in a typical NC system the numerical data which is required for producing a part is maintained on a punched tape and is called the part program, The part porgram is
arranged in the form of blocks of information, Where each block contains the numerical data required data required to produce one segment of the work-piece, The punched tape is moved forward by one block each time the cutting of a segment is completed. The block contains, in coded form, all the information needed for processing a segment of the work-piece.
