф(j墨)搴�銆佸姞宸ュ垁鍏枫€佽憠鐗囨瘺鍧強澶惧叿绛夌湡瀵﹀姞宸ョ挵(hu谩n)澧冮€�(j矛n)琛屾槧灏�锛屾(g貌u)閫犲嚭浠跨湡锛堣櫅鎿殑锛夊姞宸ョ挵(hu谩n)澧�銆傚湪浠跨湡鐠�(hu谩n)澧冧笅锛岄€氶亷杌熶欢妯℃摤鍔犲伐鐠�(hu谩n)澧�銆佸垁鍏疯矾寰戝拰鏉愭枡鍒囬櫎閬庣▼锛屽緸鑰岄仈(d谩)鍒版ā鎿暩(sh霉)鎺у姞宸ラ亷绋嬬殑鐩殑銆備豢鐪熺挵(hu谩n)澧冪殑骞句綍寤烘ā鏄鐝�(xi脿n)鏁�(sh霉)鎺у姞宸ヤ豢鐪熺殑鍩虹(ch菙)锛屽湒1鏄桓娴佸紡姘磋吉姗�(j墨)钁夌墖鐨勫杌镐豢鐪熷姞宸ョ挵(hu谩n)澧�銆� 2.1 钁夌墖鍙婂叾姣涘澂鐨勪笁缍缓妯� 銆€銆€杌告祦寮忔按杓(j墨)钁夌墖鐢卞叿鏈夐洉濉戞洸闈㈢殑姝ｃ€佽儗闈�锛岄€�(j矛n)姘撮倞璁婂湏寮у崐寰戞洸闈�锛屽嚭姘撮倞鏇查潰锛岃吉绶ｇ悆闈㈠拰鏌遍潰锛岃吉绶ｇ殑瑁欓倞鏇查潰锛岃吉杞傚拰娉曡槶鐞冮潰锛岃吉杞傚拰娉曡槶鑸囨銆佽儗闈㈢殑閬庢浮鏇查潰绛夋(g貌u)鎴怺4]銆傝憠鐗囨銆佽儗闈㈡槸鎸夊湪鍦撴煴鍧愭(bi膩o)绯讳笅绲﹀嚭鐨勫瀷鍊奸粸(di菐n)锛岀法瀵竴鍊嬬▼搴�?q奴)鈶挎き杩璫(di菐n)鎸夊湏鏌辨埅闈㈣畝鍏ワ紝骞惰綁(zhu菐n)鎻涘埌鐩磋鍧愭(bi膩o)涓�锛屾部鍦撴煴鎴潰绶氫綔NURBS 鏇茬窔锛岀劧鍚庢斁妯ｏ紙LOFT锛夌敓鎴愯憠鐗囩殑姝�銆佽儗闈㈡洸闈�锛屽湪姝ゅ熀绀�(ch菙)涓�锛屽啀閫犲瀷鍑哄叾浠栨洸闈㈠鐝�(xi脿n)钁夌墖鐨勪笁缍咕浣曢€犲瀷锛屽鍦�2銆� 銆€銆€钁夌墖鐨勬瘺鍧暩(sh霉)鎿�(j霉)鍙互寰炰笁缍脯閲忓緱鍒扮殑榛�(di菐n)浜戦泦鏂瑰紡纰哄畾锛屽彲鏍规摎(j霉)钁夌墖姣涘澂涓夌董娓噺鐨勬暩(sh霉)鎿�(j霉)閫�(j矛n)琛屽咕浣曢€犲瀷锛屼絾鐢变簬姣忓€嬭憠鐗囨瘺鍧殑浣欓噺鍒嗗竷涓嶄竴妯�锛岄€欐ǎ鐨勫伐浣滈噺澶�銆傚湪瀵﹂殯宸ョ▼涓紝鍩轰簬钁夌墖鐨勪笁缍咕浣曢€犲瀷锛屽皣瑷�(sh猫)瑷堢殑妯″瀷閫�(j矛n)琛屽咕浣曡畩鎻�锛屾寜钁夌墖閼勯€犵殑骞冲潎浣欓噺閫�(j矛n)琛屾洸闈㈠亸缃敓鎴愭瘺鍧洸闈�锛屽苟绺悎鎴愬楂斾綔鐐烘瘺鍧殑骞句綍妯″瀷銆� 