Material Properties - correct answer Ways to describe the behavior of material in response to physical forced Metal properties - correct answer crystalline structures Strong, hard, and ductile High electrical and thermal conductivity Opaque and reflective Cast metal - correct answer initial form is a casting Wrought Metal - correct answer Metal that has ...

single point tool - simple cutting device with a cutting edge on one end or along the edge or a rod/bar/strip Use on lathe for: -Turning (or straight turning) -Facing -Taper turning -Contour turning -Chamfering -Boring -Threading speed - cutting speed denoted by (v). surface speed of the workpiece at tool tip. surface finish - The waviness, roughness, lay, and flaws of a surface. Also referred to as surface texture. machine tool - mechanically operated tool for cutting or shaping wo...

Dislocations - a defect in the crystalline lattice. Dislocations move within a structure when stress is applied Pinning - inhibits the dislocation from moving within the structure resulting in the metal becoming stronger and more brittle. Precipitates - small atoms that fit within the vacant spaces between base metal atoms Entanglements - grains of a structure becoming stretched out. Created by cold working Tensile strength - A measure of how much stress from pulling, or tension, a materia...

Machining: straight turning, facing on a lathe, threading, boring, drilling, center drilling, reaming, tapping, face milling, end milling, broaching - straight turning - using a tool to rotational remove material with straight cuts facing - using a tool to remove material from the face of a workpiece threading - creating threads on a workpiece boring - expanding the inside of a hole using a tool drilling - creating a hole within the workpiece center drilling - done before drilling, making...

Dislocation - a defect in the crystalline lattice, it moves within the structure when stress is applied Pinning - When pinning occurs, the dislocation cannot move. This results in a harder, stronger, and more brittle material. Precipitates, entanglements, and grain boundaries can pin a material Plastic Deformation - When there is a permanent change in shape to the material due to stress Tensile strength - A measure of how much stress from pulling, or tension, a material can withstand before...

Casting - A process in which metals are melted and poured into a die and solidified Expendable molds - Molds made of sand, plaster, ceramics Permanent molds - Molds made of metals with strength at high temperatures Composite molds - Molds made of two or more materials such as sand, graphite, and metal. Could have permanent and expendable portions Sand casting - Casting of material that is permeable, collapsible, strength, reusable, and has thermal stability Flask - Supports the mold Cope...

Ductility - Determines ability to shape sheet metal Shearing - An operation where a blank sheet metal is removed from a large sheet by subjecting it to shear stresses using a punch and a die. Slug - Piece of metal punched out. Can be reused or discarded. Punching - A shearing operation that separates a scrap slug from the work piece when the punch enters the die Punching keeps exterior, blanking keeps interior - Difference between punching and blanking Conventional Blanking - Similar to p...

Turning - Answer- A process in which the major motions of the cutting tool are parallel to the axis of rotation of the rotating work piece. Facing - Answer- A process in which the major motions of the cutting tool are at right angles to the axis of rotation of the rotating work piece. Creates a flat surface or grooves on the end of the rotating work piece. Boring - Answer- A material removal process that enlarges, straightens, and improves the position of a hole in a tubular work piece or ...
