A Non-Dimensional Analysis of Tool Edge Radius Effect on the Mechanics of Micromachining

摘要

The effect of tool edge radius on the mechanics of micromachining, both in terms of plasticity and tribology is significant. Through an experimental study, the responses of normalized process variables namely tool-chip contact length, deformed chip thickness and machining force were evaluated for varying relative tool sharpness. A non-dimensional analysis of the interrelationship among the process variables indicate a transformation in chip formation mechanism under an extreme condition is reported.
