Abstract
A numerical controller having a digital computer with a memory device, a feed control device responsive to feed control data supplied from the computer for controlling the servomechanisms of a grinding machine, a data write-in device manually operable for inputting various data and instructions, and a plurality of pilot lamps controllable by the computer. 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.
