Ke ʻano hana o ka lihi i kaomi ʻia
1. Ke kuʻi ʻia ka lihi
Ke ʻano o ke kaomi ʻana i ka lihi make i ka manawa hoʻokahi：E pelu mua i ka pā i 30 degere me ka pahi pelu 30 degere, a laila e hoʻopālahalaha i ka lihi pelu.
2. Kūlou 180 kekelē:
Ke ʻano kulou 180 degere: E pelu mua i ka pā i 30 degere me ka pahi kulou 30 degere, a laila e hoʻopālahalaha i ka lihi kulou, a laila e huki i waho i ka pā hope.
Ka palena o ka lihi make
a) Pono e pelu ʻia ka lihi make i ʻelua manawa. ʻO ka mua, e pelu i 30 ° ~ 45 ° me ka pahi ʻoi 30 ° a me kahi V-groove hohonu, a laila e kaomi palahalaha me kahi make pālahalaha. ʻO ka laulā o ka lihi make me nā mānoanoa mea like ʻole: 0.5 < T < 2.0
b) Pili ka lōʻihi (L) o ka lihi i kaomi ʻia i ka mānoanoa o ka mea a me ka hohonu hoʻokomo V groove. Ke 0.5 < T ≤ 1.5, koho ʻia ke awāwa hoʻokomo V6, a ʻo L min > 5T + R (L min > 6); Ke 2.0 ＜ T < 2.5, koho iā V10 e hoʻokomo i ke awāwa hohonu, L min ≥ 5T + R (L min > 9); ʻO ka lōʻihi make make L max o nā mea ʻelua i luna he ≤ 14mm.
c) ʻO ka lōʻihi L o ka lihi make i kaomi ʻia ma hope o ke kūlou ʻana i hope ua kaupalena ʻia e ka hohonu hoʻokomo V groove, L min ≥ 11mm
d) ʻAʻole pono e liʻiliʻi loa ka mamao mai ka lua make a i ka lihi kūlou, inā ʻaʻole e hoʻololi ʻia ke ʻano o ka lua e ka loli o ke kihi i ka wā e kūlou ana: l1min > 0.7V
