Ntugharị agbagharịbụ akụkụ ndị na-akwado ogwe nke mgbapụta gia, na nfuli ihe eji eme ihe na-eji agbagharị agbagharị agbagharị agbagharị agbagharị agbagharị agbagharị nke ogwe mgbapụta. Ogo nke igwe na-atụgharị ga-emetụta kpọmkwem ntụgharị ntụgharị nke mgbapụta ahụ. Ya mere, mgbe a na-edobe ma na-echekwa mgbapụta gia, a ga-eji nlezianya nyochaa ihe na-ebugharị ya.

Mgbe ị na-enyocha ebe a na-atụgharị mpịakọta, akụkụ ndị a kwesịrị ịmalite:

1. Nyochaa ihe ndị na-agbagharị agbagharị. Mgbeibugharị ibuna-ehicha ya, ihe niile mejupụtara kwesịrị iji nlezianya nyochaa. Dịka ọmụmaatụ, ma enwere mgbanaka n'ime na mpụta mgbanaka nke ebu, ma enwere ntụpọ n'okporo ụzọ mgbanaka nke ime na mpụta, ma enwere ntụpọ na ihe ndị na-agbagharị agbagharị, ma enwere ntụpọ na nrụrụ ndakpọ na ọnụ ụlọ, na ma ọ na-ekpo oke ọkụ n'ụzọ ime na mpụta. N'ebe enwere ngbanwe na mgbanaka, ma mgbanaka ime na n'èzí na-atụgharị nke ọma na n'efu, wdg. Ọ bụrụ na achọpụtara ntụpọ ọ bụla, a ga-eji ihe ntụgharị ọhụrụ dochie ha.

2. Lelee mkpochapụ axial. Mkpebi axial nkeibugharị ibuna-etolite n'oge usoro mmepụta ihe. Nke a bụ mkpochapụ izizi nke igwe mpịakọta. Otú ọ dị, mgbe oge a na-eji ya eme ihe, nkwụsịtụ a ga-abawanye, nke ga-emebi ngbanwe ntụgharị nke ihe eji eme ya. Ekwesịrị ịlele oghere ahụ.

3. Nyocha radial. Usoro nyocha nke nkwụsị nke radial nke ihe na-agbagharị agbagharị yiri nke nkwụsị axial. N'otu oge ahụ, radial size nke na-agbagharị agbagharị nwere ike isi kpee ikpe site na nha nke mkpochapụ axial ya. N'ikwu okwu n'ozuzu, ihe na-akpụ akpụ nwere nnukwu mkpochapụ axial nwere nnukwu mkpochapụ radial.

4. Nyocha na nha nke oghere na-ebu. Oghere na-ebufe nke ahụ mgbapụta ahụ na-eme mgbanwe mgbanwe na mgbanaka dị n'èzí nke ihe na-atụgharị. Nkwenye kwesịrị ekwesị n'etiti ha bụ 0 ~ 0.02mm. Mgbe arụchara ọrụ ogologo oge, lelee ma oghere nke na-ebu ya agwụla yana ma nha abawanyela. Iji mezuo nke a, enwere ike tụọ dayameta dị n'ime nke oghere na-ebu ya na vernier caliper ma ọ bụ micrometer nke dị n'ime, wee jiri ya tụnyere nha mbụ iji chọpụta ọnụọgụ nke uwe. Na mgbakwunye, lelee ma enwere ntụpọ dị ka mgbawa n'elu ime oghere nke oghere. Ọ bụrụ na enwere ntụpọ, oghere na-ebu nke mgbapụta ahụ kwesịrị ka a rụzie ya tupu ejiri ya.
