Lathe Maintenance Ontology (LMO)
By: Keith Fitzsimmons
IE 500 Final Project – Fall 2014
Scope
Create an ontology which outlines a machines
necessary preventative maintenance based on a
set time period.

Applications
Outlining the required preventative maintenance necessary
to ensure proper operation lifespan of equipment.
Original equipment manufacturers can use information to
see required maintenance on a competitors machine similar
to their own.
Creation of a centralized location for the storage of all
maintenance tasks necessary to complete preventative
maintenance on a specific piece of machinery.

Existing Ontologies
Manufacturing Service Descriptive Language (MSDL)
Focuses on solely manufacturing process.
Industrial Maintenance Management Ontology (IMAMO)
Focuses on what is needed to create a preventative maintenance
program.

MSDL
• General overview
of the
manufacturing
process and its
capability.
• Does not include
maintenance
anywhere in the
process.

Existing Databases
Computerized Maintenance Management Software(CMMS)
These programs manage machine maintenance using chart style
databases.
This style program is normally controlled by a single company,
organization or site where the machinery is used.
Equipment identifiers may not be unique to a machine in this
database if it is used by a large organization.
11
LMO – Continuants
• The continuants
are the machines,
their preventative
maintenance
schedule and
objects needed to
conduct
maintenance
tasks.
12
LMO- Preventative Maintenance
Schedule
• The preventative maintenance schedule is
recommended by the original equipment
manufacturer.
• Adherence to this impact the warranty on the
machine.
13
LMO - Occurents
• These include the
practiced maintenance
regimen; the
maintenance tasks and
time periods which are
used to create the
maintenance regimen.
14
Maintenance Regimen
• Maintenance to be
•
completed as prescribed by
the preventative
maintenance schedule.
15
Important part of this
ontology as different
machines can have the
same Maintenance Task at a
different time period.
