    摘要： A process planning apparatus extracts a region to be machined based on the difference of the shape data before and after machining of the workpiece, replaces the extracted region into combinations of the predetermined machining features, allocates a predetermined fixed cycle to each of the replaced machining features, and applies an assessment function relating to a machining time and a life of the end mill to each of the combinations of the machining features to which the fixed cycles are respectively allocated, thereby selecting a group of the fixed cycles which makes an assessment value obtained by the assessment function optimum as the optimal process. By these steps, it becomes possible to design the process for causing the NC machine employing end mills as a cutting tool to perform a predetermined machining of a workpiece without relying on the experience of the designer, and without necessitating complicated work.

    摘要： A control method for an NC machine tool is provided which ensures a high precision of the contouring control, and allows for extension of the drill life, and reduction in machining time. The control method comprises: generating an operation command signal on the basis of the machining program and a time constant; generating a velocity command signal by multiplying a deviation of a present position signal fed back from the feed drive system (106) from the generated operation command signal by a position loop gain; generating an electric current command signal by multiplying a deviation of a present velocity signal fed back from the feed drive system (106) from the generated velocity command signal by a velocity loop gain; and controlling a drive motor of the feed drive system (106) on the basis of the generated electric current command signal for driving thereof, wherein a machining mode is determined from the machining program and, if the machining mode is a drilling mode, at least one of the operation command signal, the velocity command signal and the electric current command signal is modified when the feed drive system (106) is driven to be retracted opposite to a drilling feed direction.

    摘要： A numerical control apparatus (1 or 20) comprising pecking operation controlling means (12) which make a feed drive system (14) retracted when a cutting load detected by cutting load detecting means (7) exceeds a reference value during a drilling process, the cutting load detecting means (7) comprise a bite load detecting section (8) to detect the cutting load at a biting stage wherein a tool bites a work piece, and a stationary load detecting section (10) to detect the cutting load after the biting stage. The numerical control apparatus (1 or 20) comprises pecking judgement means (11) to judge that the feed drive system (14) should be retracted when a fluctuation load exceeds a specified reference value wherein the fluctuation load is obtained by reducing the bite load from the detected stationary load. When it is judged that the feed drive system (14) should be retracted, the pecking operation controlling means (12) make the feed drive system (14) retracted.
