An end milling operation can produce a variety of features, including profiles, slots, and pockets. A profile is a peripheral cut along an external or internal edge of the workpiece with a length equal to the complete perimeter, just one side, or even a part of a side. A slot is a slot cut in the ...
Also called elastic modulus and coefficient of elasticity. A measure of the rigidity of metal. The ratio of stress, below the proportional limit, to corresponding strain. Specifically, the modulus obtained in tension or compression is Young's modulus, stretch modulus or modulus of extensibility; ...
An operation in which a boring tool enters the workpiece axially and cuts along an internal surface to form different features. The boring tool is a single-point cutting tool, which can be set to cut the desired diameter by using an adjustable boring head. Boring is commonly performed after ...
ASTM E10. A common standard method of measuring the hardness of metallic materials. A hardened steel or tungsten carbide ball is pressed into the smooth surface of the material with a specific load. A microscope in used to measure the diameter of the indentation in the material surface and then ...
The depth of the tool along its radius in the workpiece as it makes a cut. If the radial depth of cut is less than the tool radius, the tool is only partially engaged and is making a peripheral cut. If the radial depth of cut is equal to the tool diameter, the cutting tool is fully engaged and is ...
The amount of longitudinal stress a material can sustain when in tension, measured in units of force per unit area. Tensile strength is commonly expressed as megapascals (MPa) or pounds per square inch (psi) of original cross section. The amount of stress that a material can withstand before it ...
