Metal Cutting and Machine Tools

By Prof. Asimava Roy Choudhury | IIT Kharagpur

Learners enrolled: 3590

This course would encompass a comprehensive study of metal cutting and machine tools. Within a limited time of 10 hours, this course would elaborate on the theory of metal cutting supplemented with numerical problems. Tool geometry, chip formation, cutting force calculations and measurement, tool wear and other aspects will be given due attention. This would be followed by a descriptive study of the machine tools like lathe, milling, grinding, drilling and shaping machines, followed by numerical problems.

A study would also be made on fixed automation, Computer numerical control (CNC) machines, gear cutting machines, non-traditional machine tools, Rapid prototyping, together with numerical problem solving.

There would be discussions on MCQ at the end of each week of lectures.
