Ukuhlaziywa kwe-CMM: Kusukela Ezimisweni Eziyisisekelo Kuya Ekuphumeleleni Ekulinganiseni Izimbobo Ezigobile

I-coordinate ezintathu Umshini Wokulinganisa, ngokusebenzisa ukumodela kwezibalo kanye nokucubungula i-algorithm yamaphuzu amaningi, kwakhiwa kabusha imodeli yedijithali enezinhlangothi ezintathu yomsebenzi, ngaleyo ndlela kufezwe ukulinganisa okunembile kusukela ezintweni ezilula zejiyometri (amaphuzu, imigqa, izindawo) kuya ezindaweni eziyinkimbinkimbi kanye nezindawo ezikhululekile. Kusebenza ezimbonini ezahlukahlukene, njenge:

1. Enqubweni yokukhiqiza izimoto, umshini wokulinganisa onezinhlanganisela ezintathu okuhilelekile ekutholeni amapharamitha abalulekile njengokuqina kwembobo ye-crankshaft ebhulokini lesilinda senjini kanye nokunemba kwendawo kwezimbobo zomhlahlandlela we-valve ekhanda lesilinda.
2. Emkhakheni wezindiza lapho ukunemba kokulinganisa kudinga kakhulu, umshini wokulinganisa ohlanganisa izinhlangothi ezintathu usebenzisa ama-probe okuskena anembe kakhulu kanye nokuskena okuhlakaniphile okuhlelekile kwamaphuzu angamashumi ezinkulungwane ukwakha imodeli ye-blade enezinhlangothi ezintathu, bese usebenzisa ukuhlaziywa okuzinikele. Isofthiwe I-PowerBlade yokuhlola ngokuphelele izinkomba ezibalulekile zamapharamitha njengemiphetho ehamba phambili nelandelanayo, iphrofayili ye-blade, ubude be-chord, i-angle ye-chord, ukunemba kwesikhundla, ukujiya okuphezulu, ukujiya komphetho, ubulukhuni, kanye ne-angle yokujika, ukufeza ukuskena okuqhubekayo, okusheshayo, kanye nokungayeki kwama-curve ayinkimbinkimbi, ukubamba ngokugcwele izici zosayizi ogcwele zephrofayili ye-blade backside/back basin, imiphetho ehamba phambili nelandelanayo, i-dovetail kanye ne-slot, njll., ukuqinisekisa ukuthi ukunemba kwe-contour ye-blade ngayinye kulawulwa ngaphakathi kwe-±0.005mm.
3. Embonini ye-semiconductor, kungakhathaliseki ukuthi yimikhono elula yomgodi noma izingxenye eziyinkimbinkimbi ezingajwayelekile, ukulinganisa okuhlanganisiwe okuthathu kuhlanganisa ngomshini izidingo zokutholwa kwezingxenye ezahlukahlukene eziyinhloko zemishini ye-semiconductor.

Ubunzima kubuchwepheshe bokulinganisa obunezinhlangothi ezintathu: ukulinganisa imigodi ethambekile Izakhiwo ezifana nemigodi kawoyela ethambekile kanye nemigodi yepayipi eliqondisa ama-valve ezinjinini zezimoto zivame ukwakha i-engeli engu-30° kuya ku-60° ngobuso obubhekiselwe. Izindlela zendabuko azikwazi ukuzilinganisa ngokunembile. Ubunzima kubuchwepheshe bokulinganisa imigodi ethambekile buseku:

1. Umkhawulo endleleni yevektha evamile: Ngesikhathi sokulinganisa, i-probe kumele ithintwe ngendlela ye-axis yembobo ethambekele (indlela yevektha evamile); ngaphandle kwalokho, kuzokwenzeka amaphutha okubuka;
2. Ukuguqulwa kwesistimu yokuxhumanisa: Uma umsebenzi ubekwa ngokungahleliwe, kuba nokuphambuka kwe-engeli yendawo phakathi kwesistimu yokuxhumanisa imbobo ethambekele kanye nesistimu yokuxhumanisa ithuluzi lomshini;
3. Ukuvinjelwa kokunyakaza kweprobe: Amaprobe aqinile awakwazi ukuzungeza ngokukhululekile futhi kunzima ukuwavumelanisa nendawo ethambekele kuyo.

Izixazululo Zemboni

1. Ubuchwepheshe Bokujikeleza Kwe-Probe

Amathuluzi okulinganisa aphezulu afakwe isisekelo se-probe esijikelezayo esingu-360°. Ngokulungisa okuzenzakalelayo kwesiqondiso se-angle ye-A/B, i-probe ihlala ithinta i-workpiece ngendlela evamile yembobo ethambekele;

2. Ukuqondaniswa Kwesistimu Yokuxhumanisa Okuhlakaniphile

Kumakhanda okulinganisa angenakujikeleziswa, kusetshenziswa isimiso sokuqondanisa esingu-3-2-1. Ukuphindaphinda nokufakwa kahle kudala uhlelo lokuhlanganisa:

(1) Indiza yokubhekisela ekulinganisweni (amaphuzu ama-3 asungula i-Z-axis)

(2) Umugqa wokubhekisela wokulinganisa (amaphuzu ama-2 asungula i-X-axis)

(3) Umsuka wereferensi yokulinganisa (iphuzu eli-1 lisungula uhlelo lokuxhumanisa)

(4) Ngokubala ukujikeleza okunezinhlangothi ezimbili, uhlelo lokuxhumanisa lwamathuluzi omshini luguqulwa lube uhlelo lokuxhumanisa lwezingxenye zomsebenzi.
