A Study on Multi-factor Geometry-Physical Modeling and Simulation in Machine Tool Cutting Processes

Abstract

Geometric-physical modelling and simulation of tool machining processes is a reasonable realization for manufacturing prediction and verification. An effectual simulation system is based on the correct cutting mechanism and accurate geometric calculation. By integrating the scheme of CNC code analysis, process planning and optimization, cutting mechanism model and other related aspects, micro cutting details are expected to be simulated in advance, detected and monitored in the process and analysed afterwards, to achieve the purpose of "Verification IS Production". Based on this vision, this paper proposes a research framework of micro geometric modelling and physical simulation for machine tool cutting. On the basis of continuous improvements in 3D modules for cutting geometry simulation, the physical simulation research and verification is carried out with several typical scenes, in which the mappings between real occasions and simulation system are established. With the cutting physical models, this paper deeply investigated the simulation calculation and correction for various factors affecting the cutting performance and indicators, and finally verifies, analyses and optimizes them through actual machining environments. The purpose of this paper is to explore a feasible way for richer scenes and further research through the multi-element modelling of several comprehensive cutting cases and in-depth micro geometry and physics investigation. Later experiments indicate that the framework performs well and bring good references to similar researches and applications.
