摘要： A processing machine (10) is provided which can accurately evaluate the results of periodic inspection. This processing machine, for processing a workpiece (W), is provided with: an information storage unit (80) which, as reference information (97A), stores information that includes multiple pieces of in-process information (85A-85H), which indicate the processing state when the workpiece was subjected to inspection processing, and processing result information (87A-87C), which has been obtained by measuring the product obtained by the inspection processing; an acquisition unit (60) which acquires comparison information (97B), which includes the processing result information and the multiple pieces of in-process information in inspection processing that was carried out after the inspection processing for which the reference information was acquired; a comparison unit (62) which compares the comparison information and the reference information; and a display control unit (66) which displays on a display unit (68) the results of comparison by the comparison unit.

摘要： Provided is a lifetime prediction device and a machine tool that enable simple prediction of the lifetime of a filter while suppressing a prediction error with respect to a true value. A lifetime prediction device (88) according to one embodiment is provided with: a pressure acquisition unit (90) that acquires in time series a pressure value of a liquid applied to a filter (52); a time acquisition unit (92) that acquires processing time of a designated process; a calculation unit (94) that calculates the amount of pressure change during the processing time; and a prediction unit (96) that predicts a lifetime period before an upper limit value of the pressure of the liquid applied to the filter (52) is reached, by using the pressure value, the processing time, and the pressure change amount at the time of completion of the designated process.

摘要： A wire electrical discharge machine (10) controls a second motor unit (56) including motors for feeding a wire electrode (12) in a wire running direction in which the wire electrode (12) extends, so as to feed the wire electrode (12) at a set feed rate during a machining period from a first time point (T1) at which the wire electrode (12) moving relative to a workpiece (W) in a direction intersecting the wire running direction is estimated to enter the workpiece (W), to a second time point (T2) at which the wire electrode (12) is estimated to exit the workpiece (W). The second motor unit (56) is controlled so as to feed the wire electrode (12) at a feed rate lower than the set feed rate during at least one of a first non-machining period (r1) from a processing start time point (T0) to the first time point (T1) and a second non-machining period (r2) from the second time point (T2) to a processing end time point (T3).
