Answer: Ideal voltage source is defined as the energy source which gives constant voltage across its terminals irrespective of the current drawn through its terminals.
An amplifier is a device that increase the voltage, current or power of an input signal with the aid of transistor by furnishing the additional power from a separate dc source.
A threaded fastener is a discrete piece of hardware that has internal or external screw threads. They are usually used for the assembly of multiple parts and facilitate disassembly.
The contour of a part - also known as a profile - is normally programmed for milling applications by establishing the depth in the Z axis first, then moving the cutting tool individually along the X axis, Y axis, or both axes simultaneously. For turning applications, either the X axis or the Z axis, or both axes can be used to face, turn or bore a contour. For both types of machining, each contour element contour requires one block of nutting motion.
