CI 9257 PRECISION ENGINEERING L T P C
3 0 0 3 AIM:
The aim is to understand the principles and applications of Precision Engineering.
OBJECTIVES:
The student is motivated learn about the concept of part accuracy, Machining
accuracy and to discuss on the types of errors, and their sources. The student will be
able to understand the need for precision and application. In addition, the student will
enhance his/her knowledge in Precision Engineering and its applications.
UNIT I PRECISION ENGINEERING 8
Introduction – Accuracy and Precision– Need for high precision – concept of
accuracy – tolerance an fits: system – Hole and shaft system – expects accuracy of
a Manufacturing process – types of fits – Selective assembly.
UNIT II MATERIALS FOR PRECISION ENGINEERING 8
Diamond – types-single crystal- PCD – Natural-synthetic CBN - Ceramics – coated
metals and non-metals–High– performance polymer – alloys – refractory metals:
cutting tools – performance – components of instruments – Jewels – self Lubrication
– smart materials – properties – testing – applications.
UNIT III PRECISION MACHINING 10
Precision grinding: IC chip manufacturing- ELID process – aspherical surface
generation Grinding wheel- Designer and selection of grinding wheel-High-speed
grinding-High-speed milling-Micro machining – Diamond turning-MEMS – micro
finishing process – surface roughness measures – concept and non-concept method
– comparison of features with machining process.
UNIT IV ERRORS: CAUSES AND REMEDICS 10
Static stiffness - influence on machining accuracy. Introduction – over all stiffness in
a machine/instrument – errors due to variation of cutting forces – clamping forces –
errors due to compliance while machining. Inaccuracy due to thermal effects: Heat
sources –war dissipation – Geometry of thermal deformation-influence of forced
isstratics dimensional wear of elements – instruments; Machining tools their
influence an accuracy- error due to clamping and setting location.
