This dissertation addresses sustainable manufacturing challenges by exploring new approaches to optimize resource utilization during machining. The focus is on understanding fundamental tribological aspects, particularly during chip formation, with an emphasis on interrupted machining using minimum quantity lubrication (MQL). Investigations into difficult-to-cut materials, such as austenitic stainless steel and Inconel 718, reveal significant reductions in chip-tool contact during initial period of chip formation (IPCF). Thermal modeling establishes correlations between a finite cutting distance of IPCF and a transition temperatures contributing to a better understanding of the process. Practical case studies employing peck drilling and vibration-assisted drilling demonstrate both the potentials and challenges associated with introducing interruptions in continuous machining operations.
