机械加工工艺基础（Basis of machining process） Fundamentals of mechanical processing The first chapter 1. What are the system components of a typical mechanical manufacturing company? What are the meanings? Describe the development of mechanical manufacturing techniques. The second chapter 1. How to define the Angle gamma, alpha o, kappa r and lambda s of tool orthogonal plane reference plane pr, ps, Po and cutter Angle? Im going to graph it. 2. Draw a simplified picture to represent the finished surface, transition surface, the surface of the surface of the car, the size of the back, the nominal width of the cutting layer and the nominal thickness of the cutting layer, respectively. 3. Draw facing tool orthogonal plane frame geometry Angle 45 ° kappa r = predominate, kappa r = 15 ° predominate, gamma o = 10 °, Lambda ˊ s = 6 °, alpha o = alpha o = 6 ° and calculate the gamma p, alpha and gamma f p, alpha f the annotation on the diagram. 4. What is the difference between tool labeling and working Angle coordinate system? What is the requirement for the material of the cutting part? What kinds of tool materials are commonly used nowadays? 6. What are the ultra-hard tool materials? What are the characteristics? In what circumstances? 7. The schematic diagram represents the three deformation zones of the cutting process, indicating the deformation characteristics of the three deformation zones. 8. What are the characteristics of friction between chip and tool? 9. How to measure the cutting deformation? How? What are the factors? 10. How is the dandruff formed? How does it affect the cutting process? What measures should be taken to avoid the occurrence of debris tumors? What are the main factors affecting the temperature of the cutting? How is it affected? 12. What is the effect of the cutting fluid? What kind do you have? Whats the occasion? 13. Reasons for the normal wear of the cutter and the wear of the tool? What is the cause of wear of high speed steel tool and hard alloy
