<p>PURPOSE:To position a new tool immediately and to attain the next cutting by arrangig tools to a blade stand surrounding a work piece, storing the position of the tip and operating the distance up to the perphery of the work so as to move the tool. CONSTITUTION:The distance from the center of the tip of each tool is set when a blade stand 2 is placed to each axis reference point at a lathe is set and the correction due to wear of each tool is set and the diameter of the workpiece 1 is set. In programming the lathe processing, a T code (selection of tool) is used and the tool number of the tool in use is designated. Then the processing program is used to cut the work and when the required tool is selected and designated by the T code, a CPU in the NC machine reads the tip and work diameter to the tool from a memory. Then the sitance between the tip of the tool and the periphery of the work 1 is operated, the blade stance 2 is moved, the tip of the selected tol is contacted with the periphery of the work 1 to position the tool.</p> |
