(1) Pohaku wili palaoa

Hoʻopili ʻia ka hana o ka whetstone e ka hoʻokumu ʻana (resin, filler, abrasive, etc.), ka hana hoʻoheheʻe ʻana (mixing, curing, etc.), structure (porosity and pore size, abrasive concentration, etc.), a me nā pilina heterogeneous (resin/abrasive, resin/filler, etc. I kēia manawa, ʻaʻole maopopo ke ʻano o ka hoʻopaʻa ʻana o ke ʻano o ka ʻōnaehana abrasive; ʻO ka micro/nano filler ma ka paʻa paʻa, ka pale ʻana i ka wela, ka pale ʻana o ke ʻano hoʻoponopono pono e hōʻike ʻia; paʻakikī pōhaku abrasive hale o ka physical a me ka kemikala waiwai o ka abrasive pohaku, ka hana o ka hopena o ka hana o ka hana lawelawe i keia wa maopopo ole. ʻO nā pilikia ʻepekema a me nā ʻenehana i luna e lawe mai i nā pilikia nui i ka hoʻoponopono ʻana i ka hana o nā pōhaku wili.

Ua hoʻohana ʻo Yuan Yongjie [1] iā Abaqus a me Python no ka hoʻokumu ʻana i kahi kŘkohu wili pōhaku, a hana i ka noiʻi pili i ka wili pōhaku ma o ke ʻano o ka helu ʻana i ka element finite, he mea hoʻoikaika koʻikoʻi ia no ka hoʻolālā ʻana i nā pōhaku wili me nā ʻano like ʻole a me nā kaʻina hana paʻakikī. No laila, i ka wā e hiki mai ana, hiki iā mākou ke hoʻohana i ka mea pau ʻole a me nā ʻano hana ʻē aʻe e kūkulu i ke kumu wili pōhaku me ka wikiwiki a me ka maikaʻi, a hoʻokumu i kahi kikoʻī ʻoi aku ka maikaʻi o ka pilina pane synergistic ma waena o nā kumu like ʻole e alakaʻi i ka hoʻolālā ʻana o nā pōhaku wili. A ua hoʻāpono ʻia ke kumu hoʻohālike e ka nui o nā ʻikepili hoʻokolohua kumu.

(2) Pohaku abrasive/rail interface hana

Abrasive geometry, spatial orientation i randomness, ka hopena i ka nui okoa ma ka mua kihi o ka abrasive wili (paheʻe, palau, oki) kaʻina hana, a pela ke kuleana o kela a me keia abrasive ma luna o ke kaʻaahi 'ano hana (mechanical ikaika, wili wela, etc.) no hoi random, a no laila, aia nā ʻokoʻa i ka hemahema o ka ili o ka pōhaku, ka hopena o ka maikaʻi o ka pōhaku. ʻO ke kūpono: ʻo ka abrasive ma hope o nā pōʻai he nui o ka abrasion - hoʻomaʻamaʻa ponoʻī, hāʻawi i ka pāʻani piha i kāna hana ʻoki; ʻaʻahu paʻa a hoʻoheheʻe ʻia, no laila e hoʻoneʻe ka passivated abrasive, ʻo ka pōhaku wili iā ia iho; akā, ʻoi aku ka nui o ka ʻaʻahu o ka mea paʻa, e hopena i ka hoʻokahe ʻana o ka abrasive, abrasive utilization rate ua hoʻemi ʻia, hoʻemi ʻia ke kūpaʻa abrasive o ka pōhaku wili, e pōkole ke ola lawelawe. No laila, ʻo ka ʻaʻahu a me ka hoʻomaʻamaʻa ponoʻī o ka pōhaku wili e pono e hōʻea i kahi kūlana kaulike, i mea e hana ai ka pōhaku wili i ka hana ʻoki ikaika a me ke ola lawelawe lōʻihi. I ka manawa like, pili pono ka ʻaʻahu o ka pōhaku wili i ke kūlana abrasive a me ka ʻoki ʻoki ʻana, ʻo ia hoʻi ka hopena i ke kaʻina wili ʻana i ka wela a me ka maikaʻi o ka ili. No laila, hiki ke ʻike ʻia i ke kaʻina o ka wili ʻana i ke kaʻaahi, ma lalo o ka hoʻohui ʻana i ka thermal-mechanical o ka wili pōhaku / rail interface, ʻo ka wehe ʻana o nā mea a me ka hiki ʻole o ka wili pōhaku e pili kekahi i kekahi a loaʻa kahi pilina pili, e hoʻopili ai i ka maikaʻi o ka ʻili o ke kaʻa ma hope o ka wili ʻana.