銆€銆€灏嶄簬杌告祦寮忔按杓(j墨)钁夌墖锛屾牴鎿�(j霉)钁夌墖鐨勭壒榛�(di菐n)锛屾寜鍏跺伐钘濊(gu墨)鍔冮噰鐢ㄤ互钁夌墖鏃嬭綁(zhu菐n)杌稿績绶氱偤瀹氫綅鍩烘簴(zh菙n)銆傚叾瑁濆ぞ鏂规鏄湪钁夌墖鐨勮吉绶ｄ笂鐒婃帴宸ヨ棟杌�銆傜矖杌婃硶铇闈�锛屽苟鍦ㄦ硶铇闈腑蹇冨拰宸ヨ棟杌镐腑蹇冩墦鍏╁€嬮爞灏栧瓟銆傜浉鎳�(y墨ng)鐨勫ぞ鍏风敤鍏╅爞灏栧骇锛屽浐瀹氱缃簬娉曡槶涓�锛岃桓鍚戝彲瑾�(di脿o)闋傚皷搴�锛岀疆浜庤吉绶ｄ笂鐨勫伐钘濊桓绔�銆� 鍦�2 钁夌墖鐨勪笁缍咕浣曢€犲瀷 鍦�3 钁夌墖澶氳桓鍔犲伐鐨勬(j墨)搴婁豢鐪� 2.2 鏁�(sh霉)鎺у姞宸ユ(j墨)搴婄殑寤烘ā 锛�1锛� 姗�(j墨)搴婄殑骞句綍寤烘ā 銆€銆€鐐轰豢鐪熻憠鐗囧姞宸ョ殑鏁村€嬮亷绋�锛屾鏌ュ垁鍏烽亱(y霉n)鍕曡粚璺★紝鏄惁鐧�(f膩)鐢熺鎾�銆佸共娑夌従(xi脿n)璞＄瓑锛屽皪鍔犲伐涓瓨鍦ㄧ殑鍟忛鍔犱互淇锛屽繀闋堟牴鎿�(j霉)瀵﹂殯鍔犲伐姗�(j墨)搴婃垨鍔犲伐涓績鐨勭媭娉佸湪瑷堢畻姗�(j墨)涓婃(g貌u)閫犱竴鍊嬮€肩湡鐨勮櫅鎿殑鏁�(sh霉)鎺у垏鍓婂姞宸ョ挵(hu谩n)澧冦€傛暩(sh霉)鎺у姞宸ユ(j墨)搴婄殑寤烘ā鍖呮嫭姗�(j墨)搴婄殑骞句綍寤烘ā鍜屾(j墨)搴婄殑鏁�(sh霉)鎺х郴绲�(t菕ng)锛圕NC锛夊畾缇�銆傚湪姗�(j墨)搴婂咕浣曞缓妯￠亷绋嬩腑锛屽繀闋堟牴鎿�(j霉)鎵€閲囩敤鐨勬(j墨)搴婄殑绲�(ji茅)妲�(g貌u)銆佸叿楂斿昂瀵哥殑澶у皬鍙婄浉鎳�(y墨ng)浣嶇疆锛屽湪閫犲瀷鏅傚皪浜庨亱(y霉n)鍕曢儴浠剁殑澶栧瀷鍜屽昂瀵镐笉鑳界啊鍖�锛屼絾灏嶄簬涓€浜涢潪閬�(y霉n)鍕曢儴浠剁殑澶栧瀷鍙互閬╃暥(d膩ng)绨″寲銆傚湪姝ゅ師鍓囦笂閲囩敤鐩搁棞(gu膩n)鐨勮粺浠跺彲妲�(g貌u)閫犲嚭鐨勪豢鐪熷闅涘姞宸ユ(j墨)搴婄殑骞句綍妯″瀷銆傚湪瀹氱京涓€鑷烘(j墨)搴婃檪锛屽亣瑷�(sh猫)鎵€鏈夌殑姗�(j墨)搴婇儴浠堕兘铏曚簬瀹冨€戠浉鎳�(y墨ng)鐨勯浂榛�(di菐n)浣嶇疆銆傚湒3鐐哄皪浜庝竴鑷哄姞宸ヨ憠鐗囩殑浜旇桓鑱�(li谩n)鍕曞姞宸ユ(j墨)搴婄殑骞句綍寤烘ā銆� 