Thermal Compensation of Sudden Working Space Condition Changes in Swiss-Type Lathe Machining

Abstract The Swiss-type lathe is a specialized turning machine of Swiss-origin with wide range applications across the precision machining industry. Its unique features enable it to mass produce parts at high speeds and precision. However, complex non-symmetric structure tool makes particularly susceptible adverse effects thermal influences. These internal external influences cause an offset center point degrade accuracy produced part. It common practice in for operator open door during production run exchange tools or inspect Consequently, boundary conditions change rapidly when cooler ambient air enters working space heats up after restarted. exhibits short cool-down warm-up cycles which errors abruptly can be challenging compensate, as well known This work develops novel methodology based on artificial intelligence that compensates associated sudden condition changes. results show error residual peaks opening are significantly attenuated peak-to-peak reduced.
