Abstract. Advanced Technology is emerging now a day to minimize time and scrap which is major concern in industries. Most complexed models can be fabricating by CNC machines like turbine blades, impellers, and propellers. Recent advances in computer numerical control (CNC) machining technologies are discussed in. The blade of impeller is usually designed with a rule surface which is normally twisted in design to achieve the required performance. It can be undercut, overcut and collision problems during machining. The issues to satisfy the quality requirements, to reduce the machining time and to avoid the occurrence of collision become an integral problem. The multi-axis toolpath generation using flank milling method has been discussed for the rule surface of helical rotor. Authors discussed 5-axis machining on rule surface in. Post-processing technology is the key to CNC automatic programming technology and important module of the CAD/CAM system. The NC machining Post-Processing technology based on Siemen UG NX is explained in. Post-processing of tool path for multi-axis milling machines, generated by the CAD/CAM system is a critical activity in engineering work. The technological process is important to enter the process of manufacturing of various precision engineering components of complex shape designed for the needs of automotive and aerospace industries. 

Keywords. Integrated Approach, CAD, CAM, 4-axis Milling, Rule Surface
