Kodi kulolerana kwa geometric ndi chiyani

ISO imatanthawuza kulolerana kwa geometric monga "Mafotokozedwe azinthu zamtundu wa Geometrical (GPS) -Kulolera kwa geometrical-Kulolera mawonekedwe, mawonekedwe, malo ndi kutha".Mwa kuyankhula kwina, "makhalidwe a geometrical" amatanthauza mawonekedwe, kukula, ubale wa malo, ndi zina zotero za chinthu, ndipo "kulolera" ndiko "kulekerera zolakwika".Makhalidwe a "kulekerera kwa geometric" ndikuti sikuti amangotanthauzira kukula kwake, komanso kulolerana kwa mawonekedwe ndi malo.

Kusiyana pakati pa kulekerera kwa dimensional ndi geometric:

Njira zolembera zojambulazo zitha kugawidwa m'magulu awiri: "dimensional tolerances" ndi "geometric tolerances".Dimensional tolerances amalamulira kutalika kwa gawo lililonse.

Kulekerera kwa geometric kuwongolera mawonekedwe, kufanana, kutengera, malo, kuthamanga, ndi zina zotero.

Chojambula cha Dimensional Tolerance

Kujambula kwa geometric tolerance

Zimatanthauza "onetsetsani kuti pamwamba A sichidutsa kufanana kwa 0.02".

Chifukwa chiyani muyenera kuyika kulolerana kwa geometric?

Mwachitsanzo, poyitanitsa gawo la mbale, wopanga adatchula kulolerana kofanana ndi pansipa.

A Gulu la kulolerana

Komabe, malinga ndi zojambula pamwambapa, wopanga angapereke zigawozi.

A Gulu la kulolerana

Zina zitha kukhala zosayenera kapena zolakwika ngati kufanana sikunazindikiridwe pachithunzicho.

Wopangayo alibe udindo, koma m'malo mwake kulolerana kwa wopanga.Kujambula kwa gawo lomwelo lolembedwa ndi kulekerera kwa geometric kumatha kupanga mapangidwe omwe akuwonetsedwa pansipa.Zambiri za kulolerana kwa geometric, monga "parallelism" ndi "planarity", zimawonjezedwa ku chithunzicho potengera chidziwitso cha kukula.Izi zimathandiza kupewa mavuto omwe amadza chifukwa chongolemba zololera.

Mwachidule, kugwiritsa ntchito kulekerera kwa geometric kumatha kufotokoza bwino komanso mwachangu zomwe wopanga akufuna, zomwe sizingatheke ndi kulolerana kwazithunzi.

Tanthauzo mu ISO

Kugwirizana pakati pa kukula ndi mawonekedwe akufotokozedwa motere:

Zithunzi za ISO8015-1985zomwe zikuwonetsedwa m'mapulani, monga kukula ndi malire a mawonekedwe, sizikugwirizana ndi kukula, malire, kapena zizindikiro zina ndipo zimagwira ntchito paokha pokhapokha zitanenedwa.

Monga tanena kale, mfundo yodziyimira pawokha ndi muyezo wapadziko lonse wofotokozedwa ndi ISO.Komabe, makampani ena aku US sangatsatire mfundo yodziyimira pawokha molingana ndi malangizo a ASME (American Society of Mechanical Engineers).Kuti mupewe chisokonezo chilichonse panthawi yamalonda ndi makampani akunja, tikulimbikitsidwa kukambirana ndi kufotokozera zofunikira pasadakhale.
