scriber
Used to apply a specific torque value to a fastener
torque wrench
Type of torque wrench that show the actual torque on mechanical, dial, or electronic scale
Indicating torque wrench
Type of torque wrench that signals when torque is reached
signaling torque wrench
Concentrate the force from hammer blow to area of tip
punch
Type of punch that has a 60deg angle of tip
center punch
Type of punch that is spring loaded
automatic center punch
Type of punch Used to drive out a bolt/pin
drift punch
Type of punch that has a parallel shank
pin punch
Used for separating material but also for producing grooves and notches
Saw/sawing
Used to remove/reduce material from metal/wood
file
A process of filing that alters the size and shape of a part and considerable amount is removed
rough process
A process of filing that smoothens a surface and doesn’t remove much material
Finish process
A file cut that has a very smooth finish
curved tooth (dreadnought)
A filing technique where file is moved crosswise to the edge side by side until they form a radius
filing a convex (rounding the corners of sheet metal)
A filing technique where file advances sideways
filing a concave
A filing technique that is used for final finish to remove raw edges
draw filing
Used to clean files
steel brush
Used to tighten drill
reamer
Used to secure parts/components when working
clamping
To create an aerodynamically smooth surface
countersinking
Used to cut external threads (male thread)
stock and die
Used to cut internal threads (female thread)
Tape wrench and hand tap set
How to thread using tap set
1.)Taper Tap 2.)Intermediate Tap 3.)Bottoming Tap
Used to remove burrs around the edges
debarring tool
Used to provide HIGH QUALITY and ACCURATE hole
reamer
Used to measure roundness or smoothness
Dial Test Indicator
A type of PME in simple construction that measures dimensions in a faster way
Vernier Caliper
A type of PME that measures dimensions more accurately. It has a main scale and a spindle
micrometer
Used for fine grinding
abrasive wheel
Most common hand held motor for drilling sheet metal using compressed air
pneumatic drill
Used to determine drill bit size
drill gauge
Circumferential speed of drill
drill speed
A drilling machine that is mounted in bench/floor
pillar drill
Used to locate drill holes
hole finder
Used to keep drill bits 90deg to the surface when drilling
drill guide
Used to block the drill to achieve a desired hole depth. It locks into drill with screws
drill stops
Used to accurately drill rivet holes
nut plate drill jig
Highest point of drill (blade)
margin
Helical groove and lowest point of drill
flute
Peripheral portion of body between adjacent flutes
land
A part of drill which includes the flute, margin, and land
Body
Plain and cylindrical part of drill with no teeth
shank
A type of riveting joint where materials overlap each other (single shear)
lap joint
A type of riveting joint where materials are connected by an inner lug (single shear)
butt joint
A type of riveting joint where materials are connected by an inner and outer lug. For this reason
weight and drag increases (double shear)
Should be 2.5-4 times thicker than the thinnest sheet metal
rivet diameter
Should be 1.5 times larger/longer than rivet diameter
rivet length
Size of drill hole in relevance to the rivet shank
drill hole should be 0.1mm larger than rivet shank
The cause of rivet damage where upset head is too small
hole is too large and rivet length is too short
The cause of rivet damage where upset head is too large
rivet length is too long
Cause of upset head to crack
- Too heavily squeezed rivet
- No heat treatment
- False storage of cooled rivets
Cause of rivet shaft to drop during squeeze
- Too long rivet
- Too large hole
- Dolly contaminated
- Dolly is not perpendicular
Distance between rivet center and element’s edge
Edge margin (for boeing)/edge distance (airbus)
Distance between fastener rows
Spacing
Distance between rivets
Pitch
