Free Bachelor of Science in Industrial Engineering Manufacturing Process Automation Questions and Answers — Questions and Answers

Question 1: MRP and MRP-II differ primarily in the following ways:

capacity planning
finance (Correct answer)
bom
inventory

Correct answer: finance

Material Requirements Planning (MRP) focuses primarily on planning and managing raw materials and components for production. Manufacturing Resource Planning (MRP-II) expands significantly on MRP by integrating all aspects of manufacturing operations, including production, scheduling, capacity planning, and crucially, financial planning. The addition of financial modules and broader business integration is the key differentiator, making MRP-II a comprehensive enterprise planning system.

Question 2: CRP translates MRP's material needs into

standard hours of load
standard hours of machine
standard hours of man power
all of the mentioned (Correct answer)

Correct answer: all of the mentioned

CRP (Capacity Requirements Planning) is a crucial step in manufacturing planning that translates the material requirements from MRP into the actual capacity needed to produce them. This involves calculating the standard hours of load on machines, the standard hours of manpower required, and the overall standard hours of load on the work centers. Therefore, CRP considers all these aspects to ensure that the necessary resources are available to meet the production schedule.

Question 3: Planning for capacity is concerned with

how much labour required
how many machines required
none of the mentioned
all of the mentioned (Correct answer)

Correct answer: all of the mentioned

Capacity planning is fundamentally concerned with ensuring that an organization has the necessary resources to meet future production demands. This involves determining not only how much labor (manpower) will be required but also how many machines and other equipment will be needed to achieve the desired output levels. Therefore, effective capacity planning considers all these factors to optimize resource utilization and production efficiency.

Question 4: The MRP-II system is said to as a closed loop system since it takes

man power
inventory
finance (Correct answer)
none of the mentioned

Correct answer: finance

The MRP-II (Manufacturing Resource Planning) system is considered a closed-loop system because it integrates various business functions, including finance, with the core manufacturing planning. This integration allows for feedback mechanisms where financial data, such as costs and budgets, are considered when making and adjusting production plans. By incorporating financial considerations, MRP-II ensures that manufacturing decisions are not only feasible from a production standpoint but also financially viable and aligned with business objectives.

Question 5: The best kind of robot for pick-and-place tasks is the one shown below.

jointed arm type
cylindrical
rectangular (Correct answer)
spherical

Correct answer: rectangular

Rectangular robots, also known as Cartesian or gantry robots, are characterized by their ability to move along three perpendicular axes (X, Y, Z). This configuration provides high precision, rigidity, and a large, accessible workspace for linear movements. These attributes make them particularly well-suited for simple, repetitive pick-and-place tasks where objects need to be moved accurately between defined points within a rectangular work envelope.

Question 6: An expert computer program is one that has knowledge in a specific field.

operations symbolizer
expert system processor (Correct answer)
intelligent planner
automatic processor

Correct answer: expert system processor

An expert computer program that possesses knowledge in a specific domain and can use that knowledge to solve problems or provide advice, much like a human expert, is precisely defined as an expert system. These systems are a branch of artificial intelligence designed to mimic the decision-making capabilities of a human expert within a narrow field. They typically consist of a knowledge base and an inference engine to process information and derive conclusions.

Question 7: An expert system's knowledge base consists of both information and

analysis
algorithms
heuristics (Correct answer)
theories

Correct answer: heuristics

An expert system's knowledge base is designed to store the specialized information and problem-solving techniques of a human expert. Beyond factual data and domain-specific information, it crucially includes heuristics. Heuristics are rules of thumb, educated guesses, or experience-based strategies that human experts use to solve problems efficiently, especially when a definitive algorithm is not available or too complex.

Question 8: The arm of a robot is also known as its

end effector
actuator
servomechanism
manipulator (Correct answer)

Correct answer: manipulator

The arm of a robot, which is the primary mechanical structure responsible for movement and positioning, is technically known as the manipulator. It consists of a series of links connected by joints, allowing the robot to reach and interact with its environment. The manipulator's purpose is to guide and orient the end effector (gripper or tool) to perform specific tasks.

