Research On High Efficiency Vibration Cutting Technology Of Workpiece Vibration

In a new era of the 21 st century,high accuracy and high surface quality of parts manufacturing,become to measure a country an important index of manufacturing industry level,especially in the field of harsh environment,such as space,deep sea.In the process of the machining of all the machinery manufacturing occupies very large proportion.In ordinary cutting,cutting when done by cutting tool,workpiece relative motion,in essence is a mutual extrusion,by elastic deformation and plastic deformation to complete the process.At the same time,because of this extrusion bring large friction,which inevitably makes cutting load is big,serious harmful phenomena such as heat loss.The traditional way can not to overcome those problem.So the new machining technology,improving the mechanical parts processing precision and efficiency,from the root up the quest to reduce cutting load and the method of cutting heat is very important.Vibration cutting is add vibration to ordinary cutting.Although vibration cutting has been used in every field,but no one for deep cognitive of its nature,most of research just stay on the surface phenomenon,especially in this paper for the metal band sawing machine cutting processing industry,due to the particularity of the machining process,cutting tool circular motion,research very little,.therefore,the introduction of the concept of vibration cutting,improve the efficiency of cutting processing,study effective vibration cutting technology is very necessary.This paper mainly adopts the traditional cutting load model and the vibration parameters are introduced to new load model simulation comparison,at the same time,through the combination of hardware and software testing,processing,analysis of cutting parameters,for efficient vibration sawing technology parameter selection provides a realistic basis.In this paper,the main work and achievements are as follows:(1)In view of the metal band sawing sawing process,analyzes the cutting principle,respectively,for the average vibration sawing and sawing sawing process were analyzed,and the cutting load model is set up.(2)It is a highly effective vibration cutting vibration system overall design,first introduced the composition and working principle of metal cutting band saw machine system and then introduces the working principle and performance indexes of the vibration system,emphasizes the electrical control system design.(3)It is a metal band sawing machine cutting load experiment,load data acquisition system is designed and contrast experiment scheme,metal band sawing machine key parameters of the experimental data processing and analysis,for the average cutting load and vibration cutting load experiment result analysis,cross comparison related experimental results,are used to verify the effectiveness of vibration cutting load model,and to introduce the vibration cutting metal band sawing machine cutting system provides the reference and proved that the metal band sawing machine vibration cutting efficiency.(4)The summary of the final simulation analysis and experimental results,and found problems in the experimental research in the improved method is proposed.In this paper,the vibration factor with the traditional cutting load model coupling,a new vibration model of the load.At the same time to design a kind of workpiece vibration cutting system,use the net cutting time ratio and cutting tool and machining relative velocity to measure vibration-three independent factors: vibration frequency,vibration amplitude and the effects of cutting speed on average load.The results of the analysis are summarized,and the next step research work were discussed.
