Mechanical Technology: Four Stroke Engine
http://e-mech.blogspot.com/2009/02/four-stroke-engine.html
11:04 am / Posted by tech data /. Today, internal combustion engines in cars, trucks, motorcycles, aircraft, construction machinery and many others, most commonly use a four-stroke cycle. The four strokes refer to intake, compression, combustion (power) and exhaust strokes that occur during two crankshaft rotations per working cycle of the Gasoline engine. A four-stroke engine is characterized by four strokes. Or reciprocating movements of a piston in a cylinder:. The cycle begins at top dead center.

8:36 pm / Posted by tech data / comments (0). G-codes are also called preparatory codes, and are any word in a CNC program that begins with the letter 'G'. Generally it is a code telling the machine tool what type of action to perform, such as:. Controlled feed move in a straight line or arc. Series of controlled feed moves that would result in a hole being bored, a workpiece cut (routed) to a specific dimension, or a decorative profile shape added to the edge of a workpiece. Change a pallet. M codes co...

Mechanical Technology: Bending
http://e-mech.blogspot.com/2009/02/bending.html
9:37 pm / Posted by tech data /. Bending is a common metalworking technique to process sheet metal. It is usually done by hand on a box and pan brake, or industrially on a brake press or machine brake. Typical products that are made like this are boxes such as electrical enclosures, rectangular ductwork, and some firearm parts . Subscribe to: Post Comments (Atom). 169; e Tech Tour.

Mechanical Technology: Carnot Cycle
http://e-mech.blogspot.com/2009/02/carnot-cycle.html
10:41 pm / Posted by tech data /. Is a particular thermodynamic cycle, modeled on the hypothetical Carnot heat engine, proposed by Nicolas Léonard Sadi Carnot in 1824 and expanded upon by Benoit Paul Émile Clapeyron. In the 1830s and 40s. The Carnot cycle is the most efficient cycle possible for converting a given amount of thermal energy into work or, conversely, for using a given amount of work for refrigeration purposes. When acting as a heat engine consists of the following steps:. D to A on Figure 1...
