I have a number of 20x20 paver step stones in the backyard. Some of these stones have been pushed up by tree roots. So this weekend I removed about a dozen of these step stones to expose the roots to see if I can do something about it. I found a round concrete disc about 12" in diameter under one of the step stones. I thought it's a round step .

•What is a CNC Machine? •CNC : Computer Numerical Control •Conventionally, an operator decides and adjusts various machines parameters like feed , depth of cut etc depending on type of job , and controls the slide movements by hand. In a CNC Machine functions and slide movements are controlled by motors using computer programs. It discusses that CNC machines use computer programs to control slide movements and machine functions rather than a human operator. The evolution of numerical control is described beginning in 1947 with the development of using punched cards to operate digitron systems. Different types of CNC machines such as mills, lathes, and EDM machines . 3. 1.2 Introduction Milling is a cutting operation with a geometrically specified cutting edge in which the tool makes the rotating main movement, and the feed as well as the infeed movement are generally made by the work part. Milling operations are classified according to the position of the milling axis towards the work part, i.e. between face milling and peripheral milling.
