CAD model and CNC machined part. Computer-aided manufacturing (CAM) also known as computer-aided modeling or computer-aided machining [1] [2] [3] is the use of software to control machine tools in the manufacturing of work pieces.
The cam can be seen as a device that converts rotational motion to reciprocating (or sometimes oscillating) motion. [clarification needed] [3] A common example is the camshaft of an automobile, which takes the rotary motion of the engine and converts it into the reciprocating motion necessary to operate the intake and exhaust valves of the cylinders.
[1] Other 1980s major players in CAD/CAM included General Electric [4] and Parametric Technology Corporation; [5] the latter subsequently acquired Computervision, which had been acquired by Prime Computer. [5] CAD/CAM originated in the 1960s; [6] an IBM 360/44 was used to build via CNC [7] [8] the wings of an airplane. CAD (Computer-aided ...
Calmodulin (CaM) (an abbreviation for calcium-modulated protein) is a multifunctional intermediate calcium-binding messenger protein expressed in all eukaryotic cells. [1] It is an intracellular target of the secondary messenger Ca 2+ , and the binding of Ca 2+ is required for the activation of calmodulin.
NX, formerly known as "Unigraphics", is an advanced high-end CAD/CAM/CAE, which has been owned since 2007 by Siemens Digital Industries Software. [1] [2] In 2000, Unigraphics purchased SDRC I-DEAS and began an effort to integrate aspects of both software packages into a single product which became Unigraphics NX or NX.
SOHC design (for a 1973 Triumph Dolomite Sprint) . The oldest configuration of overhead camshaft engine is the single overhead camshaft (SOHC) design. [1] A SOHC engine has one camshaft per bank of cylinders, therefore a straight engine has a total of one camshaft and a V engine or flat engine has a total of two camshafts (one for each cylinder bank).
A cam engine is a reciprocating engine where instead of the conventional crankshaft, the pistons deliver their force to a cam that is then caused to rotate. The output work of the engine is driven by this cam. [1] A variation of the cam engine, the swashplate engine (also the closely related wobble-plate engine), was briefly popular. [2]
They are heteromeric complexes that comprise pore-forming alpha-subunits and the Ca 2+-binding protein calmodulin (CaM). [1] CaM binds to the SK channel through the CaMBD, which is located in an intracellular region of the alpha-subunit immediately carboxy-terminal to the pore. Channel opening is triggered when Ca 2+ binds the EF hands in the N ...
