CNC imashini ikora gahunda yo gutangiza gahunda, niba utabizi, ngwino wige

1. guhagarika itegeko

G04X (U) _ / P_ bivuga igikoresho cyo guhagarika igihe (ibiryo birahagarara, spindle ntabwo ihagarara), kandi agaciro nyuma ya adresse P cyangwa X nigihe cyo kuruhuka. Agaciro nyuma

Kurugero, G04X2.0; cyangwa G04X2000; hagarara amasegonda 2

G04P2000;

Nyamara, muburyo bumwe bwo gutunganya sisitemu yo gutunganya (nka G82, G88 na G89), kugirango tumenye neza neza neza umwobo, hari igihe cyo guhagarara igihe igikoresho gitunganyiriza munsi yumwobo. Muri iki gihe, birashobora kugaragazwa gusa na aderesi P. Niba Aderesi X yerekana ko sisitemu yo kugenzura ifata X ko ari X-axis ihuza agaciro kandi ikayishyira mu bikorwa.

Kurugero, G82X100.0Y100.0Z-20.0R5.0F200P2000; umwitozo (100.0, 100.0) munsi yumwobo hanyuma uhagarare amasegonda 2

G82X100.0Y100.0Z-20.0R5.0F200X2.0; gucukura (2.0, 100.0) kugeza munsi yumwobo utaruhuka.

2. Itandukaniro n'amasano hagati ya M00, M01, M02 na M30

M00 ni amabwiriza yo kuruhuka atagabanijwe kuri gahunda. Iyo porogaramu irangiye, ibiryo birahagarara na spindle irahagarara. Kugirango utangire porogaramu, ugomba kubanza gusubira muri leta ya JOG, kanda CW (kuzunguruka imbere) kugirango utangire kuzunguruka, hanyuma usubire muri leta ya AUTO, kanda urufunguzo rwa START kugirango utangire gahunda.

M01 ni gahunda yo guhitamo guhagarika amabwiriza. Mbere yuko porogaramu ikorwa, urufunguzo rwa OPSTOP kurupapuro rugenzura rugomba gufungura. Ingaruka nyuma yo gukora ni kimwe na M00. Porogaramu igomba gutangira nkuko byavuzwe haruguru.

M00 na M01 bikoreshwa kenshi mugusuzuma cyangwa gukuramo chip ibipimo byakazi mugihe cyo gutunganya.

M02 ninyigisho nyamukuru yo kurangiza amabwiriza. Iyo iri tegeko ryakozwe, ibiryo birahagarara, spindle irahagarara, na coolant irazimya. Ariko porogaramu indanga ihagarara kurangiza gahunda.

M30 ni gahunda nyamukuru yo kurangiza itegeko. Imikorere ni kimwe na M02, itandukaniro nuko indanga isubira muri progaramu ya progaramu ya progaramu, utitaye ko hari ibindi bice bya porogaramu nyuma ya M30.

3. Aderesi D na H zifite ibisobanuro bimwe

Ibikoresho byo kwishyura ibikoresho D na H bifite imikorere imwe kandi birashobora guhinduka uko bishakiye. Bombi bahagarariye izina rya aderesi y’igitabo cy’indishyi muri sisitemu ya CNC, ariko agaciro k’indishyi kihariye kagenwa na aderesi y’indishyi ziri inyuma yabo. Nyamara, mu bigo bitunganya imashini, kugirango hirindwe amakosa, muri rusange hateganijwe ko H ari adresse yuburebure bwibikoresho, nimero yindishyi kuva kuri 1 kugeza kuri 20, D nigikoresho cya radiyo indishyi, numero yindishyi itangirira kuri No . 21 (ikinyamakuru igikoresho gifite ibikoresho 20).

