ʻO ke ākea puka liʻiliʻi, ka nānā nui - e hōʻike ana i ka mea pohihihi o ka "hole spacing" i ka hana mechanical

Ma ke ola o kēlā me kēia lā, mai nā puka wili kelepona liʻiliʻi a i nā hale kila alahaka nui, ʻo ka hui ʻana o nā huahana he nui i hilinaʻi ʻia i ka "wāwae puka". ʻO kēia ʻāpana maʻalahi kekahi o nā pōhaku kihi o ka ʻoihana hou. He aha ka hole spacing? No ke aha he mea nui ia? I kēia lā, e hōʻike mākou i nā loina ʻepekema ma hope o kēia kikoʻī loea.

He aha ka hole spacing?
E like me ka hōʻike ʻana o ka inoa, pili ka hole spacing i ka mamao ma waena o nā kikowaena o nā lua ʻelua. I ka hana mechanical, pili pono ia i ka pololei o ka hui ana o na hapa. No ka laʻana, inā ʻaʻohe 0.1 mm ka mamao o ka puka wili o kahi pahu kelepona paʻa, hiki ʻole iā ia ke hoʻopaʻa; a inā ʻoi aku ka hewa o ka hoʻokaʻawale ʻana o ka lua o ka pahu pahu pahu kaʻa kaʻa i ka palena, hiki paha ke hoʻoheheʻe ʻia ka aila a i ʻole ke komo ʻana o kekahi hapa.

ʻO ka pololei o ka hoʻokaʻawale ʻana o nā puka: he lele mai nā millimeters a i nā microns
Me ka holomua o ka ʻoihana, ʻoi aku ka paʻakikī o nā koi no ka pololei o ka hole spacing:

Nā ʻāpana maʻamau (e like me nā lako hale): ʻo ka hoʻomanawanui ʻana o ka puka ma kahi o ±0.5 mm;

Nā mea hana pololei (e like me nā lens kamera): pono e hoʻomalu ʻia i loko o ±0.02 mm;

Aerospace (e like me nā pahu wahie rocket): ʻoi aku ke kiʻekiʻe o nā koi i ± 0.005 mm, e like me ka hapaʻumi o ka lauoho.

No ka hoʻokō ʻana i kēlā pololei, pono ia e hilinaʻi i nā mīkini mīkini CNC kiʻekiʻe, nā mea ana laser a me nā mea hana ʻē aʻe, a noʻonoʻo i nā mea e like me ka hoʻonui ʻana i ka wela a me ka hoʻopaʻa ʻana o nā mea a me ka vibration.

Pehea e ana i ka mamao o ka puka?

Loaʻa nā ʻano hana maʻamau:

Vernier caliper: kūpono no nā hiʻohiʻona haʻahaʻa haʻahaʻa;

ʻEkolu mīkini ana ʻana: hoʻohua i nā hiʻohiʻona 3D ma o ka ʻimi ʻimi ʻana, me ka pololei a hiki i ka pae micron;

Optical imager: hoʻohana i ka pahupaʻikiʻi e ʻike maʻalahi i nā kūlana puka, kūpono a pili ʻole.

Nā ʻano o ka wā e hiki mai ana: ka naʻauao a me ka standardization
Me ka hoʻomohala ʻana o ka ʻOihana 4.0, hoʻohana nā hale hana akamai i nā mea ʻike e nānā i nā hoʻokaʻawale ʻana o ka lua i ka manawa maoli a hoʻoponopono maʻalahi i nā ʻāpana hana. Eia kekahi, ke hoʻolaha nei ka International Organization for Standardization (ISO) i ka hui ʻana o nā kūlana hole spacing honua e hōʻemi i nā pilikia pili i nā kaulahao lako cross-border.

ʻOiai ka liʻiliʻi o ka hole spacing, he laʻana maʻamau ia o "hiki i kahi hewa liʻiliʻi ke alakaʻi i kahi hewa nui". Mai ka hoʻonoho ʻana i nā lua pōhaku i loko o nā pyramids kahiko o ʻAigupita a hiki i ka pae nano-level alignment o nā mīkini lithography chip hou, ʻaʻole i pau nā kānaka i ka ʻimi pololei. Malia paha i ka manawa aʻe e hoʻopaʻa ai ʻoe i kahi wīwī, e kanikau pū ʻoe i ke kaumaha ʻenehana o kēia wahi puka liʻiliʻi.
