Credits 3

Pre-requisites - None

Core/Elective - Core Course

To give students an understanding of the basics of mechanics of machining and different machining processes so that they would be able to analyze and select appropriate processes/ machines for manufacturing a specific product.

At the end of this course, students should be able to:

1. Describe the chip formation process with possible variations and illustrate the temperature distributions during the metal cutting action.

2. Measure and analyze cutting forces during metal cutting.

3. Describe different operations that can be performed on the lathe, milling and grinding machines and select appropriate operations/machines after technical/economic analysis to machine a given product.

4. Describe types of tool wear and tool failure and calculate optimum cutting speeds for turning, milling, and grinding operations. Perform basic machining operations on lathe, milling, and drilling machines including gear manufacturing, and realize machining to desired tolerance boundaries.

5. Describe the main components of NC architecture and write a simple part programme for a basic CNC machining operation
