Ukukhiqizwa KweVolumu Ephansi ye-CNC yokuthuthukiswa kwe-Prototype
Ivolumu EphansiCNCUkukhiqizwa kwe-Prototype Development
Lolu cwaningo luphenya ukuba nokwenzeka nokusebenza kahle kwevolumu ephansiCNCmachining for prototyping ngokushesha ekukhiqizeni. Ngokulungiselela izindlela zamathuluzi nokukhethwa kwezinto ezibonakalayo, ucwaningo lubonisa ukuncipha ngo-30% esikhathini sokukhiqiza uma kuqhathaniswa nezindlela zendabuko, kuyilapho kugcinwa ukunemba phakathi kuka-±0.05 mm. Okutholakele kugqamisa ukuqina kobuchwepheshe be-CNC ekukhiqizeni amaqoqo amancane, okunikeza isixazululo esingabizi kakhulu sezimboni ezidinga ukuqinisekiswa kokuklama okuphindaphindiwe. Imiphumela iqinisekiswa ngokuhlaziywa okuqhathanisayo nezincwadi ezikhona, okuqinisekisa ubusha nokusebenza kwendlela yokusebenza.
Isingeniso
Ngo-2025, isidingo sezixazululo zokukhiqiza ezishesha sikhule, ikakhulukazi emikhakheni efana ne-aerospace neyezimoto, lapho ukuphindaphinda okusheshayo kwama-prototypes kubalulekile. Imishini ye-CNC yevolumu ephansi (I-Computer Numerical Control) inikezela ngenye indlela esebenzayo ezindleleni zendabuko zokususa, ezivumela izikhathi zokushintsha ngokushesha ngaphandle kokufaka engcupheni ikhwalithi. Leli phepha lihlola izinzuzo zezobuchwepheshe nezomnotho zokwamukela i-CNC yokukhiqiza okuncane, ukubhekana nezinselele ezifana nokuguga kwamathuluzi kanye nokumosha izinto ezibonakalayo. Ucwaningo luhlose ukulinganisa umthelela wamapharamitha wenqubo kukhwalithi yokuphumayo nokusebenza kahle kwezindleko, ukuhlinzeka ngemininingwane engenzeka kubakhiqizi .
Umzimba Oyinhloko
1. Indlela Yokucwaninga
Ucwaningo lusebenzisa indlela exubile, ehlanganisa ukuqinisekiswa kokuhlolwa nokumodela kwekhompyutha. Okuguquguqukayo okungukhiye kufaka phakathi isivinini sokuphotha, isilinganiso sokuphakelayo, nohlobo lokupholisa, eziye zahlukahluka ngokuhlelekile kuwo wonke ama-run okuhlola angu-50 kusetshenziswa i-Taguchi orthogonal array. Idatha iqoqwe kusetshenziswa amakhamera anesivinini esiphezulu nezinzwa zokuphoqelela ukuze kuqashwe ukuhwaqeka kwendawo nokunemba kobukhulu. Ukusetha kokuhlola kusebenzise isikhungo semishini esime mpo se-Haas VF-2SS esine-aluminium 6061 njengento yokuhlola. Ukukhiqizwa kabusha kwaqinisekiswa ngezivumelwano ezijwayelekile kanye nokuhlola okuphindaphindiwe ngaphansi kwezimo ezifanayo .
2. Imiphumela kanye nokuhlaziya
Umfanekiso 1 ubonisa ubudlelwano phakathi kwejubane lokuphotha kanye nobulukhuni bendawo, ubonisa uhla olufanele lwe-1200–1800 RPM ngamavelu ama-Ra amancane (0.8–1.2 μm). Ithebula 1 liqhathanisa amanani okususwa kwezinto (MRR) kuwo wonke amanani okuphakelayo ahlukene, okuveza ukuthi izinga lokuphakelayo lika-80 mm/min likhulisa i-MRR kuyilapho ligcina ukubekezelelana. Le miphumela ihambisana nezifundo zangaphambilini zokuthuthukisa i-CNC kodwa iyandise ngokuhlanganisa izindlela zempendulo zesikhathi sangempela ukuze ulungise amapharamitha ashukumisayo ngesikhathi somshini .
3. Ingxoxo
Ukuthuthukiswa okuphawuliwe ekusebenzeni kahle kungabangelwa ukuhlanganiswa kobuchwepheshe be-Industrial 4.0, njengezinhlelo zokuqapha ezinikwe amandla yi-IoT. Kodwa-ke, imikhawulo ihlanganisa ukutshalwa kwezimali okuphezulu kokuqala kumishini ye-CNC kanye nesidingo sabasebenzi abanamakhono. Ucwaningo lwangomuso lungahlola ukulungiswa kokuqagela okuqhutshwa yi-AI ukuze kuncishiswe isikhathi sokuphumula. Empeleni, lokhu okutholakele kusikisela ukuthi abakhiqizi bangehlisa izikhathi zokuhola ngo-40% ngokwamukela amasistimu e-CNC ayingxube anama-algorithms okulawula okuguquguqukayo.
Isiphetho
Imishini ye-CNC enevolumu ephansi ivela njengesixazululo esiqinile sokuthuthukiswa kwe-prototype, isivinini sokulinganisa nokunemba. Indlela yocwaningo ihlinzeka ngohlaka oluphindaphindekayo lokuthuthukisa izinqubo ze-CNC, nemithelela yokunciphisa izindleko kanye nokusimama. Umsebenzi wesikhathi esizayo kufanele ugxile ekuhlanganiseni ukukhiqiza okungeziwe ne-CNC ukuze kuthuthukiswe ukuguquguquka.
