The amount of material that is injected or poured into a mold. The shot volume includes the volume of all part cavities, as well as the feed system which delivers the material. The amount of material forming the parts relative to the total shot volume is the material yield. The shot volume must be ...
An operation in which a face mill machines a flat surface of the workpiece in order to provide a smooth finish. The depth of the face, typically very small, may be machined in a single pass or may be reached by machining at a smaller axial depth of cut and making multiple passes. For a rough ...
A turning operation in which a single-point tool moves axially, along the side of the workpiece, removing material to form different features, including steps, tapers, chamfers, and contours. These features are typically machined at a small radial depth of cut and multiple passes are made until the ...
Also called the permittivity and denoted DK, or Er. The ratio of the capacitance of an insulator to the capacitance of a vacuum or dry air (the dielectric constant of a vacuum is 1.00000, dry air is 1.00054). Capacitors release charge when a circuit is broken. Capacitance is the ratio of charge ...
The number of parts completed in a single operation when the operation acts on multiple parts at once or one part representing many. For example, a painting operation that paints 10 parts at once will complete 10 parts per operation. An inspection operation that weighs a single part out of every 10 ...
The thickest wall or feature of a part. In molding processes, the maximum wall thickness is used to determine the cooling time because that section will require the most time to cool. In some parts, the thickest section can be easily identified (Trigger), but often several sections should be ...
The depth of the tool along its axis in the workpiece as it makes a cut. In turning, a facing operation has an axial depth of cut relative to the workpiece axis. A large axial depth of cut will require a low feed rate, or else it will result in a high load on the tool and reduce the tool life. ...
In additive fabrication processes, a part is built by adding layers of material upon one another. The build speed refers to how fast the part can be fabricated in this way and depends upon the specific process and equipment being used. Build speed can be measured as the amount of area in one layer ...
