I-CNC machining, noma i-Computer Numerical Control machining, inqubo yokukhiqiza eyinguquko esebenzisa isofthiwe yekhompyutha ukulawula amathuluzi omshini. Lobu buchwepheshe buguqule indlela imikhiqizo eklanywa futhi ekhiqizwa ngayo, okuvumela ukunemba okuphezulu nokusebenza kahle ekukhiqizeni izingxenye eziyinkimbinkimbi kuzo zonke izimboni ezihlukahlukene. Lesi sihloko sizodingida ubunkimbinkimbi bemishini ye-CNC, izinqubo zayo, izinzuzo, izinhlelo zokusebenza, nokunye okuningi.

 

Ukuqonda CNC Machining

I-CNC machining iyinqubo yokukhiqiza ekhiphayo esusa impahla ebhulokhini eliqinile (ucezu lokusebenza) ukuze kwakheke umumo oyifunayo. Indlela incike kuhlelo lwekhompiyutha oluhlelwe ngaphambilini ukuze lunqume ukuhamba kwemishini namathuluzi. Imishini ye-CNC ingasebenza ngezinto ezihlukahlukene, okuhlanganisa izinsimbi, amapulasitiki, ukhuni, nezinhlanganisela.

 

Isebenza kanjani i-CNC Machining

Inqubo yemishini ye-CNC ingahlukaniswa ngezinyathelo ezimbalwa ezibalulekile:

1. Ukuklama Imodeli Ye-CAD: Isinyathelo sokuqala sihlanganisa ukudala imodeli enemininingwane ye-2D noma ye-3D yengxenye kusetshenziswa isofthiwe ye-Computer-Aided Design (CAD). Izinhlelo ezidumile ze-CAD zifaka i-AutoCAD neSolidWorks.

2. Ukuguqulela ku-G-Code: Uma imodeli ye-CAD isilungile, kufanele iguqulelwe ibe ifomethi imishini ye-CNC engayiqonda, ngokuvamile i-G-code. Le khodi iqukethe iziqondiso zomshini zokuthi unyakaze futhi usebenze kanjani.

3. Ukusetha Umshini: U-opharetha ulungiselela umshini we-CNC ngokukhetha amathuluzi afanele futhi afake ucezu lokusebenza ngokuphephile.

4. Ukwenza Inqubo Yomshini: Umshini we-CNC ulandela ikhodi ye-G ukuze wenze imisebenzi yokusika. Amathuluzi angase ahambisane nezimbazo eziningi (imvamisa ezi-3 noma ezi-5) ukuze kuzuzwe izimo eziyinkimbinkimbi.

5. Ukulawulwa Kwekhwalithi: Ngemva komshini, ingxenye eqediwe iyahlolwa ukuze kuqinisekiswe ukuthi ihlangabezana nokubekezelelana okucacisiwe kanye namazinga ekhwalithi.

 

Izinhlobo zemishini ye-CNC

Imishini ye-CNC iza ngezinhlobo ezahlukene, ngayinye ilungele izinhlelo zokusebenza ezithile:

- Izigayi ze-CNC: Isetshenziselwa imisebenzi yokugaya lapho impahla isuswa kucezu lokusebenza. - I-CNC Lathes: Ilungele ukuguqula imisebenzi lapho ucezu lokusebenza luzungeza ithuluzi lokusika elimile.
