Titanium's futsanehileng mocheso conductivity le phahameng lik'hemik'hale reactivity etsa hore ho le tšekamelo ea ho bokooa holim'a metsi nakongMechine ea CNC. Le ha li-geometry tsa lisebelisoa le li-parameter tsa ho itšeha li ithutoa hantle, ntlafatso ea pholiso e ntse e sa sebelisoe haholo ts'ebetsong ea indasteri. Phuputso ena (e entsoeng ka 2025) e sebetsana le lekhalo lena ka ho lekanya hore na ho fana ka pholiso ho ntlafatsa boleng ba ho qetela ntle le ho senya tlhahiso.
Mokhoa
1. Moqapi oa Teko
●Boitsebiso:Lithupa tsa Ti-6Al-4V (Ø50mm)
●Thepa:5-axis CNC e nang le sesebelisoa se pholisang ka har'a sesebelisoa (sebaka sa khatello: 20-100 bar)
●Metrics e lateloang:
Bokhopo bo holimo (Ra) ka ho kopana le profilometer
Ho roala mapheo a lisebelisoa ho sebelisa setšoantšo sa microscope ea USB
Mocheso oa libaka (FLIR khamera ea mocheso)
2. Repeatability Controls
● Ho pheta-pheta liteko tse tharo ho ea ka sete ea paramethara
● Lisebelisoa tsa lisebelisoa li nkeloa sebaka ka mor'a teko ka 'ngoe
● Thempereichara ea tikoloho e tsitsitse ho 22°C ±1°C
Liphetho & Analysis
1. Khatello e Pholisang vs. Surface Finish
●Khatello (bar):20 50 80
●Avg. Ra (μm) :3.2 2.1 1.4
●Tool Wear (mm):0.28 0.19 0.12
Pholiso e phahameng ea khatello (80 bar) e fokolitse Ra ka 56% khahlanong le baseline (20 bar).
2. Nozzle Positioning Liphello
Li-nozzles tse nang le mahlakore a mabeli (15° ho ea ntlheng ea sesebelisoa) li ntlafalitse litlhophiso tsa radial ka:
● Ho fokotsa ho bokellana ha mocheso ka 27% (boitsebiso ba mocheso)
● Ho eketsa bophelo ba lisebelisoa ka 30% (litekanyo tsa ho roala)
Puisano
1. Mekhoa ea Bohlokoa
●Phallo ea Chip:Setsidifatsi sa kgatello e phahameng se pshatla ditjhepisi tse telele, ho thibela ho poma hape.
●Taolo ea Mocheso:Pholiso ea sebakeng sa heno e fokotsa ho khopama ha lisebelisoa.
2. Mefokolo e Sebetsang
● E hloka litlhophiso tse fetotsoeng tsa CNC (bonyane bo boholo ba pompo ea li-bar 50)
● Ha e na litšenyehelo bakeng sa tlhahiso ea molumo o tlaase
Qetello
Ho matlafatsa khatello e pholileng le ho hokahanya ha molomo oa molomo ho ntlafatsa boleng ba titanium haholo. Baetsi ba lokela ho etelletsa pele:
● Ho ntlafatsa ho ≥80 bar coolant systems
● Ho etsa liteko tsa ho beha nozzle bakeng sa lisebelisoa tse khethehileng
Lipatlisiso tse ling li lokela ho hlahloba pholiso e nyalisitsoeng (mohlala, cryogenic+MQL) bakeng sa li-alloys tse thata-to-machine.
