In response to the high cost and limited instrumentation available on commercial tribometers a student designed tribometer was conceived, built, and tested. This tribometer combines multiple tribology testing configurations into a single compact and reconfiguration tribometer, dubbed the multifunctional tribometer. This tribometer is also capable of operating in expanded experimental spaces not covered within the limited scope of industry standardized tribological tests. Specifically, this tribometer is able to conduct rotary tests in a reciprocating fashion; this capability is unavailable on any other tribometer published so far in literature or available commercially. Following an overview of the industry standards and the tribometer’s capability is an uncertainty analysis for the reciprocating block on ring testing regime of the multifunctional tribometer. As this test method is totally unique to this machine it is necessary to prove its validity and accuracy. This is done through the use of an uncertainty analysis which is then expanded across all experimental spaces covered by the testing configuration. Additionally, an uncertainty budget has been made which shows what aspects of the machine would be most worthwhile to upgrade to improve performance. Finally, a case study is included which involves an experiment testing the lubrication properties of WD40 in this reciprocating block on ring configuration of the multifunctional tribometer.
