I-Five-eksisi CNC Machining Of Special-Shaped Bodies

Ngokuthuthuka okusheshayo kwe-Aerospace, izikhali, imikhumbi, izimoto nezinye izimboni zokukhiqiza imishini, ukwakheka kwezingxenye zomkhiqizo sekuyinkimbinkimbi ngokwengeziwe futhi kuyinkimbinkimbi. Izikhungo ezijwayelekile ze-3-axis CNC machining azisakwazi ukuhlangabezana nezidingo zemishini. Ukuvela kwezikhungo zemishini eyi-5-axis CNC kuye kwavumelana nezidingo zomkhiqizo futhi sekuyimpumelelo.
Ukuqondiswa kwentuthuko nokwandiswa kobuchwepheshe bokwenza imishini. Ukuhlose engxenyeni emise okhethekile ngendwangu engaphansi (bheka uMdwebo 1), isikhungo sokuxhuma se-axis ezinhlanu nge-turntables ezimbili singaqedela ukwenziwa kwazo zonke izinqubo ekucingeni okukodwa, okuxazulula inkinga yezingxenye ezigobile ezingakwazi ukuqedwa ngamathuluzi womshini we-CNC-axis amathathu. Machining.

1 Ukuhlaziywa kwemishini yezingxenye

Kungabonakala kusuka kuMdwebo 1 ukuthi isitho somzimba esimise okhethekile sakhiwe ngokuyinhloko ngomzimba wenkomishi omise okwe-U, isisekelo nobuso boshintsho, kanye machining impahla yinsimbi engu-45. Isakhiwo sibonakala silula, kepha ngenxa yendawo engaphansi, izingxenye azikwazi ukucutshungulwa ngethuluzi lomshini we-CNC-axis amathathu. I-axis emihlanu yokuxhuma i-CNC machining isikhungo ingeza izimbazo ezimbili ezijikelezayo ngesisekelo sezinsimbi ezintathu eziqondile X, Y, no-Z, ezingalawula ukuqondiswa kwe-eksisi yethuluzi ukushintsha ngokuhambisana nesiqondiso esivamile sendawo esetshenzisiwe, ukuze ingacubungula inkimbinkimbi Ubuso obugobile noma indawo egobile engakwazi ukucubungulwa ngokuphelele ngama-eksisi amathathu. Ngakho-ke, izingxenye ezikhethekile ezimise zidinga ukucutshungulwa isikhungo semishini ye-axis emihlanu.

2 Parametric ukumodeliswa kwezingxenye

Umdwebo 2 Imodeli ye-3D yezitho zomzimba ezikhethekile ezimise ukwakheka kwe-geometric yezingxenye ezisebenzisa i-CAXA Manufacturing Engineer 2011 software [2]

• (1) Sebenzisa umyalo wokubamba iqhaza ekukhiqizeni inkomishi eguquliwe emise okwe-U;
  
• (2) Isisekelo sakhiwa ngokwelula nokungeza izinto;
  
• (3) Sebenzisa umyalo wenguquko ukukhiqiza imodeli ephelele yomzimba wobufokazi (bona Umfanekiso 2).

3 Isu lemishini yokuhlela imishini enzima yezingxenye.

Ukuze kuthuthukiswe ukusebenza kahle kwemishini, umsebenzi we-eksisi ongaguquki nokusika okungamakhemikhali kufanele kusetshenziswe kuqala, futhi isigayo sokugcina esisezingeni eliphansi sisetshenziselwa ukukhahlela okungenalutho ukuqinisekisa ukuthi isabelo semishini enkulu siyasuswa ngesikhathi esifushane.

Kuphelile. Sebenzisa umsebenzi wokuxhumeka kwe-axis emihlanu bese usebenzisa ithuluzi lokujwayela ithuluzi eliguqulelwe kuzici zejometri zobuso obenziwe ngomshini ukwenza imishini yokuqeda ngomphela ezindaweni ezahlukahlukene ukuqinisekisa ukuthi umkhawulo omkhulu ngemuva kokukhishwa okunzima ususiwe, ukuze indawo ngayinye eyenziwe ngomshini igcine indawo efanelekile kanye nomugqa wokuqeda umfaniswano. ukuqeda. Ukuze kuqinisekiswe ukunemba, ikhwalithi ebusweni nokusebenza kahle kwezingxenye zemishini, umsebenzi wokuxhuma ama-axis amahlanu ekugcineni usetshenziselwa ukuqeda izindawo ezahlukahlukene nge-cutter milling cutter.

