Abstract
Provided are a fluctuation amount estimation device () capable of evaluating reliability of an estimated value and a correction amount calculation device () including the fluctuation amount estimation device (). The correction amount calculation device () includes the fluctuation amount calculation device (), a correction amount calculation unit (), and a correction amount output unit (). The fluctuation amount estimation device () includes a parameter storage () storing parameters as constituent elements of a neural network obtained by machine learning, an estimation unit () estimating a fluctuation amount relevant to a position of an element arranged in a machine tool () or a fluctuation amount of a distance between elements arranged in the machine tool () for each physical condition information of the machine tool () by means of the neural network with a parameter freely selected from the parameters being omitted, and a reliability evaluation unit () evaluating reliability of estimated multiple fluctuation amounts based on the estimated fluctuation amounts. The correction amount calculation unit () calculates a correction amount for the estimated fluctuation amounts based on the fluctuation amounts, and the correction amount output unit () outputs the calculated correction amount to outside.