4. Itegeko ry'indorerwamo

Amashusho yo gutunganya amashusho M21, M22, M23. Iyo X-axis cyangwa Y-axis byonyine byerekanwe, gukata gukurikiranye (kuzamuka no gukata-gusya), icyerekezo cyo kwishyura ibikoresho, hamwe na arc interpolation kuyobora bizaba bitandukanye na gahunda nyirizina, nkuko bigaragara ku gishushanyo cya 1. Iyo X -axis na Y-axis byerekanwe mugihe kimwe, ibikoresho byo kugaburira ibikoresho, icyerekezo cyo kwishyura ibikoresho, hamwe na arc interpolation kuyobora ntigihinduka.

Icyitonderwa: Nyuma yo gukoresha indorerwamo, ugomba gukoresha M23 kugirango uyihagarike kugirango wirinde kugira ingaruka kuri gahunda zikurikira. Muburyo bwa G90, mugihe ukoresheje ishusho yindorerwamo cyangwa guhagarika itegeko, ugomba gusubira mwinkomoko yumurimo uhuza sisitemu mbere yuko ikoreshwa. Bitabaye ibyo, sisitemu ya CNC ntishobora kubara inzira ikurikiraho, kandi igikoresho kidasanzwe kizabaho. Muri iki gihe, intoki zigaruka zigomba gukorwa kugirango ikibazo gikemuke. Kuzunguruka kuzunguruka ntabwo bihinduka hamwe nindorerwamo ishusho.

Igishushanyo 1: Indishyi zikoreshwa, imbere no guhindura impinduka mugihe cyo kwerekana

5. Arc interpolation itegeko

G02 ni interpolation yisaha, G03 ni interpolation yisaha. Mu ndege ya XY, imiterere niyi ikurikira: G02 / G03X_Y_I_K_F_ cyangwa G02 / G

03X_Y_R_F_, aho

Iyo gukata arc, nyamuneka menya ko iyo q≤180 °, R nigiciro cyiza; iyo q> 180 °, R ni agaciro keza; I na K birashobora kandi gutomorwa hamwe na R. Iyo byombi byerekanwe mugihe kimwe, itegeko R rifata umwanya wambere, kandi I, K ntagaciro; R ntishobora gukora uruziga rwuzuye, kandi gukata uruziga rwuzuye birashobora gutegurwa gusa na I, J, na K, kuko hariho uruziga rutabarika rufite radiyo imwe inyura kumurongo umwe, nkuko bigaragara ku gishushanyo cya 2.

Igishushanyo 2 Uruziga runyura mu ngingo imwe

Iyo I na K ari zeru, zirashobora gusibwa; utitaye kuburyo bwa G90 cyangwa G91, I, J, na K byateguwe ukurikije guhuza ibikorwa; mugihe arc interpolation, amabwiriza yo kwishyura ibikoresho G41 / G42 ntashobora gukoreshwa.

6． Ibyiza n'ibibi hagati ya G92 na G54 ~ G59

G54 ~ G59 ni sisitemu yo guhuza ibikorwa yashyizweho mbere yo kuyitunganya, naho G92 niyo sisitemu yo guhuza ibikorwa muri gahunda. Nyuma yo gukoresha G54 ~ G59, nta mpamvu yo kongera gukoresha G92, bitabaye ibyo G54 ~ G59 izasimburwa kandi igomba kwirindwa, nkuko bigaragara mu mbonerahamwe ya 1.

Imbonerahamwe 1 Itandukaniro riri hagati ya G92 na sisitemu yo guhuza ibikorwa

Icyitonderwa: (1) G92 imaze gukoreshwa mugushiraho sisitemu yo guhuza ibikorwa, ukoresheje G54 ~ G59 na none nta ngaruka bizagira keretse iyo sisitemu ishizwemo ingufu hanyuma igatangira, cyangwa G92 ikoreshwa mugushiraho sisitemu nshya ikenewe yo guhuza ibikorwa. (2) Nyuma ya porogaramu ukoresheje G92 irangiye, niba igikoresho cyimashini kidasubiye?

Niba inkomoko yashyizweho na 羾 92 yongeye gutangira, umwanya wibikoresho byimashini bizahinduka ibihangano bishya bihuza inkomoko, bikunze guhura nimpanuka. Kubwibyo, nizere ko abasomyi bazayikoresha bitonze.

