Cutting feed sensing device |
摘要 |
A feed rate sensing system for a drilling machine or the like in which a linearly movable cutting tool-supporting block carries a rotatable tool spindle. Linear motion of the supporting block is converted to rotation of a screw and an encoder driven by the screw generates feed pulses representing feeding of the tool toward a workpiece. A proximity switch unit monitors rotation of the tool spindle and produces rotation pulses in relation thereto. A counter and latch circuit produces a digital output representing the feed rate of the tool-supporting block per revolution of the tool spindle and this digital output is converted to a voltage level representing the actual feed rate. A circuit compares such actual feed rate voltage with a desired feed rate voltage, the difference therebetween being applied to a meter.
