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 (df) is proportionately related to peak current(Ⅰp) and pulse duration (ton).The actual dressing experiment was conducted to demonstrate the simulation model.There is a relationship between fractal dimension (df) and the surface morphology of diamond grinding wheel.
