CNC Machining Technology Processing
1. Mekhoa e meraro ea clamping ea workpiece ke efe?
A. Clamping ho fixture;
B. Fumana ka ho toba clamp e hlophisitsoeng;
C. Mola 'me u fumane seqhomane sa molao.
2. Tsamaiso ea ts'ebetso e kenyelletsa eng?
Sesebelisoa sa mochini, sesebediswa sa mosebetsi, sebopeho, sesebelisoa sa ho seha
3. Sebopeho sa mokhoa oa mochine?
Ho qhoqhoa, ho qetela, ho qeta, ho qetela
4. Lipalo-palo li aroloa joang?
1. Lipalo tsa moralo
2. Lethathamo la datha: ts'ebetso, tekanyo, kopano, boemo: (ea pele, ea tlatsetso): (matla a macha, datum e ntle)
5. Ho nepahala ha mochine ho akarelletsa eng?
1. Ho nepahala ha dimensional
2. Ho nepahala ha sebopeho
6. Liphoso tsa pele ke life nakong ea ts'ebetso?
1) Phoso ea molao-motheo
2) Positioning phoso lePhoso ea ho lokisa
3) Phoso e bakiloeng ke khatello ea kelello ea workpiece
4) Phoso ea ho lokisa lisebelisoa le ho roala ha Tool
5) Phoso ea ho potoloha ha spindle ea mochini
6) Phoso ea tataiso ea lisebelisoa tsa mochini
7) Phoso ea phetisetso ea sesebelisoa sa mochini
8) Ho senyeha ha khatello ea tsamaiso ea tsamaiso
9) Ho senyeha ha mocheso oa tsamaiso ea tshebetso
10) Phoso ea tekanyo
7. Liphello tsa ho satalla ha sistimi ho nepahala ha mochini (mochine deformation, workpiece deformation)?
1) Phoso ea sebopeho sa workpiece e bakoang ke phetoho ea boemo ba matla a ho itšeha.
2) Liphoso tsa machining tse bakoang ke matla a clamping le matla a khoheli
3) Tšusumetso ea matla a phetisetso le matla a inertia mabapi le ho nepahala ha machining.
8. Liphoso tse tataisang tsa tataiso ea sesebelisoa sa mochini le liphoso tsa ho potoloha ha spindle ke life?
1) Seporo sa tataiso haholo-holo se kenyelletsa phoso ea ho falla e lekanyelitsoeng pakeng tsa sesebelisoa le workpiece ka tataiso e nang le phoso e bakoang ke seporo sa tataiso.
2) Radial runout of spindle · axial runout · Iclination swing.
9. Ke ketsahalo efe ea "error duplication"? Coefficient e bonahatsang phoso ke eng? Ho ka etsoa eng ho fokotsa phoso?
Ka lebaka la phetoho ea phoso ea sistimi le deformation, phoso e se nang letho e bonts'oa karolo ea mosebetsi.
Mehato: eketsa palo ea ho itšeha, eketsa boima ba sistimi, fokotsa phepelo, ntlafatsa ho nepahala ho se nang letho.
10. Tlhahlobo ea phoso ea phetisetso ea sesebelisoa sa mochini? Mehato ea ho fokotsa phoso ea phetiso ea ketane ea phetiso?
Tlhahlobo ea phoso: e lekantsoe ka phoso ea Angle ea karolo ea ho qetela ea ketane ea koloi.
Mehato:
1) Ha palo ea ketane ea phetiso e fokotsehile, ketane ea phetiso e khutsufala, e nyane δ φ, ho nepahala hoa holimo.
2) E nyenyane karo-karolelano ea phetiso I, haholo-holo karo-karolelano ea phetiso lipheletsong ka bobeli
3) Kaha phoso ea likarolo tsa ho qetela tsa likarolo tsa phetisetso e na le tšusumetso e kholo ka ho fetisisa, e lokela ho etsoa e nepahetse ka hohle kamoo ho ka khonehang.
4) Amohela sesebelisoa sa calibration
