Positioning system for linear motion in programmed machine tools - has incremental position indicator whose visual counter has logic connection to input key

摘要

The positioning system is partic, intended for carrying out reproducible programs in clip cutting machine tools. It consists of a combination of known incremental position indicators, coupled between the stationary and moving parts of the machine tool and comprising a measuring element, precision measuring rod and a visual counter. To the indicator is connected a programmable machine tool control, as in 2628219. to the visual, actual value counter is connected an input key in logic circuit to the rated value store. The input key serves partic. for taking over manually run-up rated values.
