Kushata Kwepamusoro muKugadzira: Kuyera, Kukanganisa zvinhu & Kuderedza
Yekupedzisira update:09/01, nguva yekuverenga: 5 mins
Kupedzwa kweSurface yakaoma
Ngatinzwisisei kushata kwepamusoro neshoko rekupedzisira.Maitiro ekunyorovesa pamusoro pezvakagadzirwa zvikamu uye zvigadzirwa zvinozivikanwa sekupedzisa kwepamusoro, iyo inoongororwa uchishandisa roughness.Iyo inonyanya kufarirwa parameter yemasvomhu quantification yeRoughness ndeye Ra.Inoratidza kutsauka kwearithmetical pamusoro pepamusoro.Mudiki Razvinoreva magadzirirwo akatsetseka.
Surface roughness ndiko kusarongeka kwechimiro chepamusoro chakaumbwa nenhevedzano yecrest uye zvidyiro zvimiro.Aya macrest uye madhiri anogona kunge ari microscopic uye anooneka, zvichienderana nekukasharara.Hunhu hwepamusoro hwezvigadzirwa kana zvigadzirwa zvakapedzwa zvakakosha muindasitiri yekugadzira.Izvo hazvisi zvekunaka kwekukwezva asi zvinokanganisa mashandiro ezvikamu uye hunhu hwakazara.
Kuyerwa kweSurface roughness
rough surface profile
Kushata kwepamusoro kunoratidzwa ne"Ra,“uye chikamu chayo mamicrons (µ)Ra inopa avhareji misiyano pakati pecrest (urefu) uye dariro (kudzika) pamusoro pehurefu hwekuyera.
Kuyera kwepamusoro kwakakosha pakugadzira zvikamu zvakavimbika uye zvinowirirana uye zvigadzirwa mukugadzira kwakaringana.Naizvozvo, maparameter epamusoro anofanirwa kuyerwa uye kutariswa kune inodiwa yakatarwa.Semuyenzaniso, kuyera kushata kwepamusoro ndiyo nzira yekuwana inodiwa kupedzwa kwepamusoro.
1. Kuyera neprobe.
Iyi ndiyo nzira yekubata nayo yekuyera kushata kwepasi.Kutora Chiyero, probe kana stylus inofanira kubata pamusoro.
Kuyera Kukasharara neprobe
Iyo skid inofamba yekutanga kumisikidza referensi, uye probe inotevera kumashure kuti ifambe pamusoro pepamusoro kuburikidza nemacrest uye madhiri ichitumira masaini emagetsi kukudziridza chimiro chepamusoro.Mushure meizvozvo, kushata kwepamusoro kunogona kuwanikwa kubva kune yakasikwa mbiri.
2. Optical profilometry
Iyi nzira uses chiedza masaisai kana masaisai eruzha.Chigadzirwa chacho chinotumira mafungu e ultrasonic kumusoro uye inogamuchira zviratidzo.Nzvimbo yeinoratidzwa wave inoshandiswa kugadzira iyo 3D yepamusoro chimiro uye kuverenga iyo Kukasharara.

3. Kuenzanisa
Nenzira iyi, mugadziriinoenzanisa pamusoro pechigadzirwa nechigadzirwa nezvikamu zvakamboyerwauye inosarudza iri padyo vachishandisa pfungwa dzavo.Kunyange zvazvo Iyo isiri nzira yakanyatsojeka, inogona kushandiswa apo yakakwirira yakarurama isingadiwi, uye mamwe mapendi achaiswa pamusoro.
Hukasha vs.Kugadzira
Imwe yeakakosha maratidziro ekuita kwezvikamu zvakagadzirwa ndeye Roughness.Iwo akakosha mazinga ekushata kwepamusoro anotungamira kune makatsemuka paunenge uchishandiswa uye kukudziridza mukana wekuora kwakanyanya kana waratidzwa kune zvakatipoteredza.Uye zvakare, Hushasha hunogona kuderedza kushanda zvakanaka uye pakupedzisira kukuvadza dhizaini uko kuderera kunodiwa nekuti nzvimbo isina kurongeka inowedzera kupokana pakati pezvikamu.
Zvichienderana nekushandiswa, chimwe nechimwe chemuchina chikamu chine muganho wepamusoro wakasiyana wekuoma kwepasi.Semuyenzaniso, zvinhu uko kukweshera kuri kunetseka zvine kushivirira kwakaderera kweKukasharara nekuti maoparesheni anonetsa, uye chikamu chinotsemuka kana Hukasha hwanyanya.
Mashinda uye mating anotarisana anogona kuve nechiyero chakaringana cheHukasha nekuti izvi hazvikanganise kukwirana uye zvinogonesa kukwana pakati pezvikamu.Zvakare, iyo nzvimbo iyo pendi inodiwa inotarisisa imwe dhigirii yeRightness, iyo inovandudza kunamatira uye inoita kuti maitiro ave nyore.

Zvinoreva zvirevo zvinoshandiswa muzviratidzo
Nekuongorora zviratidzo zvehushasha hwepamusoro mudhirowa yekugadzira, vagadziri nevashandisi vanogona kutaura mamiriro ekupedza kwepamusoro mune chero chinhu chakagadzirwa.
Semuenzaniso, CNC opareta anogona kuona kubva kudhizaini yevagadziri kuti ingani zvinhu zvinofanirwa kubviswa kubva pamusoro panguva yekupedzisa.
Ndezvipi zvinhu zvinokanganisa mwero wekushata kwepamusoro?
