Emkhakheni wokukhiqiza osezingeni eliphezulu, isisekelo sokunemba siyisisekelo sangempela. Kungakhathaliseki ukuthi kumshini wokulinganisa ohlanganisiwe (i-CMM), isiteshi sokuhlola se-semiconductor, noma umugqa wokuhlanganisa onembile, ukukhethwa kwezinto zokwakha isisekelo noma i-fixture kunquma ukuzinza, ukunemba, kanye nobude benqubo.
Kubaphathi Bokulawula Ikhwalithi kanye nabenzi bezinqumo zokuthengwa kwempahla, ukukhetha akusekho phakathi kwensimbi ne-granite kuphela. Izinto ezithuthukisiwe ezifana ne-Precision Ceramics kanye ne-Carbon Fiber Composites sezingene enkundleni.
Lo mhlahlandlela unikeza ukuqhathanisa okuphelele kwezinto zepulatifomu ngokunemba ukuze kukusize uqonde umehluko phakathi kwezindleko, ukusebenza, kanye nezidingo zohlelo lokusebenza.
Abaqhudelanayo: Amaphrofayili Ezinto Ezibalulekile
Ukuze senze isinqumo esinolwazi, kumelwe siqale siqonde izici zomzimba zezinto ezintathu ezivelele ku-metrology yesimanje.
1. I-Granite: Izinga Elizinzile
I-granite ibilokhu iyindinganiso embonini amashumi eminyaka, futhi ngesizathu esihle. Iyinto yemvelo eye yadlula iminyaka eminingi "yokuguga kwemvelo," okusho ukuthi ukucindezeleka kwayo kwangaphakathi akusekho nhlobo.

- Inzuzo Eyinhloko: Ukunciphisa ukudlidliza okumangalisayo kanye nokuqina kokushisa.
- Okuhle Kakhulu: Ukulinganisa okunembe kakhulu kanye nezisekelo ezisindayo.
2. I-Precision Ceramic: Uchwepheshe Oqinile Kakhulu
Ngokuvamile zenziwe nge-Alumina (Al₂O₃) noma i-Silicon Carbide, izitsha zobumba ezinembile zenzelwe ukuqina okukhulu. Njengoba i-modulus enwebekayo ifinyelela ku-300-400 GPa (uma kuqhathaniswa ne-~70 GPa ye-aluminium noma i-granite), izitsha zobumba zinikeza ukuguqulwa okucishe kube yi-zero ngaphansi komthwalo.

- Inzuzo Eyinhloko: Ukunciphisa isisindo esikhulu ngaphandle kokulahlekelwa ubuqotho besakhiwo.
- Okuhle Kakhulu Kulokhu: Ukuzenzakalela okusheshayo, izinto ezisebenza ngamarobhothi, kanye nezinto zokulungisa izindiza.
I-Matrix Yokuqhathanisa
Uma kuhlolwa ukukhethwa kwesisekelo se-metrology, kubalulekile ukubheka izilinganiso ezithile zokusebenza. Ithebula elingezansi liqhathanisa lezi zinto nezinto ezibalulekile zokukhiqiza.

Ukucwila Okujulile: Ukusebenza vs. Ukusetshenziswa
I-Granite: Inkosi Yokuzinza
I-Granite ihlala iyisinqumo esiphezulu sezinhlelo zokusebenza ezingashintshi lapho ukudambisa ukudlidliza kubalulekile khona. Isakhiwo sayo semvelo simunca amandla kunokuba siwadlulisele, okubalulekile ekuqedeni ubuso kanye nokuphindaphinda kokulinganisa. Ngaphezu kwalokho, i-granite ayisebenzi ngamakhemikhali futhi ayigqwali, okwenza ifaneleke kakhulu ezindaweni eziqinile zesitolo.
