GATE - MECHANICAL ENGINEERING
QUESTIONS AND VERIFIED
ANSWERS|100% CORRECT|GRADE A+
Computer Aided Manufacturing - ANSWER CAM is defined as the use of computer system to plan,
manage and control the operations of a manufacturing plant through either direct or indirect computer
interface with the plants production resources.
Numerical Control System - ANSWER Numerical control is a method of controlling the movement of
machine component by directly inserting coded instructions, in the form of numbers and letters, into the
system.
Robotics - ANSWER Robotics means a science which enables to design and manufacture robot.
Computer Integrated Manufacturing - ANSWER A computer system that not only helps to design
products but also controls the machinery needed to produce the finished product.
Computer Aided Process Planning - ANSWER Computer Aided Process Planning (CAPP) is a means to
automatically develop the process plan from the geometrical image of the component.
Crystal structure - ANSWER Crystal structure describes the regularity and type of atomic arrangement
within a crystal.
Atomic Packing Factor - ANSWER Atomic Packing Factor (APF) is defined as fraction of volume applied by
spherical atoms as compared to the total available volume of the structure.
Law of conservation of mass - ANSWER Mass can neither by created nor destroyed by any physical or
chemical means.
Stacking faults - ANSWER When grain boundaries on both the sides are parallel to each other with slight
disturbance of bonds in a very region, such grain boundaries are called stacking faults.
