Chip Breaking And It's Simulating Research

With contemporary machinery manufacturing converting to automatic, integrated and integrated and intelligent advanced manufacture mode, chip control is crucial in order to realize ideal mechanical manufacture process. This thesis implements the simulation of chip control in turning process through computer simulation technology.Mathematics models for 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 of chip-forming theories. A method of chip's geometry feature modeling which is based on quadrangle developing is presented. Furthermore this dissertation analyzes the changing of chip's varieties and sizes under the conditions of cutting parameter's changing, realizes the chip and the solid feature simulation modeling with different cutting parameters. Under condition of Visual C++6.0 programme, 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 in turning process simulation in real-time, which realizes the seamless connection between the generation of chip and the removal of material.Get the needing parameter through twice calculating of mathematics models. Changing parameters to the same reference frame through reference transforming. Check-up the collided between chip, piece and tool in turning process of through coordinate track of the part of chip generation, and analyzed the coordinate of them in the same coordinate.With a preferable real-time, interactive and transplantable characteristics, this system can be manipulated simply and will have a broader perspective for application.The results of this research that provided the foundation for shortening production cycle of numerical tool and chip breaking forecasting of tool in...
