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 tolerable feed rate is calculated to cause mechanical shock not exceeding a tolerable level in an arcuate machining based on the radius of the path of tool movement at arcuate machining portions and the predetermined tolerable acceleration. A deceleration start timing is set by reference to the end of an arcuate machining and the predetermined deceleration so that the feed rate is lower enough to maintain the tolerable mechanical shock at the end of an arcuate machining. An optimum feed rate is set for arcuate and completely circular machining based on the classification judgment of the arc or complete circle.
