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 stick motion correction method which corrects stick motion which occurs at the time of reversal of a feed axis of a numerical control machine tool stores a position command to be commanded to a servo motor from an NC program of a numerical control machine tool for each predetermined control period from a current position command to a position command after a predetermined time, calculates a reversal correction command based on the stored position commands, calculates an advancement time for advancing a timing of addition of the reversal correction command to a speed command or torque command of the servo motor from the reversal timing of the servo motor, based on information obtained from operation of the servo motor and adds the reversal correction command to the speed command or torque command of the servo motor to correct stick motion at a timing advanced from the reversal timing of the servo motor by exactly the advancement time. Due to this, it is possible to provide a stick motion correction method which enables correction of stick motion by a high precision.
