Kukasharara kwepamusoro (surface roughness) zvinoreva kusaenzana kwenzvimbo yakagadzikwa ine kapakati diki nenhongonya nemipata. Chinhambwe (wave distance) pakati pemafungu maviri esaisai kana maviri mafungu madhiri idiki kwazvo (isingasviki 1mm), inova microscopic geometric kukanganisa. Iyo idiki iyo kushata kwepamusoro, ndiko kutsetseka kwepamusoro. Kazhinji, maitiro e morphological ane chinhambwe chesaisai isingasviki 1 mm anokonzerwa nekukasharara kwepasi, maitiro e morphological ane saizi ye 1 kusvika 10 mm anotsanangurwa sekupenya kwepasi, uye morphological maitiro ane saizi yakakura kupfuura 10 mm inotsanangurwa sepamusoro penzvimbo.
Kushata kwepamusoro kunowanzo kukonzerwa nemaitiro ekugadzirisa anoshandiswa uye zvimwe zvinhu, senge kupokana pakati pechishandiso uye chikamu chepamusoro panguva yekugadziriswa, iyo yepurasitiki deformation yesimbi yepamusoro kana machipisi akaparadzaniswa, yakakwirira-frequency vibration mu process system. , etc. Pamusana pemaitiro akasiyana-siyana ekugadzirisa uye workpiece zvinhu, kudzika, kuwanda, chimiro uye kugadzirwa kwemavara akasiiwa panzvimbo yakagadziriswa zvakasiyana.
Hushasha hwepamusoro hune hukama nekuita kwekuenzanisa, kupfeka kuramba, simba rekuneta, kuomarara kwekubata, kuzununguka uye ruzha rwemakina zvikamu, uye zvine chekuita kwakakosha pahupenyu hwesevhisi uye kuvimbika kwezvigadzirwa zvemichina.
Evaluation parameters
urefu hunhu parameters
Contour arithmetic zvinoreva kutsauka Ra: zvinoreva arithmetic yeukoshi hwakakwana hwecontour offset mukati mesampling urefu lr. Mukuyera chaiko, kana mapoinzi ekuyerwa akawedzera, ndipo paanonyanya kurongeka Ra ari.
Maximum profile urefu Rz: chinhambwe chiri pakati pemutsetse wepamusoro uye wepasi pemupata.
Assessment hwaro
Sampling urefu
Sampling urefu lr hurefu hwemutsara wereferensi wakatsanangurwa pakuongorora kushata kwepasi. Kureba kwesampling kunofanirwa kusarudzwa zvichienderana nechimiro chepamusoro uye chimiro chechimiro chechikamu, uye kureba kunofanirwa kusarudzwa kuratidza maitiro ehukukutu hwepamusoro. Kureba kwesampling kunofanirwa kuyerwa munzira yakajairika yeiyo chaiyo yepamusoro chimiro. Kureba kwesampling kunotsanangurwa uye kusarudzwa kudzikamisa uye kuderedza mhedzisiro yekubhururuka kwepasi uye kuumba zvikanganiso pazviyero zvehukukutu hwepasi.
Mumunda wekugadzira michina, madhirowa anosanganisira simbi yekutsikirira zvikamu, sheet simbi zvikamu, machini zvikamu, nezvimwe zvinoratidzwa zvakanyanya nekugadzirwa kwepamusoro roughness zvinodiwa. Naizvozvo, mumaindasitiri akasiyana-siyana akadai sezvikamu zvemotokari, michina yeinjiniya, midziyo yekurapa, aerospace, uye michina yekuvaka ngarava, nezvimwe zvese zvinogona kuonekwa.
