Reseaching design improvement, completing the improvement poltfolio - Creating a simulation of its operation, learning about the principle operation of a CNC gear hobbing machine - Conducting an investigation in gear machining and gear hobbing technology, which assumed references in domestic and foreign materials - Using Inventor Professional 2015 for design, export the drawings, calculate and analyze the strength, and simulate the operation - Improving teamwork, presentation and problem - soving skills Results: + Research design improvement and manufacture tailstock of gear hobbing CNC machine + Mechanical strength check + Production drawings + Processing plan Stt.010.Mssv.BKD002ac.email.ninhd.vT.Bg.Jy.LjvT.Bg.Jy.LjvT.Bg.Jy.LjvT.Bg.Jy.LjvT.Bg.Jy.LjvT.Bg.Jy.LjvT.Bg.Jy.LjvT.Bg.Jy.LjvT.Bg.Jy.Lj.dtt@edu.gmail.com.vn.bkc19134.hmu.edu.vn.Stt.010.Mssv.BKD002ac.email.ninhddtt@edu.gmail.com.vn.bkc19134.hmu.edu.vn an VII C.vT.Bg.Jy.Lj.Tai lieu Luan vT.Bg.Jy.Lj van Luan an.vT.Bg.Jy.LjvT.Bg.Jy.LjvT.Bg.Jy.LjvT.Bg.Jy.LjvT.Bg.Jy.LjvT.Bg.Jy.LjvT.Bg.Jy.Lj Do an.Tai lieu Luan van Luan an Do an.Tai lieu Luan van Luan an Do an CONTENTS LIST OF FIGURES AND CHARTS X LIST OF TABLES XIII CHAPTER I: OVERVIEW I INTRODUCTION II ELEMENTARY THEORY OF GEAR HOBBING III ELEMANTARY THEORY OF HOBBING MACHINE IV CNC GEAR HOBBING MACHINE 11 CHAPTER II: RESEARCH SITUATION 14 I EVALUATION CRITERIA FOR GEAR: 14 II THE FACTORS AFFECTS TO THE PRECISION OF CNC MACHINE: 14 III FOREIGN RESEARCH: 14 IV DOMESTIC RESEARCH: 14 CHAPTER III: SUBJECT OF URGENCY AND SUBJECT DETERMINE 16 I SUBJECT OF URGENCY 16 II OBJECTIVES: 17 III OBJECTS AND SCOPE OF THE RESEARCH: 18 IV SUBJECT DETERMINE : 18 CHAPTER IV: OVERVIEW OF TAILSTOCK OF CNC GEAR HOBBING MACHINE19 I STRUCTURE: 19 II FUNCTION 21 III THE TAILSTOCK DEVELOPMENT PROCESS 21 CHAPTER V: ANALYSING TO SELECT THE IDEAL ALTERNATIVE DESIGN 24 I SELECTION OF THE ROTARY TABLE STRUCTURE 24 II SELECTION OF THE CENTER TAIL STOCK STRUCTURE: 29 III SELECTION OF THE FIXTURE 33 CHAPTER VI: DESIGN 38 I DESIGN THE ROTARY TABLE 39 II DESIGNING THE FIXTURES FOR CLAM AND UNCLAMP MECHANISM 43 III DESIGN ROTARY CYLINDER FOR CLAMP AND UNCLAMP MECHANISM 43 IV DESIGN HEAD OF TAILSTOCK 45 V DESIGN STRUCTURE BODY OF TAILSTOCK 46 CHAPTER VII: CALCULATE 50 I CALCULATE SHEAR FORCE OF THE KNIFE ON WORKPIECE 50 II CALCULATION OF CAPACITY FOR CONVEYING AND SELECT MOTOR FOR ROTARY TABLE 53 III CALCULATE THE BELT CONVEYOR FOR ROTARY 55 Stt.010.Mssv.BKD002ac.email.ninhd.vT.Bg.Jy.LjvT.Bg.Jy.LjvT.Bg.Jy.LjvT.Bg.Jy.LjvT.Bg.Jy.LjvT.Bg.Jy.LjvT.Bg.Jy.LjvT.Bg.Jy.LjvT.Bg.Jy.Lj.dtt@edu.gmail.com.vn.bkc19134.hmu.edu.vn.Stt.010.Mssv.BKD002ac.email.ninhddtt@edu.gmail.com.vn.bkc19134.hmu.edu.vn an VIII C.vT.Bg.Jy.Lj.Tai lieu Luan vT.Bg.Jy.Lj van Luan