CNC Machining Technology Processing
1. Ndedzipi nzira nhatu dzeworkpiece clamping?
A. Kurovera mugadziriro;
B. Tsvaga zvakananga chirambi;
C. Mutsetse uye tsvaga chirambi chepamutemo.
2. Chii chinosanganisira maitiro ehurongwa?
Chishandiso chemuchina, workpiece, fixture, yekucheka chishandiso
3. Kuumbwa kwemaitiro ekugadzira?
Kukasharara, semi-kupedzisa, kupedza, superfinishing
4. Mabhenji anoiswa muboka sei?
1. Dhizaini mabhenji
2. Process datum: process, measurement, assembly, positioning: (yekutanga, yekuwedzera): (rough datum, fine datum)
5. Kururama kwemichina kunosanganisirei?
1. Kururama kwedimensional
2. Kururama kwechimiro
6. Ndezvipi zvikanganiso zvepakutanga mukugadzirisa?
1) Kukanganisa kwenheyo
2) Positioning kukanganisa uyeKugadzirisa kukanganisa
3) Kukanganisa kunokonzerwa neworkpiece yakasara kushushikana
4) Tool fixture kukanganisa uye Tool kupfeka
5) Machine tool spindle kutenderera kukanganisa
6) Machine tool guide guide kukanganisa
7) Chikanganiso chekutumira muchina
8) Process system stress deformation
9) Process system kupisa deformation
10) Chiyero chikanganiso
7. Mhedzisiro yekuomarara kwehurongwa hwemachining iko (muchina deformation, workpiece deformation)?
1) Chikanganiso chechimiro chekushanda chinokonzerwa nekushandurwa kwechinzvimbo chesimba rekucheka.
2) Machining zvikanganiso zvinokonzerwa ne clamping simba uye giravhiti
3) Kupesvedzera kwesimba rekutapurirana uye inertia simba pane machining kururama.
8. Ndedzipi zvikanganiso zvinotungamira zvemuchina chishandiso chegwaro uye zvikanganiso zvekutenderera kwe spindle?
1) Iyo njanji inotungamira inonyanya kusanganisira iyo hama yekuchinjisa kukanganisa pakati pechishandiso uye workpiece munzira yekukanganisa-inonzwiwa inokonzerwa negwara renjanji.
2) Radial runout ye spindle · axial runout · Inclination swing.
9. Chii chinonzi "error kudzokorora"?Chii chinonzi chikanganiso chekuratidza coefficient?Chii chingaitwa kuderedza kukanganisa?
Nekuda kwekuchinja kwe process system kukanganisa uye deformation, iyo isina chinhu chikanganiso chinoratidzwa kune workpiece.
Matanho: wedzera huwandu hwekucheka, wedzera iyo process system kuoma, kuderedza chikafu, kunatsiridza iyo isina kujeka chokwadi.
10. Machine tool transmission chain transmission error analysis?Matanho ekuderedza kutapurirana cheni kutapurirana kukanganisa?
Mhosho yekuongorora: inoyerwa neAngle kukanganisa kwechikamu chekupedzisira chedhiraivha.
Matanho:
1) Iko kushomeka kwenhamba yekutapurirana cheni, iyo ipfupi chetani yekutapurirana, idiki δ φ, iyo yakakwirira yekururama.
2) Iyo diki iyo yekufambisa reshiyo I, kunyanya chiyero chekutapurirana pamigumo yese
3) Sezvo kukanganisa kwezvikamu zvekupedzisira zvezvikamu zvekutapurirana zvine simba guru, zvinofanirwa kuitwa zvakanyatsonaka sezvinobvira.
4) Adopt calibration mudziyo