4 Ithuluzi lokukhiqiza indlela

Ukukhiqizwa kwamathuluzi we-trajectories kuyisixhumanisi esiyinhloko ekuqapheliseni imishini ye-CNC yezindawo ezigobile. I-trajectory yethuluzi elifanele ayikwazi ukuthuthukisa kuphela ikhwalithi nokusebenza kahle kwemishini ebusweni, kepha futhi inikeze ukudlala okugcwele kumakhono wokuchofoza amathuluzi womshini we-CNC [3-6]

Enkambeni yokuqedela, i-U emise inkomishi yomzimba ephendukezelwe futhi indawo engenhla yesisekelo icutshungulwa ngokusebenzisa i-ball8 ball end milling cutter kanye ne-axis side milling esetshenziswayo, futhi inkomishi yomzimba yenkomishi e-U emise u-U indawo icutshungulwa nge-8 ball end milling cutter. Ukuncintisana kwe- umphini wanezela kahle

Kulesi machining yomzimba okhethekile, i-roughing isebenzisa indawo yendiza eyi-3-eksisi, futhi okungenalutho kucutshungulwa ngezendlalelo ezine-8 yesiphetho esigaywe phansi. Indawo ebusayo yendiza ingasusa kahle amamajini amakhulu futhi idale izimo zemishini yokuphela kokuqeda. . Indlela yethuluzi ikhonjisiwe kuMdwebo 3. Enkambeni yokuqedela, umzimba wenkomishi omise okwe-U ongaphezulu nendawo engaphezulu yesisekelo isebenzisa i-8 cut-milling cutter cutter, esebenzisa i-3-axis ukukhiqiza i-trajectory futhi iphendukela kuma-eksisi amahlanu wokugaya ohlangothini lwama-eksisi amahlanu. Ukugaya ohlangothini lwama-eksisi amahlanu kungathola imiphumela engcono. Ubuso bungathuthukisa ukusebenza kahle kokusika futhi kugweme ukusika ngejubane kwethuluzi ngesikhathi se- inqubo machining. I-engeli phakathi kwe-eksisi yethuluzi nobuso bemishini ingalawulwa ngokubeka imingcele yemishini. Amasethingi wepharamitha yokulawula i-axis akhonjiswa kuMdwebo 4. Ukuqedwa kokuphothuliwe kwendebe yangaphakathi yenkomishi emise okwe-U kusetshenziswa isikhulisi sokugaya se-ball8 esine-3-axis parametric line. Ubuso boshintsho bucutshungulwa ngokugaya ohlangothini olunama-eksisi amahlanu. Ukwengeza okuhle kwezingxenye
Indlela yethuluzi ikhonjisiwe kuMdwebo 6.

5 Simulation machining izingxenye

Ngemuva kokuthi ifayili lesikhundla sethuluzi lenziwe, liguqulwa libe uhlelo olujwayelekile lwe-NC ngokusebenzisa ukusethwa kwemishini eminingi, bese uhlelo olwenziwe lwe-NC lungeniswa kusoftware ye-VERICUT7.0 NC yokulingisa imishini yokulingisa yengxenye. Ithuluzi lomshini elakhiwe ngesikhathi semishini yokulingisa kufanele lihambisane nesakhiwo sethuluzi lomshini langempela, futhi isikhundla sokufakwa kwezingxenye kufanele futhi sihambisane nesimo sangempela sethuluzi lomshini. Ngokusebenzisa ukumbumbuluzwa kwemishini, ukuqondisisa kwendlela yethuluzi kungaqinisekiswa, ukuphazanyiswa kanye nokushayisana komkhuba enqubeni yangempela yokwenza imishini kungahlolwa, futhi ukunemba kwezilungiselelo zangemva kokumatanisa nohlelo olwenziwe lwe-CNC machining kungaqinisekiswa, ngaleyo ndlela kulungiselelwe Ithuluzi indlela nokunciphisa machining langempela izingxenye. Izinga lephutha lithuthukise ukusebenza kahle kwemishini nokunemba kwezingxenye.

6 machining langempela izingxenye amathuluzi umshini

Ngemuva kokudluliswa kokulingiswa kwengxenye kudlulisiwe, uhlelo lwe-CNC olwenziwe kahle lungangeniswa kuthuluzi lomshini langempela lokukhishwa kwengxenye. I ezimbili-turntable ezinhlanu-eksisi nokuxhumana CNC machining isikhungo esetshenziswa machining langempela izingxenye, i-eksisi C kungaba ngokuqhubekayo ukushintshanisa uhla 0 ° kuya 360 °, futhi-eksisi kungaba jika emuva naphambili uhla -10 ° kuya ku-100 °. Okungenalutho kuboshwe ngqo ngezinzipho ezintathu ezifakwe ku-turntable, futhi zonke izingxenye zicutshungulwa ngocingo olulodwa. Ngemuva kokuhlolwa, ukunemba kobukhulu nekhwalithi yendawo konke kufanelekile. Into esetshenzisiwe ikhonjisiwe kuMdwebo 8.
