Abstract

This project propose the design of shimless footing system to overcome the misalignment arise from the soft foot. An analysis of the effectiveness of the shimless unit will be compared to conventional shim in rectifying misalignment problem. The soft foot happened when there is a gap between a machine foot and the foundation. The machine frame will actually distort from its resting position as the hold- down bolts are tighten to secure the machine in place. Soft foot also creates stress lines in the frame as a short foot is pinned to the foundation by the hold-down bolt. A classic example of the soft foot is; bar table with one short leg; which occurs when the machine naturally rests on three legs and the fourth leg is short. If it does properly corrected before beginning the actual alignment, it is difficult or impossible to achieve acceptable results. A shimless footing system will be design in order to overcome the soft foot problem. Solidwork were used in the designing stage. By using SolidWork, a shimless system can be easily developed to make sure that it will able to overcome the soft foot problem. The system should be able to provide a new foundation that does not relies on shims in alignment machinery. Then, after a system has been designed, an analysis is done to study the effect on soft foot during the alignment process. It will observe whether the system is effective by comparing to the conventional shim. The design should make the alignment process easier and overcome the soft foot problem arise. There are two basic methods to identified soft foot, which are frame distortion index and the laser soft foot locator. It is predicted that the soft foot problem can be eliminated as the misalignment will not happen again.
