Research On The Simulation Of Chip Control In NC Turning

With the contemporary mechanic manufacturing converting to automatic, integrated and intelligent advanced manufacture mode. Chip control is crucial in order to realize ideal mechanical manufacture process. This dissertation implements the simulation of chip control in NC turning process through computer simulation technology.Mathematics models for the chip's simulation is established according to the mechanism of it's generation. The regulations of chip's generation curling and breaking is analyzed by studying the different chip-forming theories. A method of chip's geometry feature modeling which is based on Triangle Mesh is presented. Geometry modeling construction and detailed algorithms are discussed. Furthermore, This dissertation analyzes the changing of chip's varieties and sizes under the conditions of cutting parameters' changing, realizes the chips' mesh and solid feature simulation modeling with different cutting parameters.OpenGL as the developing tool is applied. The double buffers of OpenGL make the realization to the graph of chip's simulation more quickly. The chip simulation is embedded into the environment of NC turning simulation in real-time, which realizes the seamless connection between the generation of chip and the removal of material.Region judgment method to verify the intervention among chip workpiece and cutting tool is used. The conditional expression from which the type of chip can be decided is established.With a preferable real-time interactive and transplantable characteristics, this system can be manipulated simply and will have a broader perspective for application.