I kēia manawa, ʻaʻole maopopo ke ʻano hana ma waena o ka wehe ʻana i nā mea a me ka hāʻule ʻana o ka pōhaku ʻala i ke kaʻina wili kaʻaahi a me kona hopena i ka maikaʻi o ka ʻili o ke kaʻaahi, kahi e hoʻonui ai i ka paʻakikī o ka hoʻolālā ʻana o ka pōhaku ʻala, e like me ka hōʻike ʻana ma ka Fig. 1(b). No laila, he mea nui e aʻo i ke ʻano o ka wehe ʻana i nā mea i ka wā o ka wili ʻana o ke kaʻaahi, ka hana ʻana o ka pōhaku ʻala, ka hoʻomohala ʻana o ka maikaʻi o ke kaʻaahi, a me ke kūkulu ʻana i ke ʻano pili kino o ke ʻano o ka pōhaku whetstone - nā waiwai mechanical o ka pōhaku ʻala - ka hana wili ʻana - ka hana hemahema o ka pōhaku - ka maikaʻi o ka ʻili o ke kaʻa, he waiwai nui ia no ka hoʻolālā ʻana a me ka hana ʻana i ka pōhaku ʻala.

(3) Ka loiloi o ka hana pōhaku wili

ʻO ka loiloi ʻepekema a piha i ka hana ʻana i ka pōhaku wili (ʻoi aku ka hiki ke wili ʻia), ka ʻano pōhaku wili, ka hoʻolālā kaʻina hana he kuhikuhi koʻikoʻi. I kēia manawa, aia nā ʻano hana like ʻole no ka loiloi ʻana i ka hana ʻana o ka pōhaku ʻala, a ʻaʻole i lawa nā kūlana loiloi like ʻole no ka hana ʻana o ka pōhaku ʻala, kahi mea paʻakikī ke kaʻana ʻana i nā hopena noiʻi e pili ana i ka pōhaku ʻala, e like me ka mea i hōʻike ʻia ma ka Fig. 1 (c). I kēia manawa, nui ka poʻe noiʻi e hana i nā noiʻi e pili ana i ka hoʻomākaukau ʻana i nā pōhaku wili piha, he nui ka nui, ʻaʻole kūpono i ka macro / micro characterization a me ka nānā ʻana, ʻaʻole hiki ke loaʻa i ka ʻikepili hoʻokolohua ʻoi aku ka maikaʻi, e hopena i nā hopena hoʻokolohua o nā wili palaoa me ke alakaʻi palena ʻole i ka hoʻoponopono ʻana i ka hana o ka wili, e hōʻemi ana i ka noiʻi a me ka hoʻomohala ʻana i ka hopena o ka wili, hoʻonui i ka noiʻi a me ka hoʻomohala ʻana i nā hopena o ka wili, a me nā mea maka. No laila, hiki ke hoʻohana ʻia kahi ala ʻenehana loiloi multi-dimensional e hoʻolālā ʻepekema i ka mīkini loiloi pōhaku a kūkulu i nā alakaʻi loiloi no ka hana ʻana i nā pōhaku wili i nā ʻano like ʻole, i mea e kau ai i ke kumu no ka hoʻolaha ʻana i nā pōhaku wili i nā laina kaʻaahi.