an.vT.Bg.Jy.LjvT.Bg.Jy.LjvT.Bg.Jy.LjvT.Bg.Jy.LjvT.Bg.Jy.LjvT.Bg.Jy.LjvT.Bg.Jy.Lj Do an.Tai lieu Luan van Luan an Do an.Tai lieu Luan van Luan an Do an  Arcoding to the caculation is shown above we suggest selecting and buying the SIN – S 125 rotary cylinder Stt.010.Mssv.BKD002ac.email.ninhd.vT.Bg.Jy.LjvT.Bg.Jy.LjvT.Bg.Jy.LjvT.Bg.Jy.LjvT.Bg.Jy.LjvT.Bg.Jy.LjvT.Bg.Jy.LjvT.Bg.Jy.LjvT.Bg.Jy.Lj.dtt@edu.gmail.com.vn.bkc19134.hmu.edu.vn.Stt.010.Mssv.BKD002ac.email.ninhddtt@edu.gmail.com.vn.bkc19134.hmu.edu.vn an 70 C.vT.Bg.Jy.Lj.Tai lieu Luan vT.Bg.Jy.Lj van Luan an.vT.Bg.Jy.LjvT.Bg.Jy.LjvT.Bg.Jy.LjvT.Bg.Jy.LjvT.Bg.Jy.LjvT.Bg.Jy.LjvT.Bg.Jy.Lj Do an.Tai lieu Luan van Luan an Do an.Tai lieu Luan van Luan an Do an CHAPTER VIII: TESTING WITH INVENTOR PROFESSIONAL SOFTWARE 2015  The spinning wheel section is the largest load in the embryo clamp so it will only last for the rotation of the clutch I SUSTAINABILITY FOR GLASS a) Material and parameters of the material: -

COMMENT From the beginning of the project to the completion of this graduation project, the team has gone through the process of researching, exploring and learning a great deal of knowledge about gear milling with rolling milling technology Learn a lot of structure or from the machine to the CNC rolling milling machine When designing, we always learn more about the method of machining so that when the design is finished, it can be machined More knowledge about using 3D Inventor Profesional 2015 design software, publishing drawings, simulations In the process of work, the biggest difficulty my team encountered was understood the complex structure of the CNC gear hobbing machine while the documents are very limited, most of the design documents are grouped uniformly Look for the catalog of foreign manufacturers and visit the actual machine in Vietnam In addition, because of limited foreign language ability, it is possible to search for material that has ignored important content CONCLUSION Since the first exposure to a large subject and limited knowledge of expertise, the team inevitably missed the shortcomings It should be expected that the teachers in the council contribute ideas from which the team draws experience and have a better view on this research topic Stt.010.Mssv.BKD002ac.email.ninhd.vT.Bg.Jy.LjvT.Bg.Jy.LjvT.Bg.Jy.LjvT.Bg.Jy.LjvT.Bg.Jy.LjvT.Bg.Jy.LjvT.Bg.Jy.LjvT.Bg.Jy.LjvT.Bg.Jy.Lj.dtt@edu.gmail.com.vn.bkc19134.hmu.edu.vn.Stt.010.Mssv.BKD002ac.email.ninhddtt@edu.gmail.com.vn.bkc19134.hmu.edu.vn an 82 C.vT.Bg.Jy.Lj.Tai lieu Luan vT.Bg.Jy.Lj van Luan an.vT.Bg.Jy.LjvT.Bg.Jy.LjvT.Bg.Jy.LjvT.Bg.Jy.LjvT.Bg.Jy.LjvT.Bg.Jy.LjvT.Bg.Jy.Lj Do an.Tai lieu Luan van Luan an Do an.Tai lieu Luan van Luan an Do an REFERENCES [1] Assoc Prof Tran Van Dich -
