Parameter adjustment device and parameter adjustment method

A parameter adjustment device that adjusts a command value generation parameter set that is a plurality of parameters used to generate a tool travel command including a group of interpolation points per unit time on a tool path calculated on a basis of a machining program for machining a workpiece, the parameter adjustment device comprising:

• feature calculation circuitry to calculate a feature of machining by simulating an operation of a machine tool to be controlled on a basis of the tool travel command;
• evaluation index calculation circuitry to calculate one or more evaluation index values for evaluating a machining result on a basis of the feature of machining;
• first optimal solution search circuitry to infer the evaluation index values corresponding to a first search command value generation parameter set by using a first learning result for inferring the evaluation index values from the command value generation parameter set that has been learned by using the command value generation parameter set and the evaluation index values, and to, by using a result of inference, search for command value generation parameter set candidates that are a plurality of command value generation parameter sets that simultaneously optimize the respective evaluation index values;
• and
• display control circuitry to display, on a display, the feature of machining calculated when the command value generation parameter set candidates are set on a command value generation device that generates the tool travel command and the command value generation device operates, and the respective evaluation index values in association with each other.
