Tooling_U Chapter 6 Vocab Flashcards
Angled in comparison to the major surfaces of a part. These surfaces are created during chamfering.
Bevel
A metal consisting of iron, over 1.11 percent carbon, and 1 to 3 percent silicon offering heat resistance and compressive strength. This is often used as a machine-based material because it dampens vibrations.
Cast Iron
Machining a small angled feature along a part edge. This helps to remove burrs and aid in part assembly.
Chamfering
Milling that requires non-linear tool movement along two or more axes at the same time to produce a curve surface feature. This helps create complex shapes.
Contour Milling
The unintended movement or repositioning of a cutting tool or component due to a mechanical force. When this happens, a cutting tool can cause poor surface finish and inaccurate dimensions.
Deflecting
A milling operation involves a relatively wide cutter that removes material from the part to produce a flat surface. This is typically done to establish a part’s height on the mill
Face Milling
The process of cutting a channel or a passageway on the inner or outer surface of a cylindrical workpiece. During this, the tool is fed into the rotating workpiece radially to a specified dimension.
Grooving
What is the word used to describe something that rotates from one fixed position to another fixed position?
Indexes, Lathe turret, and mill tool changes index tools into place
A geometrically shaped component made of hardened material is placed into a tool holder to provide a cutting edge. This offers multiple cutting edges and can be indexed to present a new cutting edge after the prior edge is excessively worn.
Insert
A naturally occurring material with high electric and thermal conductivity, luster, density, and strength. Somes example are copper, iron, nickel, and lead.
Metals
A material consisting of very large molecules that are characterized by lightweight, high corrosion resistance, a high strength-to-weight ratio, and a low melting point. Most of this material can be easily shaped or formed.
Plastic
The use of a milling cutter to create an interior recess on the surface of a workpiece. This type of milling can create square, round, or rectangular pockets
Pocket Milling
A machine operation performed on a lathe that feeds a cutting tool along a non-linear path. This creates complex or curved features in a cylindrical workpiece.
Profiling
An unprocessed material that has not yet been manufactured.
Raw Material
A multi-point cutting tool with straight cutting edges that is used to enlarge or smooth holes that have been previously drilled. This can look similar to a drill but lacks a cutting point.
Reamer
A cutting pass that emphasizes high material removal rates at the possible sacrifice of surface finish or accuracy. These cuts are often the first cuts made in a machining process.
Roughing
A milling operation that produces a narrow channel or groove in the workpiece. During this milling process, an end mill engages the workpiece on its bottom and sides
Slot Milling
The use of a shorter, sturdier drill to locate a hole for drilling. This form of drilling often uses a drill size slightly larger than the hole diameter to leave a chamfer after the hole is drilled.
Spot Drilling
Cutting a workpiece to form a shape with a gradually decreasing diameter, similar to the shape of a cone. This is performed on a lathe.
Tapering
The component of the lather that holds that number of cutting tools. This rotates to place tools in the cutting position.
Turret
The unintended movement or repositioning of a cutting tool or component due to a mechanical force. This, or deflection, of a cutting tool can cause poor surface finish and inaccurate dimensions.
