Speed measurement on automatic abrasive cutting machine

Tiles and special bricks are processed according to their type on automatic abrasive cutting machines. The objective is fast throughput times with the best quality result. Here, the setting parameters for the rotational speed, the circumferential speed of the
cutting disk and the feed rate of the movable table are important. The table movement is acquired by a rugged draw-wire displacement sensor with incremental encoder.
A digital tachometer calculates this speed and displays it.
