PURPOSE:In a digital indicating device for feed-in amount in the machining, stability indicating function of machining condition is incorporated in line with feed-in amount indication by means of a digital indication for easy readout of vibration width of machining clearance. CONSTITUTION:This device is composed of a device A and B. The device A is composed of the following, i. g., a converting circuit A1 in which feed-in direction of the machining equivalent to the increase and reduction of the feed-in amount, is selected to a pulse a of positive direction and a pulse b of not positive direction and then is output, a counter circuit A2 to calculate the above mentioned pulse and an indicating circuit A3 to effect digital indication receiving the output. On the other hand, the device B is composed of the following, i. g., a converting and driving circuit B1 to light up a luminous diode, D0 - D9, in relation to the decimalized number after a signal c of a cord, B, C, and D corresponding to the minimum figure indicatin number of above indication circuit A3 is converted to a decimal cord. |
