Sine Bar is a precise angle measuring instrument. It is used to measure angles very accurately or to align the workpiece at a given angle. Sine Bar is the most accurate instrument for measuring angles. Sine bar is made up of high carbon high chromium corrosion resistance steel. Sine bar is made with this material…
Single point cutting tool is used in lathe machine, shaper machine and many different machines.It is used for operations like turning, facing, camfering, boring, shaping etc. Single point cutting tool has only one main cutting edge called Principal cutting edge which arises from the intersection of rake surface and principal flank surface.It is named single…
Polytropic Process can be defined as the process in which heat absorbed by the gas due to unit rise in temperature is constant.A polytropic process is a thermodynamic process that can be expressed using the following equation.PVn=C, It is aPolytropic process equation.Where,P is the pressureV is the volumen is the polytropic indexC is a constant The exponential n can have…
Closed Cycle Gas Turbine is an internal combustion engine that operates on rotary motion instead of reciprocating motion.This turbine works on the principle of the Brayton Cycle. Closed Cycle Gas Turbine is an extended version of Open Cycle Gas Turbine. A cooler is added to the Open Cycle Gas Turbine to make it a Closed Cycle Gas Turbine….
Open Cycle Gas Turbine is an internal combustion engine that operates on rotary motion instead of reciprocating motion.This turbine works on the principle of Brayton Cycle. In this gas turbine, the air is taken from the atmosphere which works as working fluid and after completion of cycle it is released to the atmosphere again. These turbine are…
Hydraulic Diameter is the characteristics length that is used to calculate the Reynolds Number (Re) to determine whether a flow is turbulent or laminar. It is used when handling flow in non-circular tubes and channels. Hydraulic diameter converts a cross-section of any geometrical shape into a circular cross-section. Using the Reynold Number (Re), it can be…
In this article we will see the design and working of Velox Boiler which is used steam power plant. First lets see the principle of its working. Principle of Volex Boiler :- Volex Boiler is based on the fact that when the vlocity of gas becomes more than the velocity of sound, the transmission of…
Chip Thickness ratio is defined as the ratio of the thickness of the chip before cutting to the thickness of the chip after cutting. During cutting, the cutting edge of the tool is positioned at a certain distance below the original. This corresponds to the thickness of the chip prior to chip formation, t1, and as…
Watt governor is the simplest form of centrifugal governors. Centrifugal governors are special type of governors with a feedback system that controls the speed of an engine by regulating the flow of fuel or working fluid.Watt governor has two fly balls attached to two arms of negligible masses. Watt governor is used to supply the…
As the name suggests, the Shaper Machine is used to give different shapes to the workpiece.Shaper Machine is commonly used to produce flat surfaces, grooves, slots, etc.In shaper machine, a single point cutting tool is used which reciprocates and rubs the workpiece and removes unwanted metal from the workpiece in the form of chips.
