Ungasikhetha kanjani isisekelo se-CNC Machining?

Lapho i-workpiece ifakwe emnyani, ingaphezulu lokuthola isikhundla esilinganiselwe se-workpiece kuthuluzi lomshini futhi ithuluzi libizwa ngesikhundla. Isisekelo sesikhundla esisetshenziswa kwinqubo yokuqala yindawo engavinjelwe ye-rough, ebizwa nge-raving datum. Isisekelo sesikhundla esisetshenziswa kwinqubo elandelayo machineng yinto emnyameni, ebizwa ngokuthi i-disiching datum.

1. Isimiso sokukhetha se-Datum Datum

1) Ukukhetha kwe-rautir dum kufanele kube lula ukuthola, ukubopha imishini ye-CNC, futhi kwenze isakhiwo sokulungiswa kalula.

2) Uma kudingekile okokuqala ukuqinisekisa ukunemba kwesikhashana phakathi kwe-Workiepe CNC Machching Surface kanye ne-non-machining ceichbal, kufanele kube yimishini engeyona imishini njenge-datum enolaka.

3) Ukuqinisekisa ukuthi isibonelelo esibi sezinto ezithile ezibalulekile sincane futhi sifana, lo ndawo kufanele ikhethwe njengeyisisekelo esinzima.

4) Ukuze wenze imvume ye-CNC Maching ye-CNC yezindawo eziningi ezingenalutho umfaniswano ongenalutho, isisekelo esinzima kufanele sikhethe indawo enzima engahlukanisa ngokulinganayo iphutha lesikhundla sendawo ekhethiwe.

I-5) indawo evuthayo ye-datum kufanele ibe bushelelezi, ngaphandle kweziphambeko zesango, i-riser noma emaphethelweni ezindizayo ukuze zenze indawo ethembekile.

I-6) I-rough datum ingasetshenziswa kuphela kanye, ukuze igweme amaphutha amaningi esikhundla.

2. Umgomo wokuqokwa kwe-DATUM

1) I-datum ekhethiwe yokuma izoba lula ukuyithola, ukuvala nokusebenza, futhi kube nokunemba okwenele.

2) Isimiso sokuhlanganiswa kwe-Benchmark. Lapho i-workpiece ibekwe kusethi yokuqeda i-datum, kulula ukucubungula iningi lendawo esele, indlela yokuthola isethi efanayo izosetshenziswa kwimishini ye-CNC yalezi zibalo zalezi zindawo. Lokhu kunganciphisa ukwakheka kwamathuluzi nokukhiqiza, kugwema amaphutha wokuguqula asusene, futhi athuthukise umkhiqizo.

3) Isimiso sokuzenzakalelayo esijwayelekile. Lapho ukuqedwa kokugcina kobuso kudinga ukuqinisekisa ukunemba okuningana, inkomba yokuqamba izokhethwa njengebhentshi lokuma esikhundleni, elibizwa ngokuthi yi-Standard Concembus Enqubweni yokuqeda indawo lapho ukunemba kwesikhundla kungaqinisekisiwe, umgomo wokuhlangana okujwayelekile kufanele amukelwe.

4) Isimiso sezenzele. Lapho ezinye izinqubo zokuqeda indawo yokuqeda indawo zidinga imali encane neyunifomu, ingaphezulu elinqunyelwe ngokwalo lingasetshenziswa njengendlela yokuthola ireferensi, ebizwa ngokuthi yi-Self - Isimiso Sereferemba. Futhi ukunemba kwesikhundla ngalesi sikhathi kuzoqinisekiswa inqubo yamanje.
