Preparing Cutting Edge with Wet Abrasive Jet Machining Current investigations reveal that the performance of cutting tools is significantly improvable when preparing the cutting edges. The average cutting edge [...] rounding describe the resulting micro-shape of the cutting edge after the preparation. The control of both parameters enables the set-up of the tool’s cutting edge with a targeted and application-oriented shape [...] machining with respect to the cutting edge preparation. In this context, fundamental knowledge of interrelationship between the abrasive jet and the material removal at the cutting edge has to be gained and considered …

grinding technology and which direct the cutting fluid specifically in the direction of the cutting edge of the tool. Increased flow speeds in the area of the cutting edge corners improve heat dissipation from [...] lower cutting edge temperatures and considerably longer tool lives compared to standard tools. These effects were particularly pronounced at high cutting speeds. A significant reduction of cutting fluid [...] fluid coking behind the main and secondary cutting edges indicates an improved cutting fluid supply in these areas, which leads to more effective cooling and lubrication. This can also be proven by the significant …
