This will help to develop fundamental concepts in metal cutting theory .

This will help to design cutting tool

This will help to design tools for metal forming and sheet metal cutting

This will help to design jig and fixture

Knowledge will be gained in the subject matter

Able to apply theory to practical problems

Knowledge will be enhanced to implement the concept for product development

Knowledge gained will help for higher study in the subject area

This will help to analyse multipoint cutting tools like drilling and milling
