Nekuda kweiyo yakanyanya kurongeka zvinodikanwa zvezvigadzirwa zvakagadziriswa, zvinhu zvinofanirwa kutariswa kana hurongwa ndezvi:
Kutanga, funga nezvekugadzirisa kutevedzana kwezvikamu:
1. Dhonza maburi kutanga uye wozoisa magumo (izvi ndezvekudzivirira shrinkage yezvinhu panguva yekuchera);
2. Kutendeuka kwakashata kutanga, uye kutendeuka kwakanaka (izvi ndezvechokwadi chechokwadi chezvikamu);
3. Gadzira zvikamu zvine kushivirira kukuru kutanga uye gadzira zvikamu zvine kushivirira kudiki kwekupedzisira (izvi ndezvekuona kuti nzvimbo yediki yekushivirira zviyero haina kukweshwa uye kudzivirira zvikamu kubva pakuremara).
Zvinoenderana nekuoma kwezvinhu, sarudza inonzwisisika yekutenderera kumhanya, huwandu hwekudya uye kudzika kwekucheka:
1. Sarudza kumhanya kukuru, chiyero chekudya chakanyanya uye kudzika kukuru kwekuchekwa senge kabhoni simbi zvinhu. Somuenzaniso: 1Gr11, sarudza S1600, F0.2, kudzika kwekucheka 2mm;
2. Kune carbide ine simende, sarudza yakaderera kumhanya, yakaderera chiyero chekudya, uye kudzika kudiki kwekucheka. Somuenzaniso: GH4033, sarudza S800, F0.08, kudzika kwekucheka 0.5mm;
3. Kune titanium alloy, sarudza yakaderera kasi, yakakwira yekudyisa mwero uye kudzika kudiki kwekucheka. Semuenzaniso: Ti6, sarudza S400, F0.2, kudzika kwekucheka 0.3mm. Tora kugadziridzwa kwechimwe chikamu semuenzaniso: zvinhu iK414, inova yakawedzera-yakaoma zvinhu. Mushure mekuedzwa kwakawanda, S360, F0.1, uye kudzika kwakadzika kwe0.2 zvakazosarudzwa chikamu chakakodzera chisati chagadziriswa.
Unyanzvi hwekugadzira banga
Chigadziro chekushandisa chakakamurwa kuita chishandiso chekumisikidza chiridzwa uye yakananga maturusi kuseta. Maturusi ezvishandiso ataurwa pazasi ndiwo akananga maturusi marongero.
Xinfa CNC zvishandiso zvine hunhu hwemhando yakanaka uye mutengo wakaderera. Kuti uwane ruzivo, ndapota shanya:

Common tool setters
Kutanga sarudza nzvimbo yepakati yerudyi rwekumagumo chiso chechikamu sechokushandisa calibration point woiisa sezero point. Mushure mekunge mudziyo wemuchina wadzokera kune kwawakatangira, chishandiso chega chega chinoda kushandiswa chinoyerwa nepakati pechekumucheto kwerudyi rwechikamu se zero point; kana chishandiso chabata kumeso kwekurudyi, pinda Z0 uye tinya kuyerwa. Iko kuyerwa kukosha kunozorekodhwa otomatiki mumudziyo wekubvisa kukosha, zvinoreva kuti iyo Z-axis chishandiso kurongeka kwakaringana.
X chishandiso kuseta ndeyekuyedza kucheka. Shandisa chishandiso kushandura denderedzwa rekunze rechikamu kuti rive diki. Edza kukosha kwedenderedzwa rekunze kuti rishandurwe (semuenzaniso, X iri 20mm) uye isa X20. Dzvanya Measure. Chishandiso chekubvisa kukosha chinozonyora otomatiki kukosha kwakayerwa. Iyo axis inofananidzwa zvakare;
Iyi nzira yekumisikidza chishandiso haizoshandura kukosha kwechishandiso kunyangwe mudziyo wemuchina wakadzimwa uye wotangwazve. Inogona kushandiswa kugadzira zvikamu zvakafanana muhuwandu hukuru kwenguva yakareba, uye hapana chikonzero chekugadzirisa zvakare chishandiso mushure mekuvhara lathe.
Debugging Tips
Mushure mekunge zvikamu zvarongwa uye banga raiswa, kucheka kwekuyedza uye kugadzirisa kunodiwa kudzivirira kukanganisa kwechirongwa uye zvikanganiso zvekumisikidza zvishandiso kubva pakukonzera kudhumhana kwemuchina.
Iwe unofanirwa kutanga waita isina basa sitiroko simulation kugadzirisa, wakatarisana nechishandiso mune yekuronga sisitimu yemuchina wemuchina uye fambisa chikamu chose kurudyi ne2 kusvika ku3 nguva dzehurefu hwechikamu; wobva watanga simulation processing. Mushure mekugadzirisa kuenzanisira kwapera, simbisa kuti chirongwa uye chekugadzirisa chekushandisa chakarurama, uye wobva watanga kugadzirisa chikamu. Kugadziridza, mushure mekunge chikamu chekutanga chagadziriswa, tanga wazviongorora wega kuti usimbise kuti inokodzera, uye wozowana kuongororwa kwenguva yakazara. Chete mushure mekunge kuongororwa kwenguva yakazara kunosimbisa kuti inokodzera, debugging inopedzwa.