锛�2锛� 姗�(j墨)搴婄殑鏁�(sh霉)鎺х郴绲�(t菕ng)锛圕NC锛夊姛鑳藉畾缇� 銆€銆€鎸夎憠鐗囩殑鍔犲伐宸ヨ棟瑕�(gu墨)鍔�锛岄噰鐢ㄥ鍦�3鎵€绀虹殑榫嶉杸绉诲嫊寮忎簲杌歌伅(li谩n)鍕曟暩(sh霉)鎺у姞宸ユ(j墨)搴�銆傚姞宸ヨ憠鐗囬噰鐢ㄥ杌歌伅(li谩n)鍕曟柟寮�锛屽嵆X锛孻锛孼涓夊€嬬洿绶氳桓锛屽叐杌告暩(sh霉)鎺ч姂闋殑褰㈡垚涓€鍊嬫棆杞�(zhu菐n)杌窩鍜屼竴鍊嬫摵鍕曡桓B銆傝┎姗�(j墨)搴婅鏈塆E Fanuc鏁�(sh霉)鎺х郴绲�(t菕ng)锛屽皣閬稿畾鍔犲伐姗�(j墨)搴婄殑鏁�(sh霉)鎺х郴绲�(t菕ng)鐨勬寚浠や唬纰�銆佽獮娉曟寜浠跨湡杌熶欢瑕�(gu墨)瀹氶€�(j矛n)琛屽畾鍒�锛岀敓鎴怌NC浠ｇ⒓缈昏鍣�銆傚畾缇╂(j墨)搴婂悇閬�(y霉n)鍕曡桓鐨勫潗妯�(bi膩o)绯婚棞(gu膩n)绯�銆侀亱(y霉n)鍕曢棞(gu膩n)绯�銆佽绋嬮檺鍒躲€侀€�(j矛n)绲﹂€熷害闄愬埗銆佹(j墨)妲�(g貌u)閬�(y霉n)鍕曞壇鐨勯棞(gu膩n)绯汇€丆NC鎺у埗鐨勫潗妯�(bi膩o)杌歌伅(li谩n)鍕曢棞(gu膩n)绯荤瓑锛岀敓鎴愪竴鍊嬫(j墨)搴婇厤缃枃浠讹紝鍗冲彲瀵︾従(xi脿n)浠跨湡鏁�(sh霉)鎺х郴绲�(t菕ng)鍔熻兘鐨勫畾缇�銆� 2.3 鍔犲伐鍒€鍏峰缓妯� 銆€銆€鍦ㄦ暩(sh霉)鎺у姞宸ヨ憠鐗囨檪锛岄嚌灏嶈憠鐗囧悇鍔犲伐闈㈢殑鐗归粸(di菐n)锛屽繀闋堥噰鐢ㄤ笉鍚岀ó椤�銆佷笉鍚岃(gu墨)鏍肩殑澶氱ó鍒€鍏凤紝濡傚湪鍔犲伐澶у瀷杌告祦寮忔按杓(j墨)钁夌墖鏅備娇鐢ㄧ殑鍒€鍏风偤绮�銆佺簿闈㈤姂鍒€锛岃灪鏃嬬帀绫崇珛閵戝垁锛岀悆闋姂鍒€绛�銆傜偤浜嗗湪鍒囧墛浠跨湡閬庣▼涓兘澶犳鏌ュ嚭鍔犲伐閬庣▼涓憠鐗囩殑閬庡垏鑸囨瑺鍒�锛屽繀闋堟牴鎿�(j霉)鍚勫姞宸ュ垁鍏风殑骞句綍鍙冩暩(sh霉)婧�(zh菙n)纰哄缓绔嬪垁鍏风殑涓夌董骞句綍妯″瀷銆傚湪鍒€鍏峰缓妯℃檪锛屽彲浠ュ彧鑰冩叜鍒€鍏峰姞宸ュ洖杞�(zhu菐n)鐢�(ch菐n)鐢熺殑澶栧舰鐨勫咕浣曞弮鏁�(sh霉)锛屽彟澶栦篃蹇呴爤寤虹珛鍒€妗�銆佸垁鍏疯伅(li谩n)鎺ョ郴绲�(t菕ng)鐨勫咕浣曟ā鍨嬨€� 