Class Vocabulary
Term
Definition
accuracy
The exactness of a measurement produced compared to the desired result.
band sawing
The use of a flexible saw blade constructed from a continuous loop or band of metal.
boring
The process of using a single-point tool to enlarge a preexisting hole. Boring is commonly performed on a lathe but is also possible on a mill.
broach
A multi-point cutting tool with a series of progressively changing teeth that can both remove metal and finish the surface of a workpiece in one pass.
broaching
The use of a multi-point cutting tool to shape and finish either the interior of a hole or the surface of a workpiece.
casting
A manufacturing process that pours a liquid material into a hollow mold until the material cools into a solidified shape.
chamfering
Machining an angled edge around the end of a cylindrical workpiece.
circular sawing
The use of a round saw blade with teeth around its perimeter.
contour
A curved surface or part feature that is cut into a workpiece.
counterboring
An operation that enlarges the end of a predrilled hole to allow room for a head of a screw or nut.
countersinking
The cutting of a beveled edge at the end of a hole so that the head of a screw can rest flush with the workpiece surface.
cutting
A machining process that uses a tool to create chips and remove metal from a workpiece.
cutting off
A cutting process, also known as parting, that cuts a finished part from bar stock.
drilling
The process of using a multi-point tool to penetrate the surface of a workpiece and make a round hole.
end milling
A milling process that uses the sides and end of an end mill to cut a variety of shapes.
face milling
A cutting process that uses a mill to cut a flat surface by positioning the tool at a right angle to the workpiece.
facing
An operation performed on a lathe that feeds a cutting tool across the end of a cylindrical workpiece to shorten its length.
fastener
Devices that are used to join and assemble parts together.
flute
The passageways that twist up the length of the drill and allow for the exit of chips and cutting fluids.
form milling
A milling process that uses a mill with a unique shape that is imparted to a workpiece.
grinding
The use of an abrasive wheel to wear away at the surface of a workpiece.
grooving
The process of cutting a narrow channel or passageway into the outside diameter of a cylindrical workpiece.
hacksawing
The use of a long blade mounted in a bow-shaped frame. Cutting takes place using a reciprocating, or back-and-forth, motion.
honing
A process that uses abrasive stones to reshape dimensions from a previous operation. Honing can also be used to achieve a certain surface finish.
inner diameter
The interior surface of a hole in a workpiece.
interrupted cutting
Any machining operation involving a cutting edge that enters and exits a workpiece. Milling operations involve interrupted cutting.
knurling
A forming process that adds a pattern on the exterior of a workpiece, either for cosmetic reasons or better handling.
lapping
An abrasive process that removes the last bit of unwanted material. A lapping process sometimes uses an abrasive paste that is rubbed across the part to gradually smooth it.
machine tool
A power-driven machine that uses a cutting tool to create chips and remove metal from a workpiece.
metalworking
A material manufacturing process that produces parts by mechanically deforming metal into parts. Stamping and forging are two major types of metalworking processes.
mill
A multi-point tool that is used to remove metal from the surface of a workpiece.
milling
The use of a rotating multi-point cutting tool to machine flat surfaces, slots, or internal recesses into a workpiece. Milling includes a wide range of versatile metal cutting operations.
multi-point tool
A machining tool that has two or more cutting edges.
outer diameter
The outer surface of a cylindrical workpiece or feature.
pocket
An interior recess that is cut into the surface of a workpiece.
profiling
An operation performed on a lathe that feeds a cutting tool along a non-linear path to create conical or curved features in a cylindrical workpiece.
reaming
The use of a cutting tool with straight cutting edges to enlarge or smooth holes that have been previously drilled.
reciprocating
Having a repeated back-and-forth movement.
saw
A multi-point cutting tool that is used to rough cut a part to a certain length.
sawing
The use of a multi-point blade to cut through metal and separate it into pieces.
single-point tool
A machining tool that has a single cutting edge.
slab milling
A milling process that uses the slab mill that rotates on an axis parallel to the workpiece. Slab milling produces flat surfaces.
slotting
A milling process that uses a mill to cut a narrow ridge into the surface of a workpiece.
spotdrilling
The use of a shorter, sturdier drill to locate a hole for drilling. Spot drilling often uses a drill size slightly larger than the hole diameter to leave a chamfer after the hole is drilled.
tap
A multi-point tool that is used to cut internal threads into a hole.
taper turning
An operation performed on a lathe that feeds a tool at an angle to the length of the workpiece in order to create a conical shape.
tapping
The process of cutting internal threads in a round hole with a multi-point tool.
threading
The process of cutting a long, spiraling groove into a workpiece with a single-point tool. Threading processes are essential for the creation of fasteners.
t-slotting
A milling process that uses a t-shaped milling cutter to machine a ridge or slot the shape of an inverted T into the surface of a workpiece.
turning
A machining operation that rotates a cylindrical workpiece while a single-point tool is guided along the length of the part. Turning is performed on a lathe.
