摘要： The tolerable maximum feed rate Fd is calculated in real time during operation based on the tolerable minimum moving time Ta to be determined by the data interpretation and the moving distance L of each machining block. If the command feed rate Fc exceeds the tolerable maximum feed rate Fd, the actual feed rate for the block is set to the tolerable maximum feed rate Fd, thereby realizing smooth deceleration and preventing mechanical shock of the machine tool and reduction in machining accuracy. Required time for each processing element is determined in advance, the sum of processing times corresponding each element is calculated by judging the processing mode element contained in machining for each block. Then, the feed rate is controlled by determining the tolerable minimum moving time for each block based on the calculated sum of processing times.

摘要： A wear amount of a working tool T during the machining of a workpiece is estimated during the machining, and a positional command generated in accordance with a predetermined machining program is sequentially corrected during the machining based on the estimated wear amount of the working tool T. The workpiece W is machined in accordance with the corrected positional command. Also, the wear amount of the working tool T upon the interruption of the machining operation is calculated, and the positional command generated in accordance with the predetermined machining program is corrected based on the calculated wear amount of the working tool so that a tool edge position of the working tool T upon the interruption of the machining operation coincides with the tool edge position of the working tool T upon the restart of the machining operation when the machining operation is restarted at a position where the machining operation has been interrupted. The workpiece is machined in accordance with the corrected positional command.