Kupedzisa kugadzirisa kwezvikamu
Mushure mokunge chidimbu chekutanga chaedzwa-chekwa, zvikamu zvichagadzirwa mumabheti. Zvisinei, kukodzera kwechidimbu chekutanga hazvirevi kuti chikamu chose chezvikamu chichave chakakodzera, nokuti panguva yekugadzirisa, chigadziro chichapfeka nekuda kwezvinhu zvakasiyana-siyana zvekugadzirisa. Kana chimbo chacho chiri chinyoro, chipfeko chinopfeka chichava chiduku. Kana iyo yekugadzira zvinhu yakaoma, chishandiso chinopfeka nekukurumidza. Naizvozvo, panguva yekugadziriswa, zvinodikanwa kuti utarise nguva nenguva uye kuwedzera uye kuderedza kukosha kwechishandiso chemuripo panguva yakakodzera kuti uve nechokwadi chekuti zvikamu zvinokodzera.
Tora chikamu chakambogadzirwa semuenzaniso
Iyo yekugadzirisa zvinhu ndeye K414, uye iyo yakazara yekugadzirisa kureba ndeye 180mm. Nekuti zvinhu zvacho zvakaoma, chishandiso chinopfeka nekukurumidza panguva yekugadzira. Kubva panotangira kusvika kumagumo, pachava nekagero kadiki ke10 ~ 20mm nekuda kwekupfeka kwemidziyo. Nokudaro, tinofanira kuwedzera 10 kune purogiramu. ~ 20mm, kuitira kuti uve nechokwadi chekuti zvikamu zvinokodzera.
Nheyo dzekutanga dzekugadzirisa: hutsinye kugadzirisa kutanga, bvisa yakawandisa zvinhu kubva kune workpiece, uye wozopedzisa kugadzirisa; vibration inofanira kudziviswa panguva yekugadzirisa; kuderera kwekushisa panguva yekugadzirisa workpiece kunofanira kudziviswa. Pane zvikonzero zvakawanda zvekuzununguka, izvo zvingave zvichikonzerwa nemutoro wakawandisa; Inogona kunge iri resonance yemuchina wemuchina uye workpiece, kana kungave kushaikwa kwekuomarara kwechishandiso chemuchina, kana kuti zvinogona kukonzerwa nekugomara kwechishandiso. Tinogona kuderedza vibration kuburikidza nenzira dzinotevera; kuderedza kuchinjika kudyisa huwandu uye kudzika kwekugadzirisa, uye tarisa iyo workpiece yekuisa. Tarisa uone kana chisungiso chakachengeteka. Kuwedzera kumhanya kwechishandiso uye kudzikisa kumhanya kunogona kuderedza resonance. Mukuwedzera, tarisa kana zvakakosha kutsiva chishandiso neitsva.
Mazano ekudzivirira kudhumhana kwemidziyo yemuchina
Kudhumhana kwechishandiso chemuchina kuchakonzera kukuvadzwa kukuru mukurongeka kwechishandiso chemuchina, uye maitiro acho achave akasiyana pamhando dzakasiyana dzematurusi emuchina. Kazhinji kutaura, kukanganisa kuchave kwakakura pamaturusi emuchina asina kusimba mukuoma. Naizvozvo, kune yakakwirira-chaiyo CNC lathes, kudhumhana kunofanirwa kubviswa. Chero bedzi mushandisi akangwarira uye aine dzimwe nzira dzekupokana, kudhumhana kunogona kudzivirirwa zvachose uye kudzivirirwa.
Zvikonzero zvikuru zvekudhumhana:
☑ Kureba nekureba kwechombo zvakapinzwa zvisizvo;
☑ Kupinda kwakashata kwezviyero zvechishandiso uye zvimwe zvine hukama geometric zviyero, pamwe nekukanganisa munzvimbo yekutanga yebasa rekushanda;
☑ Iyo workpiece yekubatanidza sisitimu yemuchina wemuchina yakasetwa zvisizvo, kana muchina zero point inogadzikiswa patsva panguva yekugadzira uye shanduko. Kudhumhana kwechishandiso chemuchina kunowanzoitika panguva yekukurumidza kufamba kwechishandiso chemuchina. Kudhumhana kunoitika panguva ino ndiko zvakare kunokuvadza zvakanyanya uye kunofanira kudzivirirwa zvachose. Naizvozvo, mushandisi anofanirwa kutarisisa kune yekutanga nhanho yemuchina wekushandisa chirongwa uye kana chishandiso chemuchina chiri kuchinja chishandiso. Panguva ino, kana chikanganiso chekugadzirisa chirongwa chikaitika uye dhayamita uye kureba kwechishandiso zvakapindwa zvisiri izvo, kudhumhana kuchaitika nyore. Pakupera kwechirongwa, kana kudzokorodza kutevedzana kweCNC axis kwakashata, kudhumhana kunogona kuitikawo.
Kuti udzivise kudhumhana kuri pamusoro, mushandisi anofanira kupa kutamba kwakazara kumabasa epfungwa shanu kana achishanda muchina chishandiso. Tarisa uone kana paine kufamba kusiri kujairika kwechishandiso chemuchina, kana twumoto, kana paine ruzha uye ruzha rusina kujairika, kana paine mavibrations, uye kana paine hwema hwakatsva. Kana kukanganisa kukawanikwa, chirongwa chinofanira kumiswa nekukasira. Chishandiso chemuchina chinogona kuramba chichishanda chete mushure mekunge dambudziko remuchina ragadziriswa.
