Predictive Maintenance Saves Money
Routinely monitoring equipment using predictive technologies and data collecting can help better plan for equipment repairs and save money in downtime and replacement costs. ALAN GAMBSKY, AARROWCAST INC., SHAWANO, WISCONSIN
T
he traditional views of maintenance in heavily capitalized industries such as metalcasting may trend
more along the lines of cost avoidance. Seen as a necessary chore, mainte- nance is considered a cost center, with too high inventory costs and a low return on investment. Tis belief can affect the culture
and performance of an organiza- tion and indicated silos of knowl- edge, function and power instead of
shared experience, common goals and resource management. Maintenance doesn’t have to be viewed as a cost center. It is a resource that can and should be utilized to maximize safety, environmental responsibility, efficiency, utilization, quality delivery and morale. Maintenance and engineering efforts are reflected in bottom line costs. Routine condition monitoring of
equipment using predictive mainte- nance technologies can detect develop- ing equipment wear early in its failure
mode. Tis allows for planning of the repair before catastrophic failure while extending the remaining life of an asset. Predictive maintenance technologies
have reached a level of maturity and cost now affordable to most depart- ments. Having this capability onsite can show a quick return on investment through the use of condition-based repair intervention, improved mainte- nance planning, improved equipment availability, and support of precision maintenance practices. Repairs that historically were made on a time-based schedule can be deferred if the running condition shows no reason for repair or replacement. Tis can lead to reduced inventory of spare parts while increas- ing the effectiveness of the mainte- nance schedule.

Procedure-based maintenance utilizes a computerized maintenance management system to standardize an operation, improving completion times, quality and repeatability. As the CMMS database grows, it becomes a repository for the cumulative knowl- edge of the operation. Fast ROIs are