7. Tegura ibikoresho bihindura subroutine.

Ku kigo gikora imashini, guhindura ibikoresho byanze bikunze. Nyamara, igikoresho cyimashini gifite igikoresho gihamye cyo guhindura iyo kiva muruganda. Niba itari kumwanya wigikoresho cyo guhindura, igikoresho ntigishobora guhinduka. Byongeye kandi, mbere yo guhindura ibikoresho, indishyi yibikoresho hamwe ninzinguzingo bigomba guhagarikwa, spindle irahagarara, na coolant ikazimya. Hariho ibintu byinshi. Niba ibi bintu bigomba gukurikizwa mbere yuko buri gikoresho cyifashishwa gihinduka, ntabwo kizaba gikunze kwibeshya gusa ariko nanone ntigikora. Kubwibyo, turashobora gukusanya porogaramu yo guhindura ibikoresho kugirango tuyibike kandi tuyikoreshe muri leta ya DI. Hamagara M98 irashobora kurangiza ibikorwa byo guhindura ibikoresho muburyo bumwe.

Dufashe urugero rwimashini ya PMC-10V20 nkurugero, gahunda niyi ikurikira:

O2002; (izina rya gahunda)

G80G40G49; (Hagarika ukwezi gutunganijwe hamwe n'indishyi z'ibikoresho)

M05; (Spindle ihagarara)

M09; (coolant ifunga)

G91G30Z0; (Z axis igaruka ku nkomoko ya kabiri, aricyo gikoresho cyo guhindura)

M06; (Guhindura ibikoresho)

M99; (Iherezo rya subroutine)

Mugihe ukeneye guhindura igikoresho, ugomba gusa kwandika "T5M98P2002 ″ muri leta ya MDI kugirango usimbuze igikoresho gikenewe T5, bityo wirinde amakosa menshi adakenewe. Abasomyi barashobora gukusanya ibikoresho bihuye bihindura subroutines ukurikije ibiranga ibikoresho byabo byimashini.

8. ibindi

Umubare w'urutonde rwa porogaramu, uhagarariwe na aderesi N. Mubisanzwe, igikoresho cya CNC ubwacyo gifite umwanya muto wo kwibuka (64K). Kugirango uzigame umwanya wabitswe, porogaramu ikurikiranye nimero ikurikirana. N yerekana gusa ikirango cya porogaramu igice, gishobora koroshya gushakisha no guhindura gahunda. Nta ngaruka igira mubikorwa byo gutunganya. Umubare ukurikirana urashobora kwiyongera cyangwa kugabanuka, kandi gukomeza indangagaciro ntibisabwa. Ariko, ntishobora gusibwa mugihe ukoresheje amabwiriza amwe, gusimbuka amabwiriza, guhamagara subroutines hamwe namabwiriza yindorerwamo.

9. Mu gice kimwe cya porogaramu, kubwinyigisho imwe (inyuguti imwe ya adresse) cyangwa itsinda rimwe ryamabwiriza, imwe igaragara nyuma izatangira gukurikizwa.

Kurugero, gahunda yo guhindura ibikoresho, T2M06T3; asimbuye T3 mu mwanya wa T2;

G01G00X50.0Y30.0F200; G00 irakorwa (nubwo hari agaciro F, G01 ntabwo ikorwa).

Amabwiriza yinyandiko zitari mumatsinda amwe agira ingaruka zimwe niba zakozwe mugice kimwe cya gahunda muguhana urukurikirane.

G90G54G00X0Y0Z100.0;

G00G90G54X0Y0Z100.0;

Ibintu byose byavuzwe haruguru byarakozwe kandi byanyujijwe kuri santeri ya PMC-10V20 (FANUCSYSTEM). Mubikorwa bifatika, gusa birasobanutse byimbitse kumikoreshereze namategeko yo gutangiza amabwiriza atandukanye.

Ibikoresho bya Xinfa CNC bifite ibiranga ubuziranenge bwiza nigiciro gito. Ushaka ibisobanuro birambuye, nyamuneka sura:
