摘要： A position command value is compensated by predicting a thermal displacement amount of each part of a machine tool and adding a thermal displacement compensation amount which cancels the predicted thermal displacement amount to the position command value of a feed axis. This thermal displacement compensation amount is adjusted from the error amount between this compensated position command value and an actual machining point. Upon adjustment of this thermal displacement compensation amount, it is possible to determine whether to increase or decrease the thermal displacement amount based on a direction in which an operator moves a tool image or a workpiece image on a screen.

摘要： When machining a workpiece by a machine tool by cutting, a cutting fluid is sprayed to a workpiece machining region. Above a surface of the cutting fluid in a cutting fluid tank, an odor sensor for detecting the odor emitted by the cutting fluid is disposed in the space defined the surface of the cutting fluid in the cutting fluid tank and a cover. Based on the odor detected by the odor sensor, deterioration of the cutting fluid is determined.

摘要： A controller for controlling a machine includes a coolant monitoring function. The controller generates and records history information in which the measurement values of a state of a coolant are associated with time information on the time when the measurement values are measured. Then, a rate of change in a measurement value for a state of the coolant is calculated based on the recorded history information, and a state of the coolant and a countermeasure therefore are determined based on the calculated rate of change in the measurement value.
