Optimizing Availability through Reliability and Maintainability
Training Length - 3 Days
7FM Tooling and Equipment FMEA focuses on optimal tooling, dies, molds, and equipment. Components are consumed by time, energy, unexpected material, unexpected interference, and material nonconformities that can damage tooling and equipment. The first focus of improvement is to optimize design parameters for reliability. The second focus is to reduce the time to repair for perishable and high damage risk components as well as tool/die change-over time. Predictive maintenance ensure that the next mission can be satisfied. When predictive maintenance signals a potential failure, components are at the end of their life and must be changed. These expensive components have a reason to be changed. Preventive maintenance is used for basic cleaning, replacing of fluids, inexpensive perishable components, and maintaining adjustments.