Zvinhu zvitatu zvinotevera zvinokanganisa kushata kwepamusoro;Kucheka kushanda, Kukuya, uye kudzora paramita (Kucheka kumhanya & chiyero chekudya).
1. Kucheka Operation
Mushure mokunge basa rekucheka rakapedzwa ne CNC machining, chigadziro chekucheka chinosiya zvakasara panzvimbo yekucheka nekuda kwekumanikidzwa panguva yekusunungurwa kwechigadzirwa kubva pakushanda.
Izvi zvakasara (zvinodaidzwa kuti burr) zvinokanganisawo zvikamu 'zvinodiwa dimensional kugadzikana.Zvinhu zvinotevera zvinotarisa ukuru uye huwandu hwezvisaririra pamusoro pechiso chakasiiwa nemudziyo wekucheka.
- Kutsauka mukona yekucheka
- Tooltip radius deflection
- Chiyero chekudyisa
- deformation paunenge uchicheka
2. Kukuya
Iyo nzira yekukuya mukugadzira inoshandisa yakaoma, inoshungurudza midhiya, uye tembiricha inogona kusvika kusvika 1500 ° C panguva yekuita.Mupendero wezvimedu zveabrasive zvinogadzira kupisa kwepurasitiki kuyerera nekuda kwekushisa kwekushanda kwakanyanya, zvichisiya zvishoma roughness pamusoro.
3. Kucheka Speed & Feed Rate
Iyo yakakwira yekucheka kumhanya inowedzera machipisi 'kuumbwa, uye saizi yemachipi ichave yakawedzera.Nokudaro chigadziro chichasiya mamwe mabhura pamusoro pepamusoro nokuti iyo yakakwirira yekucheka ichawedzera kupesana pakati pechombo uye chekucheka pamusoro, kuwedzera kukosha kweRa.Zvakare, chiyero chekudya chepamusoro chichawedzera kureba kwezvisaririra pamusoro.
Ndingaderedza sei kushata kwepamusoro?
· Isa chiyero chakakodzera chekudya nekuti chiyero chekudya chepamusoro chinoita kuti mamwe masara aumbe pane yekucheka.Kuti uderedze Hukasha, shandisa yakanyatsocheka mvura yekucheka uye chaiyo yekucheka maturusi.
· Yakakwira deflection angles inoburitsa machining burrs uye mamaki pamusoro, saka adzikise.
· Nekuti kupfeka kwemidziyo kunowedzera kushata kwepamusoro, Polishi kukuya usati wakuya.
· Iko kukweshera kunowedzerwa nekuzunguzika mumidziyo yekugadzira, izvo zvinoita kuti kumusoro kuve kushata.Nokudaro, usati waenderera mberi nekushanda kwekugadzira, kuderedza vibration uye kuwedzera mvura yekucheka.
· Sarudza iyo machining chishandiso zvinhu zvinoenderana nehunhu hweiyo mbishi zvinhu.Semuenzaniso, kana uri kugadzira zvinhu zvakaoma, shandisa maturusi e-carbide ane mitungamiri.Chishandiso chinofanirawo kuva chakafanana.
Mhedziso
Iyo yepamusoro inofanirwa kugara ichiwira mukati meimwe roughness miganho panguva yekugadzira maitiro zvichienderana nekutsanangurwa kweiyo mechanical chikamu.Ra inoratidza kuti tinofanira kubvuma kana kuramba purojekiti ine chekuita nekupedzwa kwepamusoro.A profilometer inoverengera arithmetic surface roughness nekuona avhareji yehurefu hwezvakakanganiswa zvinoumba chikamu chekukasharara kubva mumutsara wereferensi.
Pakurapa kushata kwepamusoro, kumwe kugadziridzwa kunodiwa, sekubvisa, kukuya, uye kupukuta.Aya maitiro anobatsira kuwana kukosha kwekukasharara mukati memuganho unodiwa.Nekudaro, iyi post-processing inowedzera kumutengo wekugadzira, saka zviri nani kufunga nezve roughness factor mukugadzira chigadzirwa uye kugadzira maitiro.ProleanHubine vagadziri uye mainjiniya vane hunyanzvi mukudzora maitiro uye kupedzisa kwepamusoro.Inzwa wakasunungukataura nesukana iwe uchida chero chirongwa chinowira mukati meinodiwa roughness muganho.
FAQ's
Chii chinonzi kushata kwepamusoro?
Surface roughness ndiyo parameter inopa pfungwa yekupedzisa kwepamusoro muzvikamu zvakagadzirwa uye zvinhu.Inotaurira zvisizvo zvepamusoro uye inofanira kunge iri mukati memuganhu waunoda.
Nzvimbo yakakasharara inokanganisa kunaka kwechigadzirwa here?
Hongu, nzvimbo dzakashata dzine mukana wepamusoro wekuora nekutsemuka.Zvakare, zvinokanganisa kurodzwa kwezvikamu.
Ko Roughness ine chero application yakanaka here?
Hongu, kushata kwepamusoro kunogona kubatsira kana pendi ichida kuiswa nekuti inowedzera kunamira.Zvakare, zvikamu zvinofanirwa kusungirirwa hazvinei neRoughness.
Chii chinorehwa naRa?
Ra inozivikanwa seavhareji yepasi roughness, iyo arithmetic nzira yezvikwiriso zvese zvepamusoro kubva kumutsara wereferensi.
Ndedzipi nzira dzakajairika dzekuyera kushata kwepasi?
Kuenzanisa nechati yakajairwa roughness, Kuyera neprobe, uye Optical profilometry ndidzo nzira nhatu dzakajairwa dzekuyera kushata kwepasi.
