Research status and development trend of simulation prediction system for grinding process

Grinding as the last process of most products machining, directly affects the accuracy and surface quality of the products. Multi-parameters input and output, and nonlinear mapping between the input parameters and output parameters of grinding process are the key factors of computer simulation technology. The theory of computer simulation technology is introduced, based on the current status of research on grinding process and various prediction models, including grinding kinematics model, grinding force model, grinding temperature and grinding fluid model, and the current research status in China and abroad on the simulation prediction systerm for grinding process, which are combined of computer simulation technology and the theory of forcasting models are detailedly analyzed. The paper focuses on elaboration of native researchers＇ achievements on the software development of simulation prediction system for grinding process and finally looks forward to the development trend of simulation prediction system in grinding process.
