摘要： A device for detecting grinding wheel life is provided including a truing tool wear detection device for detecting a total wear amount of a truing tool after every truing operation and an arithmetic and judgement circuit arrangement. The circuit arrangement compensates for the total wear amount by a theoretic in-feed amount through which the truing tool has to have been in-fed from its original position when the grinding wheel is worn down to a predetermined limit. Further, the circuit arrangement calculates an actual in-feed amount of the truing tool and by comparing the actual in-feed amount with the compensated theoretical in-feed amount, judges whether or not the grinding wheel has been worn down to a predetermined limit.

摘要： A feed safety apparatus for a movable member slidably supported on a stationary bed of a machine tool. A feed device moves the movable member at various speeds. A hydraulic cylinder is fixedly mounted on the movable member and includes a piston slidably received therein. A reference plate member is secured to the bed and operatively connected to the piston for permitting bodily movement of the hydraulic cylinder and the piston within a predetermined distance, but restraining movement of the piston beyond the predetermined distance to cause relative movement between the hydraulic cylinder and the piston. A fluid flow regulating device is disposed between the pair of cylinder chambers of the hydraulic cylinder for restrictively controlling relative movement between the hydraulic cylinder and the piston.

摘要： A feed control apparatus wherein a servomotor control device responsive to feed pulses distributed from a numerical controller controls a d.c. servomotor to advance a grinding wheel carriage of a grinding machine through the rotation of a feed screw successsively at a speed-up feed rate, a rapid feed rate, a slow-down feed rate and a grinding feed rate. A detection device is provided, which outputs a velocity checking signal to an abnormality confirmation device when the carriage reaches a velocity checking point defined within a slow-down feed range. When confirming that the feed rate of the carriage has exceeded a reference feed rate lower than the rapid feed rate, the abnormality confirmation device applies a stop signal to an emergency stop control circuit in response to the velocity checking signal, so that the rotation of the servomotor is immediately discontinued.

摘要： A method of grinding a workpiece for shaping it into a cam by imparting a rotary motion and a rocking motion, which conforms to the profile of a master cam, to the workpiece. In the first rough grinding step, a grinding wheel is rapidly entered into the workpiece while the workpiece is rotated at a low velocity. In the second rough grinding step, the grinding wheel is rapidly entered into the workpiece while the workpiece is rotated at a velocity greater than the low velocity. In the third rough grinding step, the wheel is rapidly entered into the workpiece while the workpiece is rotated at a high velocity. Each of the three steps includes a step for removing the portion left uncut in such a state that the infeed of the wheel is ceased. The depths of cut in the three steps DS.sub.1, DS.sub.2 and DS.sub.3, respectively, are so set that the following relation holds:DS.sub.1 >DS.sub.2 >DS.sub.3
