WIRE ELECTRIC DISCHARGE MACHINE HAVING MOVABLE AXIS ABNORMAL LOAD WARNING FUNCTION

摘要

A wire electric discharge machine includes a machine learning device that learns an adjustment of an axis feed command of the wire electric discharge machine. The machine learning device determines an adjustment amount of the axis feed command by using data related to a movement state of an axis, and adjusts the axis feed command based on the determined adjustment amount of the axis feed command. Subsequently, the machine learning device performs machine learning of the adjustment of the axis feed command based on the determined adjustment amount of the axis feed command, the data related to the movement state of the axis, and a reward calculated based on the data related to the movement state of the axis.

主权项

1. A wire electric discharge machine that moves an axis in accordance with an axis feed command by a program or an operation of an operator, comprising:
a machine learning device that performs machine learning of an adjustment target parameter of the axis feed command in the movement of the axis and an adjustment amount of the adjustment target parameter, wherein the machine learning device includes:
a state observation section that acquires state data as information indicative of a movement state of the axis in the movement of the axis;a reward condition setting section that sets a reward condition;a reward calculation section that calculates a reward based on the state data and the reward condition;an axis feed command adjustment learning section that performs the machine learning of an axis feed command adjustment; andan axis feed command output section that determines the adjustment target parameter of the axis feed command and the adjustment amount of the adjustment target parameter as an adjustment action based on a result of the machine learning of the axis feed command adjustment by the axis feed command adjustment learning section and the state data, adjusts the axis feed command based on the determined adjustment action, and outputs the adjusted axis feed command, wherein the axis feed command adjustment learning section performs the machine learning of the axis feed command adjustment based on the adjustment action, the state data acquired by the state observation section after the movement of the axis based on the outputted adjusted axis feed command, and the reward calculated by the reward calculation section.
