Title:
LIFETIME PREDICTION DEVICE AND MACHINE TOOL
Document Type and Number:
WIPO Patent Application WO/2022/065326
Kind Code:
A1
Abstract:
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.
