摘要： PURPOSE:To process with high accuracy by binarize a detecting output of a non-contacting sensor by a comparator, inputting a counting value of a counter which can obtain a timing of the change of said binary signal as a trigger signal, whereby the center position of a groove in a widthwise direction is operated. CONSTITUTION:A rotary encoder 4 directly connected to a rotating shaft 5 of a work 1 outputs a pulse output to a counter 6. A noncontacting sensor 7 which detects the presence or absence of a groove 2 in the work 1 generates an output to a comparator 8. The comparator 8 binarizes the output of the sensor 7 by a predetermined threshold voltage, outputting the timing of the change of the binary signal as a trigger signal to a buffer 9. An output of the counter 6 is fed to the buffer 9. The buffer 9 reads the integral counting value and outputs the same to an operating processor 10. The processor 10 operates the average of the input counting values, based on which can absolute position of the center of the groove 2 in a widthwise direction is output as an angular information theta.

摘要： PURPOSE:To make it possible to set the coordinate values of the fixed position by simple manipulation, by effectively utilizing the displayed values of the present position of a table in an angular grinding machine. CONSTITUTION:The coordinate values of the fixed position S of an end surface fixing device 35, which is attached to a head 20, with respect to an original point Q of a machine are set. The table 21 supports the center of a master work Wm having an outer diameter (d) at a circular cylinder surface. The amount of movement of the table 21 with respect to an original point Q is detected, and a size (d) is inputted into a numerical control device 40. Then the table 21 is moved. A present position Z1 of the table under the state the end surface of the work Wm is positioned at S is stored in a memory 41. The table 21 and a grindstone stand 27 are positioned so that the end surface and the cylinder surface of the work Wm are contacted with the end surface and the cylinder surface of the grindstone. A present position Z2 of the table under this contact state is read. Based on the size (d) and the value z1, an expression, z1-z2-d/2tantheta is operated, and the result is stored in the parameter area of the device 40.

摘要： PURPOSE:To detect the use limit of the grinding wheel irrespective of the abrasion of a correcting jig by a method wherein the position of the grinding wheel at the time of generation of a speed change signal from a measuring device is detected to ascertain whether or not the detected position of the grinding wheel is remote from the original position thereof. CONSTITUTION:The measuring device 20 is provided on a table 12 of the grinder 10. When a work W is finished to a predetermind size, a speed change singal is generated from the measuring device 20 and a position detector LS detects whether or not a grindstone table 23 has returned to its original position. Further, a digital control device 40 generates pulses to drive circuits 41 and 42 for driving pulse motors 24 and 32 to thereby control the processing of the work W and the correction of the grindstone. When a grind command signal is applied on the digital control device 40 and the forward quick feed of the grinding wheel 22 is started, a signal is generated from a one shot circuit 55 and the moving amount l of the grinding wheel from its original position is detected by a counter 51. Then, the detected moving amount l of the grinding wheel is compared with a reference moving amount lr computed by an operator 50 and a critical detecting signal is generated from the comparator 52.
