depth, deep, down: Defines the depth of a feature. ⌀ [2] diameter: Diameter of a circle. In a feature control frame , the ⌀ symbol tells you that the tolerance zone for the geometric tolerance is cylindrical. Abbreviations for "diameter" include ⌀, DIA, and D. D: diameter; delta: Abbreviations for "diameter" include ⌀, DIA, and D.
In machining, a counterbore (symbol: ⌴) is a cylindrical flat-bottomed hole that enlarges another coaxial hole, or the tool used to create that feature. A counterbore hole is typically used when a fastener, such as a socket head cap screw or fillister head screw, is required to sit flush with or below the level of a workpiece's surface.
TD – total depth (depth of the end of the well; also a verb, to reach the final depth, used as an acronym in this case [citation needed]) TDD – total depth (driller) TDC - Top Dead Center; TDC – total drilling cost; TDL – total depth (logger) TDM – touch-down monitoring; TDP – touch-down point; TDS – top drive system; TDS ...
Z-44's total measured depth is 12,376 metres (40,604 ft). However, ERD wells are more shallow than the Kola Borehole, owing to a large horizontal displacement. In July 2023, China began drilling deep boreholes, one at the Sichuan Basin expected to reach 10,520 metres (34,510 ft) into the ground and the other at the Tarim Basin with a planned ...
Hole types in engineering: blind (left), through (middle), interrupted (right). In engineering, machining, and tooling, a hole may be a blind hole or a through hole (also called a thru-hole or clearance hole). A blind hole is a hole that is reamed, drilled, or milled to a specified depth without breaking through to the other side of the ...

In manufacturing, a countersink (symbol: ⌵) is a conical hole cut into a manufactured object, or the cutter used to cut such a hole. A common use is to allow the head of a countersunk bolt , screw or rivet , when placed in the hole, to sit flush with or below the surface of the surrounding material (by comparison, a counterbore makes a flat ...
Objects of this type are often represented as a contour map that gives the height (i.e., thickness or depth) of the object at each point. [1] A 2.5D image is a simplified three-dimensional ((x, y, z) Cartesian coordinates system ) surface representation that contains at most one depth (z) value for every point in the (x, y) plane.
