An additional mold device, such as a side-core, that is actuated through one of the four sides of the mold. One or more side-actions can act through any of the four sides of the mold. The number of sides with such a device, referred to as side-action directions, limits the number of possible ...
In some turning operations, the single-point tool used for finishing has a rounded front corner or "nose". The radius of the tool nose, along with the cutting feed, will determine the surface roughness formed by the finishing operation. For a given cutting feed, a larger nose radius will provide a ...
When machining a feature that is open on one or more sides, the tool may be allowed to move beyond the edge of the workpiece. This over-run distance (D) is measured from the edge of the workpiece to the center of the tool. Therefore, an over-run distance of zero will still allow the full feature to ...
The time required for an automatic tool changer to position a new tool. In a milling machine, this includes the time to stop and orient the spindle, remove the current tool, insert the new tool, and start the spindle again. In a turning machine, this time describes the turret rotating to a new tool ...
Chemical symbol Mg, Atomic number 12, atomic weight 24.312. A silvery, moderately hard, strong, and light metal. Used in ductile iron production, steel desulfurization, and chemical reduction. Growing use as substitute for aluminum and zinc in die castings, due to light weight, high strength and ...
A measure of the severity of a deep drawing operation, calculated as the ratio of the blank diameter to the punch diameter. The limiting drawing ratio (LDR) is a measure of a material's deep drawability and is calculated from the largest blank that can be completely deep drawn for a given punch ...
A device that may be used in turning machines to catch a part after it is separated from the workpiece by a cut-off operation. The part catch time ( a component of the idle time) refers to any additional time required in the use of this device, such as moving in or out of position and catching the ...
The highest recommended temperature that a polymer can withstand under no load and without a degradation of its properties. The Deflection Temperature measures the maximum temperature a polymer can withstand under load. The Maximum Service Temperature is also called the Maximum Operating ...
