Accuracy In Design And Manufactor Flashcards
(24 cards)
What is a high carbon steel scriber
Harder than the metal its marking its a scribe to create measured marks
What is engineered blue
Applied to the surface of the metal to show clear markings in contrast to the blue layer applied a can bee easily taken off.
What is a beam compas
Sometimes called tramels
Larger radi than a divider can create
What is a divider
A compas like contraption hat uses high carbon steel scribes to mark the circle
What is a external and internal adapter
Used for checking dimensions
Whats timber marked with
What a kind of a pencil
Whats a carpenters pencil
A pencil that has a larger lead to avoid breakages
What is used to mark polymer
A pen or sometimes a scribe
What is the metric international system of units
IS
The idea that the international standards of mesurements are the same where everyone uses m
In product design mm is primarily used tho
What is a cross line level
A laser beam machine that marks out complicated fabrications, ceasing perfect horizontal and vertical lines
Whats a surface plate
A precise flat surface used as a reference plane for measuring and inspecting various engeneering and manufacturing processes
Whats a surface plate and gauges fitted with digital or dial reroutes
Used in accuracy mesurements markings of peice required in engeneer applications
Whats a try square
Marks perpendicular lines to an edge
Whats a marking gauge
More a line of continuous distance on a piece of timber
Whats a combination square
A try square in the added feyures to be able to mark out speciific leths by owing along the ruler edge as well as being able to create miter angels (45)
Whats a center punch mark
It is a equipment that makes a small indentation into the metal to allow the drill to center itself and not “wander”
What are CMMs
Co-ordinate measuring machines
Tool used for precices measuring evolving fine tolerances
What are the high precision work machines
Micrometers
Vernier calipers
Co-ordinate measuring machines
Profile projector
Digital test gauge
What is tolerance
The allowance for a part to measure wider or smaller than the base mesurements
What’s a profile projector
a precision measuring instrument used in manufacturing and quality control to magnify and project the silhouette of a small object onto a screen for accurate measurement and inspection
What’s a go/ no go gauge
Where the go and fit in the sample and the no go and does not fit in the sample this means it fits within the tolerance
This equipment measures tolerance simply
What’s a jig
Devices used to control the motion of a tall relative to a workpiece. These can be things such as a drilling jig that is used to ensure the holes are drilled in the correct location every time as well as a mitre jig that is used to create mitre joints.Using a jig takes out the need for marking.
Fixtures
These are robust frames withholding points in clamps that are used to hold a workpiece firmly in place for machining welding another manufacturing operations take place. It’s essential that every component assemblies is held in exactly the same position each time. The manufacturing process is carried out to ensure consistency.
Template
A template is a rigid shape for a pattern that’s often made of manufactured board or a metal sheet that used to transfer a design onto a work piece this is such as transferring shapes or designs onto wood using a pencil .
