What is reactive maintenance?
An approach that addresses problems only when they arise, where maintenance is triggered by equipment malfunctions or failures.
An approach that prevents problems with malfunctioning equipment
In design, a strict sequence from concept to delivery without revisiting earlier stages is known as what?
Linear approach
Iterative approach
Spiral development
Concurrent engineering
Which statement defines preventive maintenance (PMP)?
Scheduled maintenance aimed at repairing assets before they fail
Non-critical low-cost repairs after failure
Maintenance only when a breakdown occurs
Decommissioning equipment after end-of-life
According to the R6 of sustainable design, what question might a designer ask for 'Reduce'?
Can the amount of material needed to manufacture the product be reduced?
Can the product be made more expensive to increase perceived value?
Can packaging be made larger to improve shelf presence?
Can the product use more energy to enhance performance?
A significant disadvantage of reactive maintenance concerning asset lifespan is what?
It can lead to shorter life expectancies of assets
It increases warranty coverage automatically
It eliminates the need for spare parts inventory
It reduces safety risks compared to preventive maintenance
Describe "Just in Time" concept in Manufacturing
In manufacturing, what differentiates power tools from hand tools?
Power tools are powered by a battery, electricity, fuel, or compressed air; hand tools require manual labour to use
Power tools require no training while hand tools do
Hand tools are always more precise than power tools
Power tools are used only in prototyping
Explain the difference between quality assurance and quality control
Name the four main scales of production.
One-off production, batch production, mass production, continuous production
Prototype production, serial production, agile production, lean production
Craft production, cellular production, flexible manufacturing, discrete manufacturing
Pilot production, custom production, automated production, manual production
'Prototype' in manufacturing refers to which item?
A draft version of a product that allows exploration of ideas and design concepts before full development
A mass-produced final product
A spare part used for maintenance only
A marketing sample with no functional testing
What is 'continuous production'?
A flow production method used to manufacture, produce, or process materials without interruption, often operating 24/7
A prototyping technique used during design reviews
A seasonal manufacturing approach
A batch-based inspection method
Which statement defines a 'product layout' in a factory?
A layout where equipment or work processes are arranged according to the progressive steps by which the product is made, such as an assembly line
A layout that groups equipment by function only
A layout focusing on raw material storage
A layout organized by team preferences without process logic
What is automation in manufacturing?
Technology by which a process or procedure is accomplished without human assistance
Manual control by skilled operators
A quality assurance technique
A packaging method only
Which tool is designed to apply a specific amount of twisting force (torque) to a fastener?
Torque wrench
Pipe wrench
Combination pliers
Nut driver
Monitoring data relating to machine status and mean time between failures are part of ?
What is Condition-Based Monitoring (CBM)?
What is the name for the L-shaped driver that fits into hexagonal recesses in bolts and screws?
Allen key (hex key)
Phillips screwdriver
Torx driver
Pozidriv screwdriver
Which screwdriver has a cross-shaped tip designed to fit into cruciform screw heads?
Phillips
Flathead
Torx
Robertson (square)
Monitoring machine status and environmental data is part of which maintenance approach?
Operations monitoring
Reactive maintenance
Scheduled replacement
Total productive maintenance
A company mass produces parts for motor vehicles. The manufacture of each part is
split into three main stages:
• Stage 1 - Machining
• Stage 2 - Assembly
• Stage 3 - Finishing
The production manager has noticed that workers at Stage 2 are not always ready
to receive the machined parts from Stage 1 as they are still working on assembly of
previously received parts. This is causing delays at both Stages 2 and 3. As a result
there has been a reduction in both overall company production efficiency and morale
amongst the workers.
Explain, using examples, how introducing a visual management system could help to
address these issues.
