Study on prediction models of milling force for T10 hardened steel

摘要

To represent the relation between force and cutting parameters in milling T10 hardened steel, single factor milling experiments with different cutting parameters were done. The experimental result showed that there exited maximum inflection point in force curve under different speeds, and the relation between force and cutting parameters could not be represented with an uniform mathmatical equation. Respective prediction modal of milling force in low speed and high speed were set up using least-square method, which was significant at level of β=0.0005, and its result of R- test was higher than 0.98. This study indicates that the applicable prediction modals in milling T10 steel with low and high speed are different, predict modals being set up can be used to estimate milling force.
