Grinding efficiency and profile accuracy of diamond grinding wheels dressed with wire electrical discharge conditioning (WEDC)

Abstract Super abrasive diamond grinding wheels are the most promising tools for precision machining of advanced ceramics and carbide materials. However, efficiency conventional conditioning these is limited owing to high dressing tool wear, long process time, low form flexibility, induced damage grains. Wire electrical discharge (WEDM) an alternative method superabrasive with electrically conductive bonding In this study, cylindrical plunge alumina ceramic a resin-bonded wheel investigated. The assigned type resin bond contains copper particles accordingly wire (WEDC). Conventional (mechanical) WEDC methods used generating same profile on two similar wheels. As result, specific energy was reduced up 26% 29% during rough finish grinding, respectively. Reduced forces, along more effective grain protrusion sharpness by using profiling wheels, have contributed positively ground surface conditions despite relatively rougher topography in comparison profiling. considerable reduction mean roughness depth (Rz) than arithmetical value (Ra) (11% smaller Rz values versus mechanical conditioning) verifies that workpiece underwent less degradation case because forces. Furthermore, wear behavior WED conditioned superior conventionally one.
