Application of fractal theory in electro-discharge dressing diamond grinding wheel

摘要

Electrical discharge dressing and truing of diamond grinding wheel is a non-contact and non-traditional truing and dressing technology. In orde to help selecting optimized parameters under certain conditions such as peak current, etc. Fractal theory is application to set a electrical dischrge model. In this model, the fractal dimension (d_f) is proportionately related to peak current (I_p) and pulse duration (t_(on)). The actual dressing experiment was conducted to demonstrate the simulation model. There is a relationship between fractal dimension (d_f) and the surface morphology of diamond grinding wheel.
