Pro/Engineer software parametric famous parametric technology, is the earliest application, present in the3D modeling software plays an important role in the field of CAD/CAE/CAM, Pro/Engineer as the new standard has been recognized by the industry and the promotion of. Is the current mainstream CAD/CAM/CAE software, especially in the field of product design to occupy an important position. Pro/E first put forward the concept of parametric design, and uses a single database to solve the related problems. In addition, it uses the modular approach, the user can according to their own needs to choose, without having to install all module. Based on the characteristics of Pro/E mode, be able to design and production of the entire process of integrated together, the realization of parallel engineering design. It not only can be applied to the station, but also can be applied to a single. Pro/E adopts module, each sketch, parts production, assembly design, sheet metal design, processing, to ensure that users can choose to use according to their needs. Computer simulation technique is the application of computer on the system s mathematical model, to study the actual system operation performance technology, the computer simulation is the application of computer mathematical models in the experiments, and the experimental comparison with real objects, with the economy, security, and other characteristics of the short experimental period. Machine tool manufacturing industry is the basic industry of other mechanical processing industry, machine tool for other mechanical products manufacturing base, as the master the importance of the role is fresh and easy to see. In the machine tool design and manufacture process of introducing simulation technology can greatly shorten the development cycle, reduce machine tool machine tool research and development costs, improve the reliability of the machine tool. Based on a simplified machine from model, assembly, machine tool motion simulation, analysis of the entire process, the simulation technology in the machine tool industry machine application in design process. 1 Introduction Technology is a computer simulation system mathematical model, study the actual application system running technique, computer simulation and application, because the computer experimental mathematical models, but also economic, safety, testing the physical experimental short cycle. Machine tool as the other machine foundation, makes the other processing machine tool manufacturing industry is the industrys development, but also as a mother ship the importance of the effect is obviously. In mechanical design and operation process simulation technology is introduced into the can greatly shorten the development cycle for the machine tool research and development costs, improve the reliability of the machine. CNC machine tool main axle box mainly comprises a motor, drive system and spindle components, mainly used to achieve the main campaign tool, it should have a certain speed and the speed range, in order to use different material cutting tools, processing materials, different sizes, different requirements, and can conveniently realize the machine start and stop, change speed, direction and brake etc. Mechanism motion simulation mainly comprises a body connected, add drive, motion simulation and analysis of results of four process, to ensure the formation of can exercise, assembly can not be locked, but according to the various components of the motion and the relative motion, through various connection setting, to limit the motion of components free state. On the set after connecting to the setting mechanism motion device, mainly including setting motion device name and distribution map. Distribution map of position, velocity and acceleration of three specifications, specifications of each type can be set up to eight different equation, and can be realistic graph of an equation. 2 machine molding, assembly, simulation, and analysis 2.1 tool, designed to identify: Assuming that the machine function, realization of thread processing 2.2 design of target analysis Machine tool to realize thread processing, requires the main campaign tool and workpiece feed portion having a defined transmission relation, 1 =1 S = S97U97T1( spindle ) - from spindle to screw the total transmission ratio: T1 machine screw thread lead ( for example: CA6140general machine tools T1= 12 mm )； S - is the lead of the thread processing； From the above equation, changes to the U can access various thread. Finally, the machine tool model can be simplified to Gear, worm gear, rack and pinion drive group； by setting the gear parameters, the U value；The parameter T1by a worm drive, gear drive group together to achieve, can also be by the screw nut group also realized, this paper adopts the former. Soft3computer simulation technology is a computer application of the model, to solve the system, and to study the operation of technical performance, computer simulation applications, because the computer mathematical model experiment, experimental comparison of types, and economic, safe experimental short cycle. Pro / ENGINEER as an integrated CAD / CAM / CAE / PDM engineering software,3D modeling ability is very strong, the mechanism of the module also has a sports / dynamics simulation, dynamic, static, balance of power, simulation, analysis ability and to provide a mechanism for moreKind various body means to carry out linkage, cam, gear, gear, screw mechanism, such as the complexity of the simulation and analysis of various institutions. 2.3 design 2.3.1 modeling The use of Pro / E from the formula of tooth profile of involute equation method is applied to obtain the model Involute gear design is the formula for: Converted to Pro / E formula: =DB/ 2 Theta =9745 tons X = R * cos () +sin () * - * pi/180 X = R * sin () -cos () * - * pi/180 Z = 0 After a model can be used for Pro / E design function parameters in different size gear to build relationship, so, the same can be achieved through a gear types, depending on the size of the gear modeling. Matching gear, just change it parameters can be completed in numerical simulation. Worm, worm gear, modeling and modeling steps of rack gears are basically the same, only the worm gear, worm, rack tooth profile equation of spur gear used is different. Worm gear tooth profile equation: R = D5/ 2 = t * 45 X = R * cos () + sin () * - * pi/180 X = R * sin () - cos () * - * pi/180 Z = m * q / 2 Worm tooth profile equation: 1) spiral: R = m * q / 2 = t * TX *360 Z = t * La 2) involute equation: R= D4/ 2 =t*60 X=r*cos () +sin () * *pi/180 X=r*sin () -cos () * *pi/180 Z=0 Rack continuously trapezoidal profile, is a simple profile without the establishment of equation. In this regard, various functional components, to achieve the machine model. 2.3.2 assembly, simulation, and analysis First of all in the Pro / E module assembly, and then transferred to Pro / mechanism simulation and analysis, along with the more and more complicated mechanism may be more mistakes, so the use of some new assembly simulation, analysis, simulation, data analysis is complete, the new parts, and then analysis, simulation method gradually by part to the overall implementation of the correct establishment of machine tool model. In Pro / mechanism analysis of measurable quantities : the position, velocity, acceleration, connected to the reactor, the momentum of net load. I n Pro / mechanism to measure the parameters of the model to measure the different sports, if not satisfied, then to build up a new model, simulation, analysis and the model again to meet the design requirements. Through the analysis, in order to improve the further simulation, and comply with the design requirements of perfect function, eventually forming a part of the prototype, the results of simulation. 3 virtual NC machine tools have the characteristics of: 3.1 good structure Good structure includes three aspects. 3.1.1 and real machine tool structural similarity.
