Electric discharge machine and electric discharge machining system

An electric discharge machining system capable of positioning-controlling a machining position, the electric discharge machining system comprising:

• an electric discharge machine including
• a temperature sensor that detects an environmental temperature, a command-value calculation unit that calculates a command value relating to the machining position, a set-value storage unit that stores therein a correction-coefficient set value, a command-value correction unit that estimates a displacement amount of a reference position based on a detected value of the temperature sensor and the correction-coefficient set value stored in the set-value storage unit, and that corrects the command value calculated by the command-value calculation unit using the estimated displacement amount, a measurement unit that measures a transition of the displacement amount of the reference position and a transition of the detected value of the temperature sensor, and that outputs a measurement result, and a setting change unit that receives an input of a correction-coefficient calculated value and that updates the correction-coefficient set value stored in the set-value storage unit to the correction-coefficient calculated value;
• and
• a server that includes a data reception unit receiving an input of the measurement result output from the measurement unit, and that calculates and outputs the correction-coefficient calculated value input to the setting change unit based on the input measurement result, wherein
• the server includes a database unit accumulating and storing therein the input measurement result or the output correction-coefficient calculated value, and determines, when a new measurement result is input to the data reception unit, whether to output a correction-coefficient set value based on the newly input measurement result based on a storage content of the database unit.
