Kupatsanurwa kweNzira dzekuyera dzeCMM

A Muchina wekuyera weCoordinate (CMM) mudziyo unoshandiswa kuyera nemazvo geometry yechinhu. Zvichienderana nenzira dzakasiyana dzekuyera, CMM inogona kukamurwa muzvikamu zvinotevera:

1. Bata Kuferefeta chishandiswa chekuyera chinoenzanisa chiyero (chinonyanya kushandiswa);

2. Chishandiso chekuyera chinoonekwa chekubatanidza zvinhu zvakasiyana-siyana;

3. Chishandiso chekuyera cheLaser composite coordinate (chinonyanya kushandiswa pakuyera chigadzirwa uye kuongorora kopi yemifananidzo).

Pakati pavo, nzira yekuyera kubata inoshandiswa pakuyera zvigadzirwa zvakagadzirwa nemuchina, zvigadzirwa zvakadzvanywa, mafirimu esimbi, nezvimwewo. Kuti uongorore data rekugadzirisa workpiece kana kupa ruzivo rwepakutanga rweworkpiece ye reverse engineering, zvinowanzodiwa kuti utarise data riri pamusoro peworkpiece iri kuyedzwa uchishandisa coordinate. Muchina wekuyera. Kushanda kweCMM pakuongorora ndekushandisa chirongwa cheDMIS kuunganidza mapoinzi edata munzvimbo chaiyo yechinhu chinofanira kuyerwa, chinogona kuva mutsetse, pamusoro, chikamu chechikamu, curve yechikamu kana mutsetse weperimeter uri kure kubva kumucheto. Chinhu chakayerwa chinoiswa munzvimbo yekuyera yecoordinate, nzvimbo yekuyera yepoinzi yega yega pachinhu chakayerwa inogona kuwanikwa, uye saizi yejometri, chimiro nenzvimbo yechinhu chakayerwa zvinogona kuverengerwa zvichienderana nehukuru hwemapoinzi aya. Nheyo huru ndeyekuwana nzvimbo yepoinzi yespatial yechinhu chakayerwa chejometri kuburikidza nekubatana kwe sensor yekuona (probe) uye kuyerwa kwekufamba kwespatial axis, uye wozopedzisa kuongorora nekugadzika mapoinzi akayerwa (mapoka emapoinzi) kuburikidza nemamwe masvomhu ekuverenga, uye pakupedzisira kudzorera chinhu chakayerwa chejometri, uye kuverenga kutsauka pakati pacho ne theoretical value (nominal value) zvichienderana neizvi. Saka pedzisa kuongorora zvikamu zviri kuyedzwa.

Kushandisa CMM nemazvo kunofanira kutarisisa zvinhu zvinotevera:

(1) Usati wagadzirisa workpiece, probe inofanira kudzoserwa kunzvimbo yainobva coordinate kuti ichengete nzvimbo yakakura yekugadzirisa; Kusimudza workpiece kunofanira kunge kwakapfava, uye hakugone kukanganisa chero chikamu che CMM.

(2) Isa zvikamu nemazvo, uye iva nechokwadi chekuti zvinodiwa nezvikamu nemuchina wekuyera zvinosangana nezvinodiwa nemuviri usati waisa.

(3) Gadzira sisitimu yekuronga zvinhu chaiyo kuti ive nechokwadi chekuti sisitimu yekuronga zvinhu yakavakwa inosangana nezvinodiwa nemifananidzo kuitira kuti ive nechokwadi chekuti data rakayerwa rakarurama.

(4) Kana purogiramu yacho yatanga otomatiki, zvakakosha kudzivirira kukanganiswa pakati peprobe nechinhu chebasa, saka zvakakosha kungwarira kuwedzera inflection point.