Question 9: What kind of actuator produces a lot of power yet is frequently messy?

pneumatic
electric
hydraulic (Correct answer)
none of the mentioned

Correct answer: hydraulic

Hydraulic actuators are known for their ability to generate very high forces and power, making them suitable for heavy-duty applications where significant strength is required. However, a common drawback of hydraulic systems is their reliance on pressurized fluids, which can lead to leaks and spills, making them frequently messy in operation and requiring more maintenance compared to electric or pneumatic systems.

Question 10: A robot is said to be adaptive if it can change its course in reaction to environmental factors.

open loop
non servo
mobile
intelligent (Correct answer)

Correct answer: intelligent

An intelligent robot is defined by its ability to perceive its environment, process information, and make decisions or adjust its actions accordingly. When a robot can change its course or behavior in real-time in response to dynamic environmental factors, it demonstrates a level of intelligence and adaptability. This capability goes beyond simple pre-programmed movements, allowing the robot to handle variations and unforeseen circumstances effectively.

Question 11: Robot programming is the practice of physically moving a robot along the path you want it to take.

robot vision control
pick and place control
continuous path control (Correct answer)
contact sensing control

Correct answer: continuous path control

Continuous path control is a robot programming method where the robot's manipulator is guided through the desired trajectory, and the system records a large number of points along that path. This allows the robot to reproduce smooth, continuous movements, which is often achieved by physically moving the robot's arm or using a teach pendant to trace the intended path. This method is crucial for tasks requiring precise contouring or smooth transitions, unlike simpler point-to-point movements.

Question 12: It is known as "reasoning from a goal state to an initial state."

heuristic
breadth first
bidirectional
backward chaining (Correct answer)

Correct answer: backward chaining

Backward chaining is a reasoning strategy commonly used in artificial intelligence, particularly in expert systems. It operates by starting with a specific goal or hypothesis and then working backward to find the necessary conditions or facts that must be true to support that goal. This "goal-driven" approach contrasts with forward chaining, which starts with known facts and works forward to derive conclusions.

Question 13: Which gadget is most frequently connected to automation?

NC machine
computer graphics workstation
robots (Correct answer)
flexible manufacturing

Correct answer: robots

Robots are perhaps the most iconic and widely recognized devices associated with automation. They are programmable machines designed to perform tasks automatically, often replacing human labor in repetitive, dangerous, or precise operations across various industries. While NC machines and flexible manufacturing systems are also forms of automation, robots represent a highly versatile and direct application of automated technology to physical tasks.

Question 14: Pick the fundamental component for an automated machine tool.

workstation
software
NC tape programming (Correct answer)
logic

Correct answer: NC tape programming

For an automated machine tool, particularly those based on Numerical Control (NC) or Computer Numerical Control (CNC), the fundamental component for its operation is the NC tape programming (or its modern equivalent, G-code files). This programming contains the precise instructions for the machine's movements, tool selections, and operational parameters, dictating how the automated machine will perform its task. Without this programmed sequence, the machine cannot operate automatically.

Question 15: Pick the appropriate robot part from the list below.

software
arm (Correct answer)
coaxial cable
micro computer

Correct answer: arm

The arm is a fundamental and defining physical component of most industrial robots. It is the mechanical structure, consisting of links and joints, that provides the robot with its reach and range of motion. The arm allows the robot to position its end effector (gripper or tool) to perform various tasks within its workspace.

Question 16: A robot's configuration is

spherical (Correct answer)
square
oblong
octagonal

Correct answer: spherical

A common robot configuration is the spherical (or polar) type, which is characterized by a combination of rotational and prismatic joints. This arrangement allows the robot's workspace to approximate a sphere, enabling it to reach objects within a spherical volume around its base. This configuration is distinct from rectangular (Cartesian), cylindrical, or articulated (jointed arm) types.
