The objective was to develop a reasonably priced machine tool with tool pre-setting and manual data input applying principles of computer language integrated in the machine concept. The base of this new machine is the well-known hand-operated standard NC-turning machine. The electronic control produces contours with the aid of high performance servo drives. It is stressed that microprocessors are a vital part of the electronic control applied. The cost-effectiveness to be achieved with this new solution is shown in a diagram (Figure 8).
