Dynamic Model of Material Deforming Under Microgrinding

Abstract

Model of the process of the dynamic contact interaction of a single abrasive grain with processed material was generated on the basis of the microgrinding process physical parameters analysis. Model is implemented on the basis for the finite elements method, using LS-DYNA software. Following is considered to be condition of destruction - achieving limit deformation of the element with further removing the element.Suggested model is universal in relation to materials under examination, which contact is simulated. If we know strength parameters of the specific processed material and a single grain, we can calculate stresses and deformations in the sample and cutting forces components on a single grain.Performed calculations resulted in obtaining new data on spreading stress and pressure fields in a sample, as well as cutting forces components values on a single grain.
