10. Upon what does the cutting capacity of a machine depend? 



11. Define the following expressions: " cutting feed of a tool," 

 "depth of cut," "cutting speed." 



12. Is it possible to cut all metals at the same rate of speed? 

 Explain. 



13. Why is it necessary to have different speeds on a machine 

 tool? How are different speeds obtained? 



14. What is a lathe? Explain the difference in action and uses 

 of different lathes. 



15. What is meant by the expression "size of a lathe"? Why 

 is it important? 



16. What is a simple lathe? Compound lathe? 



17. What is a lathe tool? 



18. Describe a machinist's vise. 



19. What is a screw machine? Explain its action. 



20. What is a drilling machine? Explain its action. 



21. What is a shaper? What is a planer? How do they differ 

 in use and action? 



22. What is a key-way machine? 



23. Explain the purpose of a milling machine. Describe its 

 action. 



24. What is a grinding tool? 



25. Describe the different kinds of power hammers. 



26. Explain the use and action of a vernier. 



27. What is a screw pitch gauge? Thickness gauge? 



28. What is the difference between a general machinist tool- 

 maker and die-sinker? Name some of the principles of science 

 that a general machinist should know in order to understand and 

 do his work intelligently.
