Isu tese takasangana nedambudziko reworkpiece pamusoro chatter panguva yeCNC kutendeuka.Kukurukurirana kwakareruka kunoda kushandazve, uye kutaura kunorema kunoreva kukwenya.Hazvinei kuti inobatwa sei, kurasikirwa.Nzira yekubvisa sei chatter panzvimbo yekushanda yeCNC kutendeuka?
Maitiro ekubvisa Chatter & Vibration Yekushanda Surface muCNC Turning
Kuti tibvise chatter yenzvimbo yekushanda muCNC kutendeuka, isu tinofanirwa kuziva chikonzero chekutaura.
1. Matambudziko emuchina
Pane zviviri zvinokonzeresa zvemuchina chishandiso.
(1) Kana workpiece yakavharwa nevhavha yepamusoro, kuwedzera kwejacking kwakareba, zvichiita kuti kusakwana kuoma.
(2) Muchina wacho pachawo wakashandiswa kwenguva yakareba, kuchengetedza hakuna nguva, uye mabheji emukati uye zvimwe zvikamu zvakasakara.
2. Zvishandiso
Pane zvikonzero zvina zvinogoneka zvemuchina chishandiso.
(1) Chishandiso chekuzorora chinorebesa panguva yekutendeuka, zvichikonzera kusakwana kusimba.
(2) Chipenga chakasakara uye hachina kupinza.
(3) Kusarudzwa kwemichina yekushandisa paramita panguva yekutendeuka haina musoro.
(4) The tip arc yeblade yakakura kwazvo.
3. Matambudziko eWorkpieces
Pane zvinhu zvitatu zvinokonzeresa zvekugadzira.
(1) Zvinhu zvekushandura workpiece zvakanyanya kuoma, izvo zvinokanganisa kutendeuka.
(2) Iyo yekushandura workpiece yakarebesa, uye workpiece haina kuomarara zvakakwana panguva yekutendeuka.
(3) Zvishandiso zvemadziro zvitete hazvina kuomarara zvakakwana kana uchitenderedza matenderedzwa.
Kana kudengenyeka kunoitika panguva yekutendeuka, sei kubvisa dambudziko?
1. Workpiece
Kutanga, tarisa kana pane dambudziko neworkpiece.
(1) Kana workpiece zvinhu kuti akatendeuka yakanyanyisa kuoma, unogona kuchinja muitiro kuderedza kuomarara workpiece, uye ipapo kunatsiridza mune dzimwe nzira gare gare.
(2) Kana workpiece inofanira kutendeuka yakareba, tevera chibatiso chekushandisa kuti uvandudze kugadzikana kwe workpiece.
(3) Kana iyo workpiece yakatetepa-yakavezwa, chishandiso chinogona kugadzirwa kuvandudza kuomarara kana uchitenderedza excircle.
2. Tooling
Tevere, ngationei kana iri dambudziko rekushandisa.
(1) Kana zororo rekushandisa richiwedzera kwenguva yakareba, tarisa kana nzvimbo yekuzorora yepasi inogona kugadziriswa.Kana zvisina kudaro, shandura zororo rekushandisa nesimbi yakakwirira.Kana zvichidikanwa, shandisa anti vibration chishandiso kuzorora.
(2) Kana blade yakasakara, shandura chipande.
(3) Kana chikonzero chiri chekuti iyo yakasarudzwa yemuchina paramita haina musoro, shandura chirongwa uye sarudza inonzwisisika paramita.
(4) The tool tip arc yakakura kwazvo, uye blade inoda kutsiviwa.
3. Muchina wekushandisa
Chekupedzisira, tongai kana paine dambudziko nechishandiso chemuchina uye kana iyo isina kufanira matipi inoshandiswa
(1) Kana iyo isina kunaka yepamusoro ikashandiswa, iyo yepamusoro ine maitiro akanaka inoda kutsiviwa.
(2) Kana chishandiso chemuchina pachacho chikashandiswa kwenguva yakareba uye kugadzirisa kusiri panguva, zvinodikanwa kubata vashandi vekugadzirisa muchina kugadzirisa muchina.
Zvakadini Kana Pasina dambudziko Rinowanikwa?
Kana tikasawana chero matambudziko anoenderana nezviri pamusoro, ndezvipi zvimwe zvatingaite?Inogona kuve yakavakirwa pakutsvagisa pane vibration musimboti wekuseta chishandiso.Parizvino, kune dzimwe nzira dzakananga uye dzinoshanda dzinoshandiswa kunzvimbo yekugadzirisa:
(1) Deredza huremu hwekushanda hwezvikamu zvinokonzera kuzununguka, uye diki iyo inertia, zviri nani.
(2) Ye eccentric workpiece, gadzira inoenderana tooling.
(3) Gadzirisa kana kusungirira zvikamu zvine kuzunguzika kukuru, senge pakati furemu, keji yekushanda, nezvimwe.
(4) Wedzera kuomarara kweiyo system yekugadzirisa, semuenzaniso, shandisa chibatiso chine yakakwira elastic coefficient kana shandisa yakakosha anti vibration simba rakasanganiswa neane simba damper kutora simba rekuita.
(5) Kubva pakuona kweblade uye workpiece kutenderera nzira.
(6) Shandura chimiro cheturusi uye kona yekudyisa, iyo diki yetipi redhiyo iri, zvirinani, uye kuderedza kucheka kuramba.Iyo lateral inclination angle inofanirwa kuve yakanaka kuita kuti nzira yekucheka iswedere kune yakatwasuka.Iyo caster angle iri nani kuve yakanaka, asi kunyangwe iyo chip yekubvisa kugona iri kushomeka, inogona kazhinji kushandiswa kuita iyo caster angle isina kunaka, asi ichiramba ichichengetedza kukosha kweiyo yekucheka maitiro.
