MDML -- Home

The Machining Dynamics and Mechanics Laboratory (MDML) at Michigan Technological University is an effort directed by Professor William (Bill) Endres to merge the domains of cutting mechanics and machining dynamics to realize an integrated approach to machine-tool, tooling and process analysis. While there are numerous researchers in the United States and abroad who specialize in machining processes, most concentrate their efforts in either cutting mechanics or machining dynamics. The MDML effort is one of only a few in the world with the breadth in expertise required for bringing the realities of real-process cutting mechanics to the machining dynamics problem. Research outcomes are centered around meaningful measures of process performance, including part quality as defined by dimensional accuracy, surface finish, waviness, burring and residual stress, and other limits on productivity, such as chatter/instability. In other words, traditional focuses of force prediction and thermal modeling are viewed as a means to the end, not the end itself. With a focus on process performance, the MDML aims to conduct basic research motivated by realities of practice and a need to understand qualitatively, and predict quantitatively, the performance of machine-tool systems during their development, planning and diagnosis. Additionally, inspired by pressing challenges of industry practice, concepting of new tooling prototypes is an ongoing effort that is enabled by the findings of the group's fundamental research. Much of the MDML’s research is transferred to practicing engineers through industry collaboration and short courses, as well as university instruction, including two university courses Professor Endres has developed in modeling and analysis of machining.
