Cutting Force Analysis In Micro Milling Of Steel

A Mechanistic Model of Cutting Forces in Micro-End-Milling .

A Mechanistic Model of Cutting Forces in Micro-End-Milling .

The proposed model also uses instantaneous cutting force coefficients that are independent of the end-milling cutting conditions. These cutting force coefficients, determined from measured cutting forces, reflect the influence of the majority of cutting mechanisms involved in micro-end-milling including the minimum chip-thickness effect.
