| Abstract: | Pertaining to the Zhaojiawan Tunnel construction, the pick arrangement on cutting head is first introduced. Through pick location encoding, classifying and on-site pick replacement, the pick replacement rules and inefficiency position partition properties are statistically investigated into UK- and Germany- made milling machines. Then, the differences of pick wear between them are attained. Finally, the recommendations are provided in terms of pick manufacturing process, selection, assembly and cutting so as to improve the pick life-cycle and milling machine performance. |
