Abstract
To provide a reference temperature setting device, a reference temperature setting method, and a reference temperature setting program capable of setting an appropriate reference temperature for thermal displacement compensation. A reference temperature setting device comprises: an acquisition unit that acquires measured values from multiple temperature sensors installed on a machine; and a determination unit that determines setting timing for a reference temperature for thermal displacement compensation to coincide with a point in time when the measured values satisfy a predetermined condition.
Claims11
A reference temperature setting device comprising:
- an acquisition unit that acquires measured values from multiple temperature sensors installed on a machine;
- and
- a determination unit that determines setting timing for a reference temperature for thermal displacement compensation to coincide with a point in time when the determination unit determines that the measured values from the multiple temperature sensors satisfy a predetermined condition, the setting timing being a point in time at which the reference temperature is set,
- wherein the determination unit determines that the measured values from the multiple temperature sensors satisfy the predetermined condition based on a comparison between a threshold and a difference, the difference being calculated by the determination unit based on a comparison using the measured values.
A reference temperature setting method comprising the following steps to be performed by a computer:
- an acquisition step of acquiring measured values from multiple temperature sensors installed on a machine;
- a calculation step of calculating a difference based on a comparison using the measured values;
- and
- a determination step of determining setting timing for a reference temperature for thermal displacement compensation to coincide with a point in time when determining that the measured values from the multiple temperature sensors satisfy a predetermined condition, the setting timing being a point in time at which the reference temperature is set,
- wherein the measured values from the multiple temperature sensors are determined to satisfy the predetermined condition based on a comparison between a threshold and the difference calculated in said calculation step.
A non-transitory computer-readable medium storing a reference temperature setting program for causing a computer to perform:
- an acquisition step of acquiring measured values from multiple temperature sensors installed on a machine;
- a calculation step of calculating a difference based on a comparison using the measured values;
- and
- a determination step of determining setting timing for a reference temperature for thermal displacement compensation to coincide with a point in time when determining that the measured values from the multiple temperature sensors satisfy a predetermined condition, the setting timing being a point in time at which the reference temperature is set,
- wherein the measured values from the multiple temperature sensors are determined to satisfy the predetermined condition based on a comparison between a threshold and the difference calculated in said calculation step.
