Iziko lomatshini le-CNC lifuna ukwenza ezi zinto kakuhle ukusika isinyithi

Okokuqala, intshukumo yokuguqula kunye nomgangatho owenziweyo

Ukuguqula ukunyakaza: Kwinkqubo yokusika, ukwenzela ukuba kususwe isinyithi esingaphezulu, i-workpiece kunye nesixhobo kufuneka sinqunywe ngokubhekiselele komnye nomnye.Ukuhamba kwentsimbi engaphezulu kwi-workpiece ngesixhobo sokujika kwi-lathe kubizwa ngokuba yi-turning motion, enokwahlulwa ibe yintshukumo ephambili kunye nokuqhubela phambili.Yenza umthambo.

Ukunyakaza kokutya: Uluhlu olutsha lokusika luhlala lufakwa kwintshukumo yokusika.Intshukumo yokutya sisindululo ecaleni komphezulu womsebenzi oza kwenziwa, onokuthi ube sisindululo esiqhubekayo okanye intshukumo ephakathi.Ngokomzekelo, i-lathe e-horizontal ihamba ngokuqhubekayo ngexesha lokuhamba kwesixhobo sokuguqula, kwaye intshukumo yokutya ye-workpiece kwi-head planer yi-intermittent motion.

Umphezulu owenziwe kwi-workpiece: Ngexesha lenkqubo yokusika, umphezulu owenziwe ngomatshini, umphezulu owenziwe ngomatshini kunye nomgangatho owenziwe ngomatshini wenziwa kwi-workpiece.Umphezulu owenziwe ngoomatshini ngumhlaba omtsha owenziwe ngokukhutshwa kwesinyithi esingaphezulu.Umphezulu oza kucutshungulwa ubhekisa kumphezulu apho umaleko wesinyithi oza kusikwa kuwo.Umphezulu owenziwe ngomatshini ngumgangatho apho i-edge yokuguqula isixhobo ijika.cnc machining inxalenye

Intshukumo ephambili: unqumle ngokuthe ngqo umaleko wokusika kwi-workpiece kwaye uyiguqule ibe yi-chips, ngaloo ndlela wenze intshukumo yobuso obutsha bomsebenzi, obizwa ngokuba sisindululo esiphambili.Xa usika, ukunyakaza okujikelezayo kwe-workpiece yeyona nto iphambili.Ngokuqhelekileyo, isantya sentshukumo ephambili siphezulu, kwaye amandla okusika asetyenzisiweyo makhulu.cnc ukujika inxalenye

 
Okwesibini, inani lokusika iziko lomatshini libhekisa kubunzulu bokusika, isantya sokutya kunye nesantya sokusika.cnc yokugaya inxalenye

(1) Ukusika ubunzulu: ap = (dw - dm) / 2 (mm) dw = ububanzi bomsebenzi ongenamashini dm = ububanzi bomsebenzi owenziwe ngomatshini, ubunzulu bokusikwa yinto esihlala siyibiza ngokuba sisixa semela.

Ukukhethwa kobunzulu bokusika: Ubunzulu bokusika i-αp kufuneka bumiselwe ngokwesibonelelo somatshini.Xa urhabaxa, ngaphandle kwesibonelelo esiseleyo, isibonelelo sokurhabaxa kufuneka sinqunyulwe kangangoko kunokwenzeka.Oku akunakuqinisekisa kuphela imveliso yokusika ubunzulu, izinga lokutya ƒ, ukusika isantya V enkulu phantsi kwesiseko sokuqinisekisa iqondo elithile lokuqina, kodwa kunokunciphisa inani lokupasa, kwaye ufuna ukufunda inkqubo yokulawula amanani e-UG kwiqela le-QQ. I-304214709 ingafumana idatha.Kwimeko yokugqithiswa kwesibonelelo somatshini okanye ukungonelanga kokuqina kwenkqubo yenkqubo okanye ukungonelanga kwe-blade amandla, kufuneka ihlulwe ibe ngamabini amabini okanye ngaphezulu.Ngeli xesha, ubunzulu bokusika bokupasa kokuqala kufuneka buthathwe bukhulu, obunokuthi bube ne-2/3 ukuya kwi-3/4 yesibonelelo esipheleleyo;kwaye ubunzulu bokusika ukupasa kwesibini buncinci ukufumana inkqubo yokugqiba.Amaxabiso eparamitha yobunzima obuncinci bomgangatho kunye nokuchaneka okuphezulu komatshini.

Xa umphezulu wecandelo lokusika unezinto eziqinileyo ezifana ne-cast, i-forged okanye i-stainless steel, ubunzulu bokusika kufuneka budlule ubunzima okanye i-chill layer ukuze ugweme ukusika umgca wokusika kwi-hard or chill layer.

(2) Ukhetho lwemali yokutya: ukufuduswa okuzalanayo kwesixhobo sokusebenza kunye nesixhobo kwicala lentshukumo yokutya, kwiiyunithi ze-mm, ngokwenguquko nganye okanye ngokubuyisela isixhobo okanye isixhobo.Emva kokuba ubunzulu bokunqunyulwa bukhethiwe, ireyithi yokutya enkulu kufuneka ikhethwe kangangoko kunokwenzeka.Ukukhethwa kwexabiso elifanelekileyo lesantya sokutya kufuneka kuqinisekise ukuba isixhobo somatshini kunye nesixhobo asonakaliswa ngamandla okusika kakhulu.Ukuphambuka kwendawo yokusebenza okubangelwa amandla okusika akudluli ixabiso elivumelekileyo lokuchaneka kwe-workpiece, kwaye ixabiso lepharamitha ye-roughness ye-surface ayinkulu kakhulu.Xa urhabaxa, umda wokutya ubukhulu becala ngamandla okusika.Xa i-semi-ukugqiba kunye nokugqiba, umda wokutya ubukhulu becala buburhabaxa bomphezulu.

