Ongorora Zvakakwana Kusimbiswa kweMetrological kweCMM
CMM sisitimu yakaoma yekuyera inobatanidza tekinoroji ye optical, mechanical, electrical, computer uye control, saka pane zvinhu zvakawanda zvisina chokwadi zvinokanganisa mhedzisiro yekuyera, asi kune zvishandiso zvemuchina zvidiki nepakati, kutsauka kwekushisa kwemhepo kubva pakupisa kwakajairwa (20℃) ndicho chinhu chikuru chinokanganisa kusava nechokwadi kwekuyera. Kuti chiyero cheCMM chiite mhedzisiro chaiyo, tembiricha yemhepo inofanira kudzorwa zvakasimba mukati mehuwandu hweCMM.
1. Ko sisitimu yekuona ye Muchina wekubatanidza zvinokanganisa mhedzisiro yekuyera here?
Tinoziva kuti kana muchina wekubatanidza uchiyera, Kuferefeta inotumira chiratidzo mushure mekubata workpiece kuti iyere, uye ipapo coordinate position yeprobe inounganidzwa ne control system necomputer, uye ipapo kuverenga kwakakosha kunoitwa kuti tiwane measurements yekuyera yatinoda. Parizvino, ma probe mazhinji ane three-coordinate ari switch type, ane musimboti wekugadzira unotungamira kune akasiyana switch contact points munzvimbo dzakasiyana, izvo zvinounza detection errors. Chikanganiso ichi chinokanganisa zvakananga kusava nechokwadi kwe coordinate measurements. Saka unoda kuti coordinate position ive diki sezvinobvira.
2. Ndezvipi zvikanganiso makumi maviri nerimwe zvemakoordinati matatu?
Kune ma axes matatu ekufamba, rimwe nerimwe rine imwe positioning error uye mashanu geometric errors. Zvikanganiso zve geometric zvinosanganisira straightness errors mumativi maviri uye angular errors mumativi maviri. Kune 18 errors mu matatu axes, uye 21 errors mu verticality pakati matatu axes.
3. Zvinofanira kuitwa riini kuti tigadzirise zvikanganiso makumi maviri nerimwe?
Hwaro, kunyatsojeka uye kuyera macoordinates matatu zvakaoma. Kunyangwe zvisina kunyorwa mutsanangudzo, kukanganisa kwekugadzirisa kwe21 kunodiwa mune zvinotevera: kugamuchirwazve; Chikanganiso chekuyera hurefu Chikanganiso chemhedzisiro yekuenzanisa; Macoordinates mushure mekufamba kwemuchina; Muchina wecoordinates wagadziriswa.
4. Ndezvipi zvishandiso zvinodiwa kuti pave nekuyera macoordinates?
Mipimo inodiwa kugadzirisa macoordinates matatu ndeiyi: saizi yegiredhi rinoenderana nebhuroko rekuyera i1000mm; Laser interferometer. Electronic level; Square ruler; Standard ball, nezvimwewo.
