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 numerical control device for controlling rotation of a servomotor in response to numerical control data to move a movable member by a commanded feed amount at a commanded feed rate. A velocity detector detects an actual feed rate of the movable member. A register stores an allowable feed rate data. A comparator compares an allowable feed rate data from the register and an actual feed rate from the velocity detector to output an abnormal signal when the actual feed rate exceeds the allowable feed rate. The allowable feed rate data is set into the register each time the commanded feed rate is changed.

The write-in device is operable to input grinding mode designation data, responsive to which the computer serves to illuminate one by one those of the lamps which request the operator to input control parameters necessary for the grinding control in the designated grinding mode. The write-in device is further operable to input the control parameters designated by the illuminated lamps for storage in the memory device. The memory device has stored therein a number of operational sequence programs prescribing the manners in which the grinding machine is to be operated in respective grinding modes. The computer, when receiving an automatic grinding instruction, serves to read out from the memory device the control parameters and one of the operational sequence programs necessary for the grinding control in a designated one of the grinding modes and then, to supply to the feed control device the feed control data after calculating the same from the read-out control parameters and the read-out one of the operational sequence programs.

摘要： A tool position offsetting system for a spare tool, including a tool life detecting device provided for detecting a broken or substantially worn tool and for replacing the same by a spare tool, and a detecting device which detects whether the spare tool is inserted in the tool spindle. If the detecting device makes a detection, an input controlling circuit applies several signals to a numerical controller so as to instruct the same to introduce the dimensional data for the spare tool into the memory of the numerical controller, resulting in amending the offset data stored in the memory before a machining operation. After the machining operation, the input controlling circuit applies several signals so as to remove the dimensional data from the memory, resulting in restoring the tool offset data to its original setting.
