Naizvozvo, nyanzvi zhinji dzakazvipira kumisikidza chivakwa chitsva, ndiko kuti, chivakwa chakavhurika Iri rinotarisa pane yakavhurika yekuvaka uye yenhamba yekudzora hurongwa hwakazara, tichifunga nzira yekuvandudza iyo machining kurongeka, nekuisa pamberi peiyo calibration zano. ye-off-performance nhamba yekudzora system mune yakavhurika chimiro.I. sumo pfupi yekuvakwa kweiyo yakavhurika A-mhando yekudzora system.Iyo manhamba yekudzora sisitimu yakakosha muto komputa system, iyo inoshandiswa kune indasitiri yekudzora munda, asi yakasiyana neyakajairwa komputa.Kwenguva yakareba, iyo nhamba s system yakagadziridzwa kuita yayo pachayo system.Gadzira yavo yakapfava stem chimiro, shandisa kuvanzika kwehunyanzvi uye chisimbiso chehunyanzvi, kuitira kuti zviome kune vanogadzira maturusi emuchina uye vashandisi vekupedzisira kuita kusimudzira kwechipiri, uye kukudziridza kugona kwemuchina chishandiso uye NC system.Kana iyo yekudzidzisa uye yekudzora muchina chishandiso ichipinda mune yakagoverwa kutonga uye inochinjika mbiru yekugadzira system nharaunda, uye inotoda kutaurirana neyakajairwa network masisitimu akadai seCAD / CAPP / CAM, Mimwe CNC michina yakanangana nemabasa ega haina kukwana, uye itsva. zvakatipoteredza kuzadza zvinodiwa."Chishandiso ichi chinoshandurwa zvakare kuita yakavhurika CNC system.
Iyo yakavhurika yekuvaka Yi Trent inotora block hierarchical junction HN uye inopa yakabatana application yekubatanidza P kuburikidza nemhando dzakasiyana siyana, inotakurika.
Scalability, interoperability uye scalability, ndiko kuti, kuvhurika kwemukati kwehurongwa hwekuumbwa uye kuvhurika pakati pezvikamu zvehurongwa.2. Maererano nehurongwa hwehurongwa, basket performance CNC system control strategy inobva pane yakashama chimiro inoumbwa nezvikamu zvitatu: servo controller, multi FFI detector uye ruzivo rwekubatanidza, uye digital value processor, sezvinoratidzwa muKL 1, Chendai processing system. inotsigirwa netantalum system.Pamberi pezvikamu zveiyo servo system inogona kuita yakakosha m chikamu mukurongeka kweiyo workpiece, nzvimbo zhinji dzemaindasitiri dzakashongedzerwa servo masisitimu.Aya servo m masisitimu anoshandisa echinyakare imba 0 anti library library, ayo ari kuwedzera kufarirwa nezvinodiwa zvekuvimbika.Kudzora kwechinyakare kumhanya senge kurongeka kwebasa hakuchavepo - s iyi yepamusoro-inoshanda yakasimba yekufamba kutonga kwakakosha.Chinangwa chayo ndechekuziva kuti iyo yezita congruence kukanganisa iri padyo nefi resolution tambo.Kuti uone kusarudzwa kwakazara kweeuropium, senge engineering, kuchine hondo dzakawanda dzepeach.FT ndicho chikonzero chikuru, kunyanya panyaya yeanti dynamic uye nonlinear chiziviso chisina chokwadi m, iyo-kumhanya yakakwira dhigirii servo controller yakagadzirwa.Kana iyo shoma bandwidth servo controller inoshandiswa, iyo europium coupling kunonoka inova chikonzero chikuru chekukanganisa kwechinzvimbo, izvo zvinokanganisa geometric degree yeworkpiece.Iyo flsf system inofanirwa kunge iine cesium yekugadzirisa tsvimbo uye performance sting rod.Kana ma paramita eiyo dynamic system gomba achinja, Kuita kwakanaka kwazvo.Aya mambure 1 achave akanyanya kuomarara nekuwedzera kwekumhanyisa kwekudya panguva yekurova.Paunenge uchigadzira yepamusoro-inoshanda tsvimbo inofamba controller, aya h rubs anofanirwa kunge ari pazinc feed friction muripo wakataurwa naColm uye totnimfca.Iyo yakazara dhizaini dhizaini inobatanidza dhizaini detector, chinzvimbo anti library library control charmer uye fractionator, kureva, iyo yepamusoro-inoshanda yakavigwa system (DOB) yakavakirwa pane dhizaini detector, Disturbance gauge Iyo feedforward FFI controller inogona kutora s-optimal kuyerwa kutonga. .Zero chikamu chikanganiso chekutevera W. repetitive control skew kuti uvandudze kurongeka kwehuwandu, uye chigaro chemhinduro chekutonga chinowanzotora PID control.Kune nonlinear friction force compensation, nzira dzinowanzo shandiswa ndeidzi: online compensation method based on exponential nonlinear function, based on Neural network inverse controller compensation method, robust repetitive control and variable structure control.Nekudaro, kana masisitimu ma paramita achinja zvakanyanya kana paine kukurumidza kukurumidza mukufamba trajectory, DOB haina kunyatso kufanira.Yao uye tamizuka vakakurudzira nzira itsva yekudzora kufamba, inova adaptive robust control.Iyo basket performance servo system yakavakirwa pane adaptive robust control ine yakanaka yekutevera kuita.
