Abstract
In a centerless grinding, a roundness error of ground workpiece depends on various parameters such as center height angle γ, blade angle φ, rotational speed of workpiece nw and stock removal rate Z′. This paper investigates the influence of these parameters through a computer simulation method to optimize grinding conditions for a minimum roundness error. Centerless infeed grinding tests were conducted and the results were compared to those of the simulation. Conclusions are as follows: (1) The new computer simulation method, which is combined with the geometrical and grinding conditions, is proposed, and the results agreed with actual grinding results. (2) Roundness can be improved by adjusting nw. (3) Optimum grinding conditions can be expressed by a pair of parameters (γ, κ). As the results of simulation and grinding tests, the values of (γ, κ) were about (6°, 0.45).
