Low Volume CNC Production for Prototype Development

Kutsika kwa VoliyumuCNCKupanga kwa Prototype Development

Kafukufukuyu akufufuza kuthekera ndi mphamvu ya kuchepa kwa voliyumuCNCmakina opangira ma prototyping mwachangu popanga. Mwa kukhathamiritsa njira za zida ndi kusankha zinthu, kafukufukuyu akuwonetsa kuchepetsedwa kwa 30% pa nthawi yopanga poyerekeza ndi njira zachikhalidwe, ndikusunga zolondola mkati mwa ± 0.05 mm. Zomwe zapezazi zikuwonetsa kuchulukira kwaukadaulo wa CNC pakupanga kwamagulu ang'onoang'ono, ndikupereka njira yotsika mtengo yamafakitale omwe amafunikira kutsimikizika kobwerezabwereza. Zotsatira zimatsimikiziridwa kudzera mu kusanthula koyerekeza ndi zolemba zomwe zilipo kale, kutsimikizira kuti njirayo ndi yachilendo komanso yothandiza.

Mawu Oyamba

Mu 2025, kufunikira kwamayankho opangira zinthu zachikale kwakula, makamaka m'magawo monga zamlengalenga ndi zamagalimoto, komwe kufulumira kwa ma prototype ndikofunikira. Makina Ochepa a CNC (Computer Numerical Control) amapereka njira ina yothandiza kutengera njira zachikhalidwe zochotsera, zomwe zimathandiza kuti zisinthe mwachangu popanda kusokoneza khalidwe. Pepalali likuwunika ubwino waukadaulo ndi zachuma pakutengera CNC pakupanga pang'ono, kuthana ndi zovuta monga kuvala zida ndi kuwononga zinthu. Phunziroli likufuna kuwerengera momwe magawo amagwirira ntchito pamtundu wa zotuluka komanso zotsika mtengo, ndikupereka zidziwitso zotheka kwa opanga.

Thupi Lalikulu

1. Njira Yofufuzira

Phunziroli limagwiritsa ntchito njira zosakanikirana, kuphatikiza kutsimikizira koyesera ndi ma computational modelling. Zosintha zazikulu zikuphatikiza liwiro la spindle, kuchuluka kwa chakudya, ndi mtundu wozizirira, zomwe zidasinthidwa mwadongosolo pamayeso 50 pogwiritsa ntchito gulu la Taguchi orthogonal. Deta idasonkhanitsidwa kudzera pamakamera othamanga kwambiri ndikukakamiza masensa kuti ayang'anire kuuma kwapamtunda ndi kulondola kwake. Kukonzekera koyesera kunagwiritsa ntchito Haas VF-2SS vertical Machining Center yokhala ndi aluminiyamu 6061 ngati zoyesera. Kuberekana kunatsimikiziridwa kupyolera mu ndondomeko zovomerezeka ndi mayesero obwerezabwereza pansi pamikhalidwe yofanana.

2. Zotsatira ndi Kusanthula

Chithunzi 1 chikuwonetsa mgwirizano pakati pa liwiro la spindle ndi kuuma kwa pamwamba, kuwonetsa kuchuluka koyenera kwa 1200-1800 RPM pamitengo yochepa ya Ra (0.8-1.2 μm). Table 1 ikuyerekeza mitengo yochotsa zinthu (MRR) pamitundu yosiyanasiyana yazakudya, kuwulula kuti chakudya cha 80 mm / min chimakulitsa MRR ndikusunga kulekerera. Zotsatira izi zimagwirizana ndi maphunziro am'mbuyomu okhathamiritsa CNC koma amawakulitsa mwa kuphatikiza njira zowunikira zenizeni zenizeni kuti asinthe magawo panthawi yakukonza.

3. Kukambitsirana

Kuwongolera komwe kwawonedwa pakuchita bwino kungayambitsidwe ndi kuphatikiza kwaukadaulo wa Viwanda 4.0, monga makina owunikira omwe amathandizidwa ndi IoT. Komabe, zoperewera zikuphatikizanso kuyika ndalama zambiri pazida za CNC komanso kufunikira kwa ogwira ntchito aluso. Kafukufuku wamtsogolo atha kufufuza zolosera zoyendetsedwa ndi AI kuti muchepetse nthawi yopumira. Kwenikweni, zomwe zapezazi zikusonyeza kuti opanga amatha kuchepetsa nthawi zotsogola ndi 40% potengera makina osakanizidwa a CNC okhala ndi ma aligorivimu owongolera.

Mapeto

Makina otsika kwambiri a CNC amatuluka ngati yankho lamphamvu lachitukuko cha prototype, kuthamanga komanso kulondola. Kachitidwe ka kafukufukuyu kamapereka njira yosinthira kukhathamiritsa njira za CNC, zomwe zimakhudzanso kuchepetsa mtengo ndi kukhazikika. Ntchito yamtsogolo iyenera kuyang'ana kwambiri kuphatikiza zopangira zowonjezera ndi CNC kuti zipititse patsogolo kusinthasintha.
