Chii kwomugove uye sei kuverenga here?

Usati kuwana rapera kacho preform kuita zvizhinji remapazi akasiyana. Chimwe chezvinhu zvinokosha pane kutsunga kwomugove kuti kugadzira. saizi Its - ndiwo musiyano pakati kukura workpiece uye kukura mashoko ari pamufananidzo. Munyaya ino, tinodzidza kuti mugove kwakadaro uye sei kuverenga nayo.

marudzi dzichashivirira

Oversize - marongera nesimbi iyo rinobviswa pemvura workpiece kuwana rakapera chikamu. Izvi zvinokosha kuti nechokwadi rakarurama inodiwa kukura uye inodiwa kunaka workpiece pamusoro. Takaona kuti mugove kwakadaro, asi zvino kuziva chii ayo dzakasiyana. Zvichienderana nzira mukugadzira zvikuru zvinoriumba, asi dzichashivirira angava zvenguva, uye mezhduoperatsionnymi zvakafanana. Kazhinji, ekupedzisira vari dzaona nokuwedzera mezhduoperatsionnyh. Kwomugove inogona dzaona sezvo imwe saizi, uye kurutivi.

Kubva iyo ukoshi zvinoenderana?

Takatodzidza akawana kuti mugove kwakadaro, asi zvino tinodzidza zvinhu kungaenderana ukuru hwaro. Pakutanga, Chokwadi, mashoko hwokugadzira mashoko pamusoro yepamusoro uye rakarurama zvikamu. Uyezve, kukura kwomugove kunobva configuration uye mashoko aro ukuru. Chimwe chinokosha kufurira yasarudzwa ukoshi - a mhando okuwana. Hatifaniri kukanganwa pamusoro kugadzwa mashoko ari mudziyo kukanganisa.

The kukarukureta of ngaabvumire munzira mbiri

Takaona kuti vakadaro mugove uye chii zvinoita sei saizi yayo uye ikozvino kuziva sei kuverenga nayo. Kune nzira mbiri: Statistical (tafura) uye Analytical (mumusha macho). Origin tsunga neHurumende Standards, uye maererano kunoenderana mhando workpiece uye kubudiswa nzira. Chokutanga, kuti ngaaverenge kukura ngaabvumire processing Statistical nzira, zvinokosha kuva workpiece machine nzira. Uyezve, kugadzira tolerances dzinopiwa kwesayenzi kuchinja. Zvino, maererano matafura, pamwe runoenzanirana zvinhu vanotumirwa GOSTs mugove R _z uye h. Uyezve, zvinokosha kuti ngaaverenge ukoshi zvachose spatial zvikanganiso. Muzvigadzirwa mvumo akaverenga tabular nzira, zvinokosha kutanga kuverenga kubva wokupedzisira kuchinja, kureva, nekwekupedzesera acho.

Kuverenga kwomugove Analytical nzira kushandisa mutoo.

For cylindrical hukawanika:

For sandara hukawanika:

apo:

• R _z - microroughness mutengo;
• H - kudzika urema rukoko;
• ρ _i-1 - ukoshi zvachose spatial zvarakasiya;
• ε _Ini - workpiece kuisa kukanganisa;
• Ini - ngaabvumire oparesheni ichi.

Zvenguva Kushivirira machine (zvishoma) vari dzaona rurefu chaizvo zvakarurama - kuti micrometer, uye kudiwa kubereka rounding kumusoro.

Kunyange zvazvo zviri mvumo vamwe mhando rinowanikwa, zvakakodzerawo kufunga kuti kukosha kwayo kunofanira kusapfuudza shoma Chip ukobvu, zvinotora nokuveza kushandisa dzaona muitiro danho. Zvechokwadi, mumamiriro ezvinhu akasiyana-siyana uye munzira dzakasiyana-siyana processing munhu workpiece vyshenapisannogo Masvomhu dzingasiyana zvishoma. Somuenzaniso, kubva payakavakirwa kudzika kuremara rukoko hwaputswa kwayo nomugove (h _i-1) kuti ngaakuyire pashure Kupisa kurapwa, sezvo iri kana pamusoro rukoko anofanira kuchengetedzwa.
