Abstract: An infeed control system for a grinding machine is disclosed which includes a distance transducer generating trains of electrical pulses in response to wheelhead movement in either direction on the infeed slide, and a first and second up-down counter receiving and counting these electrical pulses generated, the first of these counters counting up in response to pulses generated by grinding infeed movement, the second counting up in response to pulses generated in response to dressing infeed movement. A series of comparator networks compares these counts with preset values set in the series of comparators, and generates sequencing control signals there from at points in the infeed motions of the wheelhead corresponding to the preset values. To compensate for the effect of the changes in wheel diameter due to dressing operations, an arrangement is provided which inhibits the counting up of the counter responding to electrical pulses generated by grinding infeed motion occurring after each dressing operation for a count total equal to the dressing depth.

Abstract: A fixed member and a movable member are provided together with means for providing a cyclic wave pattern upon moving the movable member relative to the fixed member. The direction and precise extent of movement are determined by observing the pattern and the extent is indicated as a digital readout. Comparatively inexpensive components are used to determine and indicate the major portion of the digital readout. Logic means is employed for determining at least one digit, such as the least significant digit, of the readout using electrical signals in a substantially static condition whereby such digit is determined absolutely and independently of any previous movement of the movable member.
