Research of simulation system for cylindrical grinding of centerless-type base on OpenGL

As an accurate and efficient machining technique,centerless grinding occupies an important position in the field of mechanical manufacturing.By taking an infeed centerless grinding as research object,each function module in the simulation system was introduced in detail,and the technical points in the process of the system development have been explored as well.Meanwhile the document reading and reproducing of 3DS model in the simulation system was analyzed,thus the simulation for the centerless cylindrical grinding process was realized by adopting OpenGL.Afterwards a method for calculating height of supporting board was brought forward according to theoretical optimized value of workpiece center height.At the same time,the roundness and the grinding force of the workpiece in time domain was simulated,which result will provide a useful reference for further researching dynamic characteristics of centerless grinding,and improving the machining precision.
