Study of the Sensitivity of Surface Topography on the Dynamic Milling Force near the Joint of Mold

Abstract

Most large covering parts mold use panel board type joining together of hardened steel. The vibration and the milling force is more bigger when milling process the spell near joint. They affect spell near joint processing quality. Analyze of the dynamic milling force, vibration surface morphology change of the sensitivity of the joining together with the cross-correlation function for analyzing the sensitivity of the dynamic milling force of mold spell near joint surface morphology. Experimental study shows that the dynamic milling force and the surface morphology characteristic curve cross-correlation function absolute value can reach 0.952 when the tool path and splice joints into 90°.And the cross-correlation function absolute value of milling force and the surface morphology characteristic is larger than vibration signal one. When the tool path and the joint Angle is small, the milling force influence on the surface morphology is lesser, so process should try to choose the smaller Angle seam.
