There are described methods and system for managing machine tool maintenance. The method comprises assessing health data for the machine tool over health assessment cycles, the health data indicative of a performance of the machine tool; triggering first level maintenance events on the machine tool when the health data falls outside of a tolerance; modulating a time interval between the health assessment cycles as a function of an occurrence of first level maintenance events, wherein the time interval is reduced after first level maintenance events and increased after a given number of consecutive health assessment cycles without first level maintenance events; and triggering second level maintenance events on the machine tool when second level maintenance event conditions are met.
