Abstract

To provide a wire electric discharge machine which can appropriately perform thermal displacement correction of upper/lower guides even when the installation environment changes. Provided are a storage unit (21) that stores temperatures of machine elements as temperature data, and a rendering unit (22) that digitizes the installation environment and renders as environmental data. Additionally provided are a position command unit (23) that commands a relative position of the upper/lower guides; and a relational expression calculation unit (24) that sets the temperature data environmental data as input data, sets the relative position as training data, and calculates the relational expression by way of machine learning. Further provided are a relational expression decision unit (29) that calculates a correction amount by substituting the temperature of the machine element into this relational expression, and in the case of error between the relative position of the upper/lower guides based on this correction amount and the relative position commanded by the position command unit (23) being small, decides this relational expression as a formal relational expression; and a correction execution unit (25) that performs correction on the relative position of the upper/lower guides using this relational expression.
