摘要： This invention relates to a computer numerical control (CNC) machine tool system having a novel terminal controller and system therefor to control a machine tool generally with at least two axes and more probably three, with stepping motor controls for point-to-point positioning of the machine tool to an almost infinite variety of steps (generally not more than 200). The novelty resides in the ease of programming directly on the terminal controller of the CNC machine tool system. Generally at least some editing and offsets will be programmed from the machine tool.The terminal controller consists of a microprocessor with some RAM and ROM, together with address and data bus plus I/O for magnetic tape handling and display for 6 to 8 digits in each of the X and Y positions, together with numeric keyboard for data input to the program steps and functional keys to control operation-automatic, manual and step-by-step, as well as controls for program input from tape to memory and memory to tape.Particular features include the ease of inputting a program and preparing a tape and then editing the tape while in operation. Further features include circular and linear interpolation. For circular interpolation there are no quadrant limitations and a full or partial circle may be cut.
