What is the basic function of a megger?
A Megger is a device that will test the insulation of the circuit it is connected to. It produces a DC voltage to check for leakage current from the conductor to ground. It then will give you the value of insulation in Mega Ohms. Generally anything less than one Mega Ohm per thousand volts is poor insulation. Be careful when using this device because it does produce high DC voltages and it can give you an awakening jolt. It is most...
What is CNC engineering?
it is a specialisaton in mechanical engineering. CNC refers to computer numerical control. so, using the computer codes (G codes and M codes), a program is written for machining operation. these codes describe the movement of tool while machining. ...
How do you test tensile strength of rope?
The same way that you test the tensile strength of anything - break it in a universal testing machine! You have to be careful how you hold the rope though - you obviously cannot grip it the way you would grip a metal specimen (since the grips will cut the rope). Therefore the rope may be locked into special rope-testing grips or tied around a T-bar or pin in a particuar way. As long as the rope breaks n the central "guage...

What is a lathe cutting tool made from?
Now a days verities of materials are using for making lathe cutting tools. In earlier days Hardened high carbon steels were used. High Speed Steel (HSS) came next to HCS. Ordinary carbide inserts of different grades came after HSS. Coated carbide inserts of various grades suitable for machining different metals and alloys are predominant now. Ceramic and diamond inserts are the latest cutting tool materials using for the machining of materials having very high hardness. ...
What is the difference between hydraulic pump and hydraulic motor?
A hydraulic pump uses an external mechanical force to pressurize the hydraulic fluid. A hydraulic motor uses the pressurized hydraulic fluid to apply a mechanical force an external machine. See the difference between a pump and a motor. ...
What does cnc mill do?
A CNC mill has a table that moves by Computer Numerical Control (CNC), to drill or mill parts that are very accurate and repeatable. On a CNC mill the material is clamped and the tools are rotated into or against the material to cut into it. Apart from the first clause, the second sentence describes milling-machines generally, but a further aspect of CNC machines is that the tools are also changed, and the speeds and feeds set, by the code. The feeds are driven...
