Abstract: To solve the wheel geometry and position for the integer cutting tool groove machining process,two groove machining strategies that were based on the existed Double-oblique (DOB) wheels and based on the optimized DOB wheel and its position were introduced.An objective function consist of diverse accuracy requirements was built to convert the problem into minimum solution of objective function.A groove prediction model with strong robust was built based on the space analytic geometry theory and graphics algorithm.Therefore,the groove profile or structures such as rake angle,core radius and groove width could be deduced by the wheel geometry and position.The influence of wheel positions on the machined groove geometry was discussed.The Niche Particle Swarm Optimization (NPSO) was employed and modified to solve the objective model.Three cases were carried out to validate the study.
