Rationale
Large numbers of industrial parts have features like teeth, threads, slots, splines, surfaces etc. Quality of these parts depends on parameters aspects such as accuracy of profile, dimension & surface finish controls. These parameters are specified on the product drawing and require suitable machines & cutting tools for its manufacturing. Nano-parts largely used in control systems require specialised manufacturing approach due to their miniature size. Correct selection of process & its parameters on such machines; plays a vital role in obtaining required quality product at optimum cost. This course will make students familiar with fundamentals of such conventional & advance processes on various machines like grinding machines, super-finishing machines, broaching machines, jig boring machines, non-conventional machining processes, Micro Electro Mechanical Systems (MEMS) etc.
Course Outcome
The theory should be taught and practical should be carried out in such a manner that students are able to acquire at least following learning outcomes in cognitive, psychomotor and affective domain on the content specified in this subject.

i. Explain working of grinding, super finishing, gear cutting, broaching, threading, non-conventional and advance machining methods with kinematics and coolant/ lubrication systems stating functions of each element.
ii. Interpret designation system / method of cutting tools and tool holders used on machine tools.
iii. Set the machine and mount the job, cutting tools and tool holders correctly.
iv. Select appropriate cutting tools, work holding devices and cutting parameters for the given work piece.
v. Outline the process and produce the job/product as per given drawing/ specification.
