Electro Discharge Machining (EDM) is an electro-thermal non-traditional machining process, where electrical energy is used to generate electrical spark and material removal mainly occurs due to thermal energy of the spark. EDM is mainly used to machine difficult-to-machine materials and high strength temperature resistant alloys.

Thermal problems are also to be considered in traditional machine design. In design of engines, pumps, hydraulic cylinders, excessive temperature and thermal stress are to be prevented to ensure the machine performance. And for processing machines where mechanical precision is important, the effect of thermal expansion need to be considered .

Thermal Transfer Overprinting is a printing process that applies a code to a flexible film or label by using a thermal printhead and a thermal ribbon. TTO uses a thermal printhead and thermal transfer ribbon. The printhead comprises a ceramic coating, covering a row of thermal …

Revisiting the Basics of Laser Cutting - This article talks about the basics of laser cutting machines and provides details on types of laser cutting machines and things to consider when working with them. ... The PowerPoint PPT presentation: "Thermal Cutting" is the property of its rightful owner.

Heat is a measure of how much thermal energy is transmitted from one body to another. We cannot say a body "has" a certain amount of heat any more than we can say a body "has" a certain amount of work. While both work and heat can be measured in terms of joules, they are not measures of energy but rather of energy transfer.

THERMAL AND HYDRAULIC MACHINES UNIT 4 • Consider a vane symmetrical about the x-axis as shown in Figure 2.0. A jet of fluid flowing at the rate of (m dot) kg/s along the x-axis with the velocity u 0 m/s strikes the vane and is deflected by it through angle …

Jan 22, 2013· Thermal & mechanical cutting 1. Thermal & Mechanical Cutting Group Discussion 2. CUTTING OF METALS• Cutting of metals implies severing or removal of metal. Cutting is the process of separating metals, i.e., a metal piece is separated or split into two parts. Cutting of metals is an everyday practice in industry.•

The Machine is a Structural Loop • The structural loop contains all the joints and structural elements that position the tool wrt the workpiece – A stick figure of machine motions can outline the structural loop • The structural loop gives an indication of machine stiffness andaccuracy – Long-open loops have less stiffness and less accuracy

"Temperature is a measure of the tendency of an object to spontaneously give up energy to its surroundings. When two objects are in thermal contact, the one that tends to spontaneously lose energy is at the higher temperature." (Schroeder, Daniel V. An Introduction to Thermal Physics, 1st Edition (Ch, 1). Addison-Wesley.) units
