EXAMPLE 3:  MILLING ALONG X & Y AXIS

Milling Along X and Y-axes: A work piece of 100mm x 50mm has to be machined on all edges with a cutter of 20 mm diameter. Since the work thickness is 15mm, a cutter of 20mm width is chosen. First the tool and work piece are set on the milling machine. Let the set position A of the tool be (0,0,0). The work piece is set on the machine bed and its top surface is 25mm above the bed.  Before actual machining starts, the table travels in X and Y direction till the cutter reaches the corner (nearest) of work piece. It is rapidly moved down up to 2mm above the work piece. Then it moves with a feed up to z= -52mm. Then table feed is given in X direction till the cutter reaches another corner. Similar process is repeated till entire perimeter of the work piece is milled
