What is meant by "soft foot" in alignment work?

The term "soft foot" in alignment work refers to a condition where one or more machine feet do not have even contact with the base or foundation. This misalignment can occur due to various reasons, such as uneven surfaces, worn or damaged feet, or improper installation of the machine. When a machine has soft foot, it can cause misalignment during operation, leading to vibrations, uneven wear, and potentially premature failure of components.

Understanding soft foot is critical for millwrights because it can significantly affect the performance and longevity of machines. Ensuring that all feet of the machine make even and solid contact with the base is essential for achieving proper alignment and functionality. Detecting and correcting soft foot is one of the first steps in alignment procedures to prevent further complications during operation.
