Disigning coolant channel on the firebox of liquid rocket engine to loxodrome ( equal - angle helix ) groove can improve firebox coolant capability greatly. because the width dimension of loxodrome groove is narrow and the depth is deep, some machining methods are incapable, such as end - milling or electrochemistry. according to the peculiarities, a cnc disk - cutter - milling method which is composed of five motion axes with four simultaneously interpolated ones is researched. because most firebox generatrix is composed of complex curves, it is very difficult to get cnc cutting program with manual means. in order to deal with the problem, the loxodrome mathematics model is studied, and an auto - programming software system is developed. the software system can generate cnc cutting program of loxodrome on many kinds of turned surface. the constriction - distension segment of firebox is the most representative workpiece. the sharp changing of its generatrix slope makes loxodrome milling difficult. with the theory analyzing and practice cutting experiment, some applied techniques, which include milling mode and direction, choosing cutter diameter and cutting start point setting, are developed. adopting the technology above, tens regular workpiece have been manufacturing. the two - year manufacture practice has confirmed the validity and feasibility of developed loxodrome coolant channel milling method. the developed technology is also worth to be referenced to other similar workpiece

液體火箭發動機燃燒室的冷卻通道設計為斜航線（等傾角螺旋線）槽形，可以大幅度改善燃燒室的冷卻性能.斜航線冷卻槽的槽寬尺寸較小而槽深尺寸較大，所以無法使用棒銑刀銑削、電化學等加工方式.針對這些特點，提出了五軸控制、四軸聯動的數控片銑刀銑削加工方法.由於燃燒室外表面的母線輪廓復雜，手工編制數控加工程序難度大.為了解決數控加工程序的編制問題，研究了斜航線的數學模型，開發了自動編程軟

Through field investigation, microscopic study, x - ray phase analysis and mineral infrared spectrum analysis, the authors determine the laumontitization had occurred widely in the axi gold field. according to the development of laumontitization and its relationship to mineralization, authors reveal that the laumontitization appeared mainly at the top and periphery to ore - bodies. it befallen at the edge of the geothermal fluid system or happened in the late stage of geothermal fluid system evolution, hence can be assigned as an indicator to prospect for epithermal gold deposit. the fluid causing laumontitization in the axi gold deposit is similar to those causing hot spring type gold deposit or in modern geothermal field. the fluidization of the axi gold deposit happened in carboniferous, showing the west tianshan is a good district for epithermal gold mineralization and preservation. so west tianshan is prospecting for exploring epithermal gold deposit
