Course module —
Metal cutting principles and Cutting Tool Technology
Semester : 1
Aims
The objective of this course is to introduce advanced topics in metal cutting theory. This approach will be employed to analyze mechanics of cutting, economy in cutting, alternative methods to cutting technology. Also, chip control and machine vibrations will be an within the scope. This course will also provide participants with cutting edge technology know-how and information on how quality cutters with the right tool geometry can be manufactured. Participants will also learn how to use state-of-the-art tool & cutter grinder to verify and generate cutting tools of excellent quality from the advanced grinding software.
Intended learning outcomes
On completion of the unit students will be able to:
Ø Ø have the insight to the mechanics of metal cutting
Ø Ø apply the fundamentals and principles of metal cutting to practical applications
Ø Ø evaluate machined workpiece surface finish and dimensional accuracy’s
Ø Ø determine the lifetime of a cutter through monitoring cutting forces and energy consumptions
Ø Ø have the knowledge to the design of cutting tool
Assessment
The course objectives will be assessed by the following methods:
Ø Assignments - 20 marks
Ø Final exam - 80 marks
