Five Axis

The structure of five axis machine tool is complex and expensive, especially in the processing of complex and sophisticated parts. It is prone to produce the phenomenon of overcutting or undercutting between the machine parts and the knives or the machine tool , which will cause serious damage or even grievous scrap on the machine tool . With the help of VERICUT 7.0 Simulation of NC machine tool, you can modify and optimize the NC program code, shortening the real processing time required and improving the economic benefit of the company remarkably.

In terms of the realization for high accurate and effective machining of complicated shape having under cut shape and free formed surface, five axis controlled machine tools become indispensable because they have any tool position and attitude to avoid the collision between machine tool elements and work piece. In order to estimate the motion accuracy of NC machine tool, various kinds of certificate methods like circular cone cutting test prescribed with NAS and DBB method using the circular motion have been developed and standardized. These methods are mainly used for the motion testing of three-axis NC machine tools and therefore new method and measuring equipment for five-axis NC machine tool is needed. This study aims at developing the motion accuracy measurement system which can measure various kinds of motions like linier motion, circular motion and continuous curved motion under simultaneous five-axis controlling and establishing the compensate method of tool motion. Consideration is added from the viewpoint of motion accuracy using measurement system developed in this report in case simultaneous five-axis control motion command value from CL data.

In view of defects-"chew cutting" generated by the five-axis nc machine tool in the process of machining the S sample, the machine tool motion error model is established based on multi-body system theory. After that,combining sensitivity analysis theory with the research of machine tool processing defect causes.Then find out the main error terms which take great responsibility of machining defects and optimize related motion components,to meet accuracy requirements before leaving the factory.

During machining some ultra-intense and special-shaped parts, unstability and surface ablation often turn up. Some large and heavy parts are often machined with heavy duty NC machine tool. For avoiding the processing defects of the above parts, an online monitoring, diagnosis and control system is designed for heavy duty NC machine tool. The system can online monitor the operation condition of heavy duty NC machine tool and real-time control the processing. Some methods of signal analysis and processing are adopted such as spectrum analysis, wavelet analysis, Wigner-Ville distribution and Artificial Neural Network etc. The system is developed with C language and Qt based on Linux operation system. Optical fiber communication is adopted between industrial computer and NC system. Experiment platform of the system is machining an aircraft landing gear with five-axis NC machine tool. The scheme is verified feasible after preliminary test.
