The rock fracturing during waterjet cutting is very complicated because rock is inhomogeneous and anisotropic, compared with artificial materials (e.g., metal or glass). Thus, it is very important to verify the effects of rock properties on waterjet rock cutting performance. Properties affecting the...

초고압 워터젯은 어떤 경우에 사용되었는가? | 초고압 워터젯을 이용한 절삭기술은 파쇄가 일어나는 재료 주변의 추가적인 응력과 열을 발생시키지 않는다. 이러한 장점으로 기존 워터젯 기술은 금속, 유리, 세라믹과 같은 공장규모에서 재료가공을 위해 주로 사용되었다. 특히 암반을 다루는 것에 있어 원하는 형태로 절삭이 가능하고 암종과 물성에 따른 시스템(특히 노즐) 교체가 불필요하기 때문에 토목 및 자원 개발 적용시 큰 장점으로 작용된다. 최근 초고압 워터젯 시스템이 암석절삭이나 천공에 활발히 활용되면서 터널시공과 관련된 다양한 연구가 수행중이다. | |

워터젯은 연마재의 사용 유무에 따라 어떻게 나눌 수 있는가? | 워터젯은 연마재의 사용 유무에 따라 순수 워터젯(plain waterjet)과 연마재 워터젯(abrasive waterjet)으로 나눌 수 있다. 순수 워터젯은 1972년 초고압 펌프가 개발되어 산업현장에 사용되면서 처음으로 알려졌다(Summers 1995). |
