What is Public and Private IP Addresses?


Difference between Public and Private IP Addresses Private IP Addresses: When many computers or devices connect either to the cable or to the wireless, they create a private network. Within this network, a unique IP address is assigned to share files and resets to each device. The IP address of all the devices in this network is called private address. Public IP addresses: The public IP (image)

What is IP Address?


IP Address definition IP Address means Internet Protocol. This is a Numerical label that is used to identify all the devices (i.e. computers, printers etc) of the network. Any IP address mainly works in two form, one for hosting and network interface identification and second one to identify the location of another device. When the desingers designed the IP address, the IP address was a(image)

Milling Process - Definition and Principle


Definition of Milling Process A milling machine is a machine tool that removes metal as the work is fed against a rotating multipoint cutter.  The milling cutter rotates at high speed and it removes metal at a very fast rate with the help of multiple cutting edges.  One or number of cutters can be mounted simultaneously on the arbour of the milling machine. This is the reason that a milling (image)

Crater Wear | Definition with Diagram


What is crater wear? More common in ductile materials which produce the continuous chip. Crater wear occurs on the rake face. At very high-speed crater wear predominates.   For crater, wear temperature is main culprit and tool defuse into the chip material & tool temperature is maximum at some distance from the tooltip.  Crater depth exhibits (image)