(3) Ukukhethwa kwesantya sokusika: Isantya esikhawulezayo sephuzu kwinqanaba lokusika isixhobo esinxulumene nomphezulu oza kusetyenziswa kwindlela ehamba phambili ehamba phambili ngexesha lokusika, iyunithi i-m / min.Xa ubunzulu bokusika i-αp kunye nemali yokutya ƒ ikhethiwe, isantya esiphezulu sokusika sikhethwa ngokwesiseko sabanye, kwaye ulwalathiso lophuhliso lwenkqubo yokusika luyi-high-speed machining.

 

 

Okwesithathu, uburhabaxa ingcamango yomatshini

Kwi-mechanics, uburhabaxa bubhekiselele kwiimpawu zejiyometri ezincinci zeepatshi ezincinci kunye neencopho kunye neentlambo kumphezulu owenziwe ngomatshini.Yenye yeengxaki zophando lokutshintshelana.Uburhabaxa bomphezulu ngokuqhelekileyo bubunjwa ziindlela zokusetyenzwa ezisetyenzisiweyo kunye nezinye izinto, ezifana nokungquzulana phakathi kwesixhobo kunye nomphezulu wenxalenye ngexesha lokucubungula, ukuguqulwa kweplastiki yentsimbi yomphezulu ngexesha lokwahlulwa kwetshiphu, kunye nokungcangcazela kwamatyeli amaninzi kwinkqubo yenkqubo.Ngenxa yomehluko phakathi kwendlela yokucubungula kunye nempahla ye-workpiece, umphezulu oza kucutshungulwa ushiya uphawu kunye nokwahlukana kobunzulu, ubuninzi, imilo kunye nokuthungwa.Uburhabaxa bomphezulu bunxulumene ngokusondeleyo neempawu zoomatshini, ukumelana nokunxiba, amandla okudinwa, ukuqina koqhagamshelwano, ukungcangcazela kunye nengxolo yamalungu omatshini, kwaye kunempembelelo ebalulekileyo kubomi benkonzo kunye nokuthembeka kweemveliso zoomatshini.

 

 

Okwesine, ukumela uburhabaxa

Emva kokuba umphezulu wenxalenye utshintshwe, ukhangeleka kakhulu kwaye awulingani xa ujongwa.Uburhabaxa bomphezulu bubhekiselele kwiifitsha zejiyometri ezincanyana ezincinci kunye neencopho ezincinci kunye neentlambo kumphezulu wenxalenye yomatshini, ezithi ngokubanzi zenziwe yindlela yokucubungula kunye/okanye ezinye izinto ezithathiweyo.Umsebenzi womphezulu wenxalenye wahlukile, kwaye umgangatho ofunekayo weparamitha yobunzima obufunekayo nawo ahlukile.Ikhowudi yomphezulu woburhabaxa iphawulwe kwinxalenye yomzobo ukubonisa iimpawu zomphezulu ekufuneka ziphunyezwe emva kokuba umphezulu ugqityiwe.Kukho iintlobo ezintathu zeeparamitha zobude boburhabaxa bomphezulu:

1. Ulwandlalo lwe-arithmetic ithetha ukutenxa Ra

I-arithmetic intsingiselo yomgama opheleleyo phakathi kwendawo ekwi-contour ecaleni kwendlela yokulinganisa (Y direction) kunye nomgca wereferensi phezu kobude besampulu.

2, ukungalingani micro 10 amanqaku ukuphakama Rz

Ibhekisa kwisambuku somndilili wencopho ezintlanu ezinkulu zomphakamo kunye nomndilili wobunzulu bentlambo yecontour ezintlanu ezinkulu ngaphakathi kobude besampulu.

I-3, ukuphakama okuphezulu kwe-contour Ry

Umgama phakathi kowona mgca wencopho uphezulu kunye nomgca ophantsi weprofayile ngaphezu kobude besampulu.

Okwangoku, uRa.isetyenziswa ikakhulu kushishino lokwenziwa koomatshini ngokubanzi.

 

 

Okwesihlanu, Isiphumo soburhabaxa ekusebenzeni kwenxalenye

Umgangatho womphezulu emva kokwenziwa komatshini we-workpiece uchaphazela ngokuthe ngqo izinto eziphathekayo, iikhemikhali kunye nezixhobo ze-workpiece.Ukusebenza komsebenzi, ukuthembeka kunye nobomi benkonzo yomsebenzi kuxhomekeke kumlinganiselo omkhulu kumgangatho ophezulu wenxalenye ephambili.Ngokubanzi, iimfuno zomgangatho ophezulu wezinto ezibalulekileyo okanye ezibalulekileyo ziphezulu kunezo zixhobo eziqhelekileyo, kuba iinxalenye ezinomgangatho ophezulu womphezulu ziya kuphucula kakhulu ukuxhathisa ukunxiba, ukuxhathisa ukubola kunye nokumelana nokukhathala.
