Manyuko ekukanganisa kwakasimba kweMuchina wekuyera wekubatanidzaZvinonyanya kusanganisira: kukanganisa kweCoordinate Measuring Machine pachayo, sekukanganisa kweguiding mechanism (mutsetse wakatwasuka, kutenderera), kushanduka kwereference coordinate system, kukanganisa kweprobe, kukanganisa kwehuwandu hwakajairika; kukanganisa kunokonzerwa nezvinhu zvakasiyana-siyana zvine chekuita nemamiriro ekuyera, zvakaita sekukanganisa kwenzvimbo yekuyera (tembiricha, guruva, nezvimwewo), kukanganisa kwenzira yekuyera uye kukanganisa kwezvimwe zvinhu zvisina chokwadi, nezvimwewo.
Manyuko ekukanganisa emuchina wekuyera macoordinate akaomarara zvekuti zvakaoma kuona nekuaparadzanisa rimwe nerimwe woagadzirisa, uye kazhinji ndiwo chete manyuko ekukanganisa ane simba guru pakururama kwemuchina wekuyera macoordinate neayo ari nyore kupatsanura ndiwo anogadziriswa. Parizvino, chikanganiso chinonyanya kutsvakurudzwa idambudziko remuchina wekuyera macoordinate. Mazhinji eCMM anoshandiswa mukugadzira maoorthogonal coordinate system CMMs, uye kune general CMMs, chikanganiso chemuchina chinonyanya kureva chikanganiso chechikamu chekufamba, kusanganisira chikanganiso chekuisa, chikanganiso chekufamba kwakatwasuka, chikanganiso chekufamba kweangular, uye chikanganiso chekumira.
Kuongorora kururama kwemuchina wekuyera wekubatanidzakana kuti pakugadzirisa zvikanganiso, muenzaniso wekukanganisa kwakajairika kwemuchina wekuyera macoordinate unoshandiswa sehwaro, umo tsananguro, ongororo, kutumira uye kukanganisa kwese kwechinhu chimwe nechimwe chekukanganisa kunofanirwa kupihwa. Chinonzi kukanganisa kwese, mukusimbiswa kwekururama kweCMMs, chinoreva kukanganisa kwakabatana kunoratidza hunhu hwekururama kweCMMs, kureva, kururama kwechiratidzo, kururama kwekudzokorora, nezvimwewo: mu tekinoroji yekugadzirisa zvikanganiso yeCMMs, zvinoreva kukanganisa kwevector yenzvimbo.
Kuongorora kukanganisa kwemuchina
Hunhu hweCMM, gwara rekutungamira rinoganhurira madhigirii mashanu erusununguko kuchikamu chinotungamirirwa nacho, uye sisitimu yekuyera inodzora dhigirii rechitanhatu rerusununguko munzira yekufamba, saka nzvimbo yechikamu chinotungamirirwa muchadenga inosarudzwa negwara rekutungamira uye sisitimu yekuyera yairi.
Kuongorora kukanganisa kweprobe
Kune mhando mbiri dzeCMM probes: contact probes dzakakamurwa kuita mapoka maviri: switching (inozivikanwawo setouch-trigger kana dynamic signaling) uye scanning (inozivikanwawo seproportional kana static signaling) zvichienderana nechimiro chadzo. Kukanganisa kweSwitching probe kunokonzerwa neswitch stroke, probe anisotropy, switch stroke dispersion, reset dead zone, nezvimwewo. Kukanganisa kweScanning probe kunokonzerwa neforce a displacement relationship, displacement a displacement relationship, cross-coupling interference, nezvimwewo.
Kurova kweprobe yekuchinja kweprobe uye kubata kwebvudzi reprobe, kutsauka kwedaro. Uku ndiko kukanganisa kwesystem yeprobe. Kukanganisa kweprobe kusaenderana kwekurova kwekuchinja kwemativi ese. Iko kukanganisa kwakarongwa, asi kazhinji kunoonekwa sekukanganisa kwakasarudzika. Kuora kwekufamba kweswitch kunoreva mwero wekupararira kwekufamba kweswitch panguva yekuyerwa kwakadzokororwa. Kuyerwa chaiko kunoverengerwa sekuchinja kwakajairika kwekufamba kweswitch munzira imwe chete.
Reset deadband zvinoreva kutsauka kwetsvimbo yeprobe kubva panzvimbo yekuenzana, kubvisa simba rekunze, tsvimbo muchirimo inogadziriswazve, asi nekuda kwebasa rekukweshana, tsvimbo haigone kudzokera kunzvimbo yekutanga, ndiko kutsauka kubva panzvimbo yekutanga ndiyo deadband yekugadzirisa.
Chikanganiso chakabatanidzwa cheCMM
Chikanganiso chinonzi relative integrated error mutsauko uripo pakati pekukosha kwakayerwa ne true value ye point-to-point distance iri munzvimbo yekuyera yeCMM, iyo inogona kuratidzwa nefomula inotevera.
Chikanganiso chakabatanidzwa chehukama = kukosha kwekuyera daro kukosha kwechokwadi kwedaro
Kuti CMM quota igamuchirwe uye kuti CMM igadziriswe nguva nenguva, hazvidikanwi kuziva chaizvo chikanganiso chepoindi yega yega munzvimbo yekuyera, asi kungoziva kururama kwechinhu chinoyera macoordinate, icho chinogona kuongororwa ne relative integrated error yeCMM.
Chikanganiso chakabatanidzwa hachiratidzi zvakananga mhedzisiro yechikanganiso uye chikanganiso chekupedzisira chekuyera, asi chinongoratidza hukuru hwechikanganiso pakuyera zviyero zvine chekuita nedaro, uye nzira yekuyera iri nyore.
Chikanganiso che "space vector" cheCMM
Kukanganisa kwevector yenzvimbo zvinoreva kukanganisa kwevector chero kupi zvako munzvimbo yekuyera yeCMM. Ndiwo musiyano uripo pakati penzvimbo yakatarwa munzvimbo yekuyera muhurongwa hwakakodzera hwekona yekurudyi uye macoordinates ane mativi matatu anoenderana muhurongwa chaihwo hwecoordinates hwakatangwa neCMM.
Mupfungwa, chikanganiso che "space vector error" i "comprehensive vector error" inowanikwa kuburikidza nekugadzira "vector synthesis" yezvikanganiso zvese zve "space point".
Kunyatsojeka kweCMM kunoda kutarisirwa zvakanyanya, uye ine zvikamu zvakawanda uye chimiro chakaoma, uye zvinhu zvakawanda zvinokanganisa kukanganisa kwekuyera. Kune manyuko mana makuru ezvikanganiso zvisingachinji mumichina ine axis dzakawanda seCMMs seanotevera.
(1) Kukanganisa kwejometri kunokonzerwa nekusanyatsojeka kwezvikamu zvechivakwa (zvakadai semagwara nemasisitimu ekuyera). Kukanganisa uku kunoenderana nekunyatsogadzirwa kwezvikamu izvi zvechivakwa uye kunyatsogadziriswa kwekugadzirisa pakuiswa nekugadzirisa.
(2) Zvikanganiso zvine chekuita nekuomarara kwezvikamu zveCMM. Zvinonyanya kukonzerwa nehuremu hwezvikamu zvinofamba. Zvikanganiso izvi zvinotsanangurwa nekuomarara kwezvikamu zvechimiro, huremu hwazvo uye magadzirirwo azvo.
(3) Zvikanganiso zvekupisa, zvakaita sekuwedzera nekukotama kwegwara rinotungamira rinokonzerwa nekuchinja kwekupisa kamwe chete uye magiradhi ekupisa. Zvikanganiso izvi zvinotsanangurwa nechimiro chemuchina, hunhu hwezvinhu uye kugoverwa kwekupisa kweCMM uye zvinokanganiswa nezvinobva kunze kwekupisa (semuenzaniso tembiricha yemhepo) uye zvinobva mukati mekupisa (semuenzaniso unit yekutyaira).
(4) zvikanganiso zveprobe uye zvekushongedza, zvinosanganisira shanduko mu radius yemugumo weprobe zvinokonzerwa nekutsiviwa kweprobe, kuwedzerwa kwetsvimbo refu, kuwedzerwa kwezvimwe zvekushongedza; kukanganisa kweanisotropic apo probe inobata chiyero munzira dzakasiyana nenzvimbo; kukanganisa kunokonzerwa nekutenderera kwetafura yekurongedza.
