Key Technology of 5-Axis NC Programming and High-speed Milling for Integral Impellers Based on the General Software UG Junmin Xiao1, a, Changming Zhao1, b 1Department of Mechanical Engineering, Zhongshan Polytechnic, Zhongshan 528404, China axiaojunmin517@163.com, b Changming1126@yahoo.com.cn Keywords: Integral impellers, High-speed milling, NC machining, 5-Axis NC programming, CAM, UG Abstract.
So it is very difficult for ordinary engineering technicians to make qualified integral impellers by using the general NC programming software, and in order to obtain reasonable 5-axis tool path ordinary engineering technicians must solve three critical technical problems, these problems were as follows: tool path generation of blade surface, tool path generation of hub surface and technology parameters optimization of finishing.
The integral impeller as shown in Fig.1 constitutes with blades and hub, whose material is 6061 aluminum alloy.
Arrow 1 as shown in Fig.4 should be selected as cutting direction, and Arrow 2 as shown in Fig.4 should be selected as material direction.

It indicated that: (1)The geological environment problems are complex and diverse, and the treatment projects involve a multi-disciplinary cross which are environmental geology, ecology geology, geotechnical engineering, environmental engineering and landscape works.
Technique engineering methods can solve the above mine geological environment problems, especially the feasibility control and prevention of the dominant factors.
The site condition should be considered about the foundation, building materials, climate and plant species to meet the local requirements.
The specific measure includes risk rock sweeping, slope cutting, levelling slope surface, anchoring, draining, sight-viewing engineering and carving etc.
Design of the treatment projects are shown in Fig.2: Figure 2 Design of the treatment projects Conclusions The geological environment problems are complex and diverse, and the treatment projects involve a multi-disciplinary cross which is environmental geology, ecology geology, geotechnical engineering, environmental engineering and landscape works.

Among the radar absorbing materials, the thin and light materials with wide absrobing band and good absorbing ability are the objectives of the researchers who have achieved these by adopting different methods[1].
Applying frequency selective surface to the absorbing materials is one of the methods[2-4].
The results show that all the FSS units have great influence on the absorbing materials.