3 钁夌墖澶氳桓鑱�(li谩n)鍕曟暩(sh霉)鎺у姞宸ヤ豢鐪熺ず渚� 銆€銆€灏嶄竴鐩村緫鐐篺5.8m杌告祦寮忔按杓(j墨)杞�(zhu菐n)杓憠鐗�锛岄噰鐢ㄤ簲杌歌伅(li谩n)鍕曟暩(sh霉)鎺у姞宸ャ€傛牴鎿�(j霉)瑷�(sh猫)瑷堝湒绱欏湪UG涓婂畬鎴愯憠鐗囩殑涓夌董閫犲瀷濡傚湒2锛屽皣钁夌墖鐨勪笁缍ā鍨嬭畩鎻涘埌鍔犲伐浣嶇疆锛屽啀閫氶亷UG瑷堢畻鍑轰簲杌歌伅(li谩n)鍕曞垁鍏疯粚璺�銆傚皣瑭插垁鍏疯粚璺¤綁(zhu菐n)鍏ユ垜鍊戦枊鐧�(f膩)鐨勮憠鐗囧杌歌伅(li谩n)鍕曟暩(sh霉)鎺у姞宸ヤ豢鐪熻粺浠堕€�(j矛n)琛屽嫊鎱�(t脿i)鐨勫垏鍓婇亷绋嬬殑鍒€浣嶈粚璺′豢鐪熷鍦�4锛屾(j墨)搴婇亱(y霉n)鍕曚豢鐪熷鍦�3銆傚皪浜庢煇涓€娣锋祦寮忔按杓(j墨)钁夌墖閫�(j矛n)琛屽嫊鎱�(t脿i)鐨勫垏鍓婇亷绋嬬殑骞句綍浠跨湡濡傚湒5銆� 鍦�4 鍔犲伐閬庣▼涓殑鍒€浣嶈粚璺′豢鐪� 鍦�5 鍒囧墛閬庣▼鐨勫咕浣曚豢鐪� 4 绲�(ji茅)鏉熻獮 銆€銆€閲濆皪姘磋吉姗�(j墨)钁夌墖澶氳桓鑱�(li谩n)鍕曟暩(sh霉)鎺у姞宸ョ殑浠跨湡鐠�(hu谩n)澧冨缓绔嬫柟娉�锛屽凡鐢ㄤ簬宸ョ▼瀵﹂殯澶у瀷钁夌墖鏁�(sh霉)鎺у姞宸ョ法绋嬮亷绋嬩腑鐨勭▼搴忔椹楀拰鍔犲伐鏂规鍎�(y艒u)鍖栥€傞€氶亷浠跨湡鍔犲伐锛屼笉鍍呮湁鏁堝湴淇濊瓑浜嗗姞宸ヨ唱(zh矛)閲忓拰瑷�(sh猫)鍌欏畨鍏�锛岃€屼笖鍙栨秷浜嗚憠鐗囩殑鈥滆│鍔犲伐鈥濋亷绋�锛屽苟宸叉垚鐐哄ぇ鍨嬭憠鐗囨暩(sh霉)鎺у姞宸ョ法绋嬮亷绋嬩腑妾㈤绋嬪簭鍜屽劒(y艒u)鍖栧姞宸ユ柟妗堝繀涓嶅彲灏戠殑鎵嬫銆� 鍙冭€冩枃鐛�(xi脿n)锛� [1] Xi-de Lai, Yun-fei Zhou, Ji Zhou, at al.
