Design & Manufacturing - Short Answer Questions from AMIE Exams

Name two allied welding processes.
Brazing and soldering

Tool signature
Tool signature is the description of the cutting part of the tool. There are two systems for tool signature. (i) Machine reference system (or American Standard Association system) (ASA) (ii) Tool reference system (or Orthogonal rake system) (ORS)

Database Management System (DBMS) 
A database management system (DBMS) is system software for creating and managing databases. The DBMS provides users and programmers with a systematic way to create, retrieve, update and manage data. A DBMS makes it possible for end-users to create, read, update and delete data in a database. The DBMS essentially serves as an interface between the database and end-users or application programs, ensuring that data is consistently organized and remains easily accessible.

Hot and cold working of metals 
The metal working processes are derived into hot working and cold working processes. The division is on the basis of the amount of heating applied to the metal before applying the mechanical force. Those processes working above the recrystallization temperature are hot working processes whereas the below or termed as cold working processes.

Modelling vs. Simulation 
A model is a product (physical or digital) that represents a system of interest. A model is similar to but simpler than the system it represents while approximating most of the same salient features of the real system as close as possible. 
A simulation is a process of using a model to study the behaviour and performance of an actual or theoretical system. The purpose of a simulation is to study the characteristics of a real-life or fictional system by manipulating variables that cannot be controlled in a real system.  Simulating is the act of using a model for a simulation.

Hard Information and Soft information
  • Hard Information: is quantitative in nature and generally consists of facts, statistics, and other formally published Information. See also: Document, Fact.  Hard Information Examples: Maps, Compass, Library, Dictionary and Encyclopaedia 
  • Soft Information: is essentially qualitative in nature and consists of ideas, suggestions, opinions, Rumour, gossip, feedback, anecdotes, speculation, and tips. Soft Information Examples: Friends, News and the Internet.

Robot
A robot is a mechanical or virtual artificial agent, usually an electromechanical machine that is guided by a computer program or electronic circuitry, and thus a type of an embedded system.

Feasibility
As the name implies, a feasibility study is an analysis of the viability of an idea. The  feasibility study focuses on helping answer the essential question of “should we proceed with the  proposed project idea?” All activities of the study are directed toward helping answer this question.

AS/RS
An automated storage and retrieval system (ASRS or AS/RS) consists of a variety of computer-controlled systems for automatically placing and retrieving loads from defined storage locations.

Group technology
Group technology or GT is a manufacturing technique in which parts having similarities in geometry, manufacturing process and/or functions are manufactured in one location using a small number of machines or processes. GT is based on a general principle that many problems are similar and by grouping similar problems, a single solution can be found to a set of problems, thus saving time and effort.