Multi sensor yekuona uye fusion yeruzivo mubasket performance process, nzira dzakajairwa dzekunyatso gadzira bhasiketi dzinosanganisira kukanganisa tekinoroji yakavakirwa pakurongeka kwebhasiketi muchina chishandiso uye kukanganisa muripo tekinoroji zvichibva pakubvisa iko kukanganisa pachako.Chinangwa chenzira mbiri idzi ndechekuderedza kukanganisa kwekugadzira kwezvikamu.Iri bepa rinotora workpiece uye NC system seyakabatana yakazara, inofunga nzira yekuvandudza bhasikiti machining kurongeka, uye inobatanidza workpiece uye NC system kuburikidza neMulti-sensor Detection.Kuenzaniswa neine imwe sensor system, yakawanda-sensor ruzivo fusion system ine zvakanakira huwandu hukuru hweruzivo, yakanaka kushivirira kukanganisa uye kuwana ruzivo rwehunhu husingawanikwe nesenso imwe chete.Iyo machining process inzira yakaoma kwazvo uye inoshanduka, uye shanduko yenzvimbo, kumhanya, tembiricha uye simba rekucheka zvinokanganisa mumwe nemumwe.Chete nekusimbisa kuunganidza, kuzivikanwa uye kugadzirisa ruzivo urwu uye kuwana data rakavimbika rinogona kudzorwa nemazvo.Iwo anowirirana masaini anoyerwa neakasiyana masensor, uye ipapo iyo yakawanda-sensor information fusion tekinoroji inoshandiswa kunzwa iyo mamiriro ekugadzirisa ruzivo, kuitira kupa mutongi ruzivo rwechokwadi uye rwakavimbika rwakakwana uye nekuvandudza kutonga kwechokwadi.
Nekuwedzera kuri kuda kwekumhanyisa uye chaiyo-nguva yehurongwa hwekugadzirisa ruzivo, uye nekuvandudzwa kwemasekete makuru akabatanidzwa, kune akasiyana machipisi DSP akatsaurirwa kune chaiyo-nguva yedhijitari chiratidzo chekugadzirisa Kana ichienzaniswa neyakajairwa-chinangwa microprocessors, hunhu hwayo hukuru. ari maviri: mazhinji maDSP machipi anotora Harvard chimiro, ndiko kuti, nzvimbo yekuchengetedza yemirairo yechirongwa uye data yakaparadzaniswa, uye imwe neimwe ine kero yayo uye data bhasi, izvo zvinoita kuti mirairo yekugadzirisa uye data riitwe panguva imwe chete, iyo inovandudza zvakanyanya kushanda kwekugadzirisa;Kana yakajairika-chinangwa microprocessor ichiita rairo, inoda akati wandei kuraira kutenderera kuti ipedze.Iyo DSP chip inotora pombi tekinoroji.Kunyange zvazvo nguva yekuitwa yerairo imwe neimwe ichiri miitiro yemirairo yakawanda, nekuda kwekuyerera kwemirairo, inotorwa pamwe chete, nguva yekupedzisira yekuraira yega yega inopedzwa muchikamu chimwe chekuraira.
Munhamba yekudzora sisitimu, iyo yedhijitari chiratidzo processor inopedzisa mabasa ekutora data, chizvarwa chetrajectory, kutonga sarudzo sarudzo uye chaiyo-nguva kutonga.
3 mhedziso kutanga kubva pane zvinodiwa zvebhasiketi chaiyo machining, pepa iri rinotora workpiece uye NC system seyakabatana yakazara kuburikidza neakawanda-sensor ruzivo rwekusanganisa tekinoroji, inofunga maitiro ekuvandudza basket machining iko, uye inoisa pamberi pekutonga zano rebhasiketi Performance NC system. zvichibva pane yakavhurika chimiro.Iyi nzira yakakoshawo pakutonga kwemamwe miviri inofamba.
