Abstract prediction of Workpiece profiles and Theoretical model for steady state ECM of axially or etric cavities is developed. The model paid special attention to the hydrodynamic and thermal aspects of the Piracess Theoretical formulae describing electrolyte 2wessure and temperature distributions along the working gap are derived and numerically solved for selected .ix=erimental conditions. Comparison of results with =x7erimental findings proved the potentiality of the -- =cre tical model and its usefulness as a technique tool design. .-.eoretical and experimental pressure distributions indicated the presence of subatmospheric pressure along the working gap. The minimum subatmospheric pressure values are encountored in the frontal gap and found to increase in the down stream direction. Decreasing electrolyte flow velocity, by increasing the tool feed rate, improved the situation in the frontal gap by increasing subatmospheric pressure va lues. An increase in the subatmospheric pressure va lues in the frontal and transition gaps took place Vi th increasing the tool radius of curvature. Despite |
