High speed numerical control machine and high speed cutting technique may realize numerical manufacture in parts of spacecraft which is light material metal and thin-wall.
The first stage, the modeling process should consider the basic configuration, the interface size, material selection, structure layout, accessory drawing.
The application of CAD/CAM integrated technique in the control and display parts of spacecraft based on Pro/E Usually, 2A12 duralumin metal is used in the control and display parts of spacecraft, the construct of which is thin-wall, and mostly material will be removed together with some holes and grooves.

Introduction Today, bulk metallic nanocrystalline materials are obtained which may be used as structural elements [1].
So, it is necessary to develop fundamental investigations on physical nature of strength of these new type of materials.
Separate nanoparticle is the building blocks of bulk nanocrystalline materials.

Abstract.
The Mohr-Coulomb[1, 2] elastic-plastic model is used to model the rockmass geological materials, and the permeability model coupling to the mechanical model is based on Darcy's law.
Beam unit or entities unit with the elastic material are used to simulate molded concrete usually.

The purpose of calibration is to make different point (different assumed detectors in the detector arrays) have the same response for the same thickness of the same material.
For the same kind of material, µ has the same value, and I0 is always the same for the detection system.
The original image and calibrated image is showed in Fig.5 Figure 4 Pi curves (the horizontal axis represents the thickness, and the vertical is Pi) 5mm ABS Al 8cm ABS 5mm ABS+Al (a)Original image of three material (b)Image after calibration Figure 5 The calibration result Summary Comparing Fig.5 (a) and (b), we could find that the signal of the same thickness and the same material is uniformed.

Produce spindle shaft rotational error of the main reasons: The spindle the few paragraphs journal Coaxial error, Bearing itself various errors, Concentricity error between the bearings, Spindle around degrees.
The correct selection of tool materials and the selection of a new type of wear-resistant tool materials, a reasonable selection of tool geometry parameters and cutting parameters, coolant, can minimize the size of the tool wear.
Machine, tool and the workpiece is subject to a variety of heat sources, the temperature will gradually rise, meanwhile, they are also distributed to the surrounding material and space heat.
Can also be used insulation material will be separated from the heating member and the machine bulky.

The basic concept is that central region of the reactor core is filled with fertile (blanket) material.
During the reactor operation fissile material accumulates in this central region to compensate fissile material loss in the peripheral core region and also contributes to negative coolant loss reactivity effect.
And the core of SPINNOR surrounded by a reflector material.
