Considering the thermal growth value at the machines is crucial when aligning machines that experience thermal expansion or contraction due to changes in temperature. Machines typically expand when they heat up and contract when they cool down. This thermal growth can significantly affect the alignment between coupled machines, leading to misalignment issues that might cause vibrations, increased wear, or mechanical failures.

Taking the thermal growth value into account allows maintenance personnel to properly adjust the alignment based on the expected operating temperatures. This proactive measure ensures that the machines are aligned appropriately throughout their operating range, minimizing the risks associated with thermal expansion or contraction. By understanding and applying the specific thermal growth characteristics of the materials involved, one can maintain optimal alignment during operation, which is essential for reliable performance and longevity of the equipment.
