Paper Abstract

When a worn or damaged cutting tool is replaced on a numerically-controlled machine tool, the control system must be informed of the coordinates of the cutting edge on the new tool with respect to the tool holder. An automatic setting system is desirable, particularly if tool wear is rapid. In the instrument to be described, a silhouette of the tool tip is imaged onto two linear self-scanned photodiode arrays which effectively form a crosswire fixed with respect to the machine bed. The tool is driven towards the crosswire position and when its image intercepts the arrays the control system stores the coordinates of the tool holder.
