3. Aparna S: LATHE MACHINE MACHINE TOOLS LAB MECHANICAL ENGINEERING
B.Tech. III year students
JNTUH-GRIET

4. Out-of-class Activity
Learning Objective(s) of Out-of-Class Activity
At the end of watching the videos student should be able to
Identify the parts of lathe machine
Know the function of different parts (Understand Level)
Different machine tools
Key Concept(s) to be covered
Parts of lathe machine
Functions of different parts

5. Out-of-class Activity
Lathe parts: (6:46 min)
(2:16 min)
Machine tools: (4:28 min)
Total duration 15 minutes

6. Out-of-class Activity
Aligning Assessment with Learning Objective
Learning Objective
Assessment Strategy
Time
Parts of lathe machine
Arrange the position( which part rests on which part) of parts (cross slide, compound rest, tool, tool post, carriage, saddle) on lathe.
5 min
Functions of different parts
How many guideways are there on lathe bed and what is their function( guide which parts).
3 min
Various operations on lathe
Can drilling operation be performed on lathe? If yes, how it differs from drilling on drilling machine.
10 min

7. Out-of-class Activity
The duration for watching videos is 15 min and for doing assessment questions is 20 min. The total time for out-of-class activity is 35 min. It is equal to almost one class.

8. In-class Activity Learning Objective(s) of In-Class Activity
At the end of the class, students will be able to
identify differences between various machine tools
understand functions of lathe parts

9. In-class Activity
Think-Pair-Share: In our machine tools lab turning operation is performed at 450 rpm and thread cutting operation at 71 rpm. Think: can turning and thread cutting operations can be performed at other rpm s (other than 450 and 71) ( 4min) Pair: discuss answer with your batches and If yes, what changes you notice while performing those operations at other speeds. (6 min)

10. In-class-Activity
Share: share your answers with your class and verify your answers whether the changes you found are same and correct or not. (10 min)

11. In-class-Activity
Above activity is an active learning strategy as in pair phase students discuss about the changes like surface finish in turning and if as the rpm is changed whether feed is to be changed or not. And in turning with change in rpm why the angle and pitch changes. Students think and discuss actively with their peers.
