Chii chinoita cnc machining

Nhamba inodzorwa (CNC) machining inzira yekugadzira iyo maindasitiri mazhinji akabatanidza mumaitiro avo ekugadzira.Izvi zvinodaro nekuti kushandiswa kwemichina yeCNC kunogona kuwedzera kugadzirwa.Inobvumirawo huwandu hwakawanda hwemashandisirwo pane mashini anoshanda nemaoko.

Iko kushanda kweiyo CNC process inosiyanisa, uye nekudaro inotsiva, izvo zvinogumira zvemanyoro machining, izvo zvinoda kuti mutyairi wemunda akurumidze uye atungamirire mirairo yechishandiso chemuchina kuburikidza nemalever, mabhatani, uye mavhiri emaoko.Kune anoona, CNC system inogona kufanana neyakajairwa seti yezvikamu zvekombuta.

CNC machining inoshanda sei?

Kana iyo CNC system yaitwa, iwo anodiwa machining dimensions anoiswa musoftware uye anopihwa kune anowirirana maturusi nemichina, iyo inoita mabasa akapihwa ekuyera, senge marobhoti.

Muchirongwa cheCNC, majenareta ekodhi mumasisitimu edhijitari anowanzo fungidzira kuti iyo meshini haina kukanganisa, kunyangwe paine mukana wekukanganisa, izvo zvinowanzoitika kana muchina weCNC uchirairwa kucheka munzira dzakawanda panguva imwe chete.Kuiswa kwezvishandiso muCNC kunotsanangurwa nenhevedzano yezvekupinda inonzi chikamu zvirongwa.

Uchishandisa CNC muchina, isa chirongwa kuburikidza punch makadhi.Mukupesana, zvirongwa zve CNC muchina maturusi anopinzwa mukombuta kuburikidza nekiyipadhi.CNC programming inoramba iri mundangariro dzekombuta.Iyo kodhi pachayo inonyorwa uye inogadziriswa nevagadziri vepurogiramu.Naizvozvo, CNC masisitimu anopa huwandu hwakakura hwekugona komputa.Chinonyanya kukosha, CNC masisitimu haana kana static, sezvo zvakagadziridzwa zvinokurudzira zvinogona kuwedzerwa kuzvirongwa zvakagara zviripo nekugadzirisa kodhi.

CNC muchina kuronga

Mukugadzira CNC, michina inoshandiswa kuburikidza nenhamba yekudzora, umo chirongwa chesoftware chinotsanangurwa kudzora zvinhu.Mutauro uri kuseri kweCNC machining, unozivikanwawo seG-code, unoshandiswa kudzora maitiro akasiyana emuchina unoenderana, senge kumhanya, chiyero chekudya, uye kurongeka.

Chaizvoizvo, CNC machining pre-zvirongwa kumhanya uye chinzvimbo chemichina inoshanda uye inovamhanyisa kuburikidza nesoftware mukudzokorora, kutenderera kutenderera nekusina kana kupindira kwevanhu.Munguva yeCNC machining, 2D kana 3D CAD dhizaini inoumbwa uye yozoshandurwa kuita komputa kodhi yekuurayiwa neCNC system.Mushure mekupinda purogiramu, mutyairi anoiedza-inoimhanyisa kuti ave nechokwadi chekuti hapana zvikanganiso mukukodha.

Nekuda kwehunyanzvi uhu, iyo nzira yakagamuchirwa mumakona ese eindasitiri yekugadzira, uye CNC kugadzira kunonyanya kukosha mukugadzirwa kwesimbi nemapurasitiki.Dzidza zvakawanda nezve rudzi rwemachining sisitimu inoshandiswa uye maitiro eCNC muchina hurongwa anogona zvizere kugadzira CNC kugadzira pazasi:

Vhura / Yakavharwa Loop Machining Systems

Mukugadzira CNC, kutonga kwenzvimbo kunotemerwa neyakavhurika-loop kana yakavharwa-loop system.Kune yekutanga, chiratidzo chinomhanya munzira imwechete pakati peCNC uye mota.Mune yakavharwa-loop system, mutongi anokwanisa kugamuchira mhinduro, izvo zvinoita kuti kukanganisa kugadziriswe.Saka, iyo yakavharwa-loop system inogona kugadzirisa kukurumidza uye kusarongeka kwenzvimbo.

MuCNC machining, kufamba kunowanzo kutungamirwa kune X uye Y axes.Nekudaro, chishandiso chinomisikidzwa uye chinotungamirwa neanotsika kana servo motors anodzokorora mafambiro chaiwo akatemwa neG-code.Kana simba uye velocity zvidiki, maitiro anogona kuitiswa neakavhurika loop control.Kune zvimwe zvese, yakavharwa-loop kudzora kwekumhanya, kuwirirana, uye kurongeka kunodiwa kugadzirisa kugadzira, senge zvigadzirwa zvesimbi, zvinodikanwa.

CNC machining izere otomatiki

Mumazuva ano eCNC protocol, kugadzirwa kwezvikamu kuburikidza ne-pre-programmed software kunowanzoitwa otomatiki.Shandisa komputa-inobatsira dhizaini (CAD) software kuseta zviyero zvechikamu chakapihwa, wobva washandisa komputa-inobatsira kugadzira (CAM) software kuishandura kuita chigadzirwa chaicho chakapedzwa.

Chero ipi zvayo yakapihwa workpiece inogona kuda akasiyana maturusi emuchina, senge madhiri nekucheka.Kuti isangane nezvido izvi, michina yemazuva ano mizhinji inosanganisa mabasa akati wandei kuita yuniti imwe.

Neimwe nzira, yuniti inogona kuve nemichina yakawanda uye seti yemarobhoti anofambisa zvikamu kubva kune imwe application kuenda kune imwe, asi zvese zvinodzorwa nechirongwa chimwe chete.Pasinei nekuseta, CNC machining inogonesa kumisikidzwa kwechikamu kugadzirwa kwakaoma nemanyorero machining.

Mhando dzakasiyana dze CNC michina

Michina yekutanga yeCNC yakadzokera kuma1940, apo mota dzemagetsi dzakatanga kushandiswa kudzora kufamba kwezvishandiso zviripo.Sezvo tekinoroji yakafambira mberi, aya masisitimu akawedzerwa neanalog uye pakupedzisira makombiyuta edhijitari, zvichikonzera kukwira kweCNC machining.

CNC milling muchina

CNC zvigayo zvinokwanisa kumhanyisa zvirongwa zvine nhamba uye alphanumeric cues inotungamira workpiece pamadaro akasiyana.Kugadzirira muchina wekugaya kunogona kuve kwakavakirwa paG-code kana mumwe mutauro wakasiyana wakagadzirwa nechikwata chekugadzira.Michina yekugaya ine matatu-axis system (X, Y, uye Z), asi zvigayo zvizhinji zvine matemo matatu.

lathe

Nerubatsiro rweCNC tekinoroji, lathe inogona kucheka nehupamhi hwepamusoro uye nekumhanya kwakanyanya.CNC lathes inoshandiswa kune yakaoma machining iyo yakaoma kuwana pane zvakajairika muchina shanduro.Kazhinji, mabasa ekutonga eCNC milling machines uye lathes akafanana.Senge CNC milling muchina, lathes anogona zvakare kumhanya neg-code control kana imwe kodhi pane lathe.Nekudaro, mazhinji CNC lathes anoumbwa nematemo maviri - X uye Z.
