Additive Indexable Insert Recesses for Flexible Tool Fastening

The patent creates a universal indexable insert design where a single base geometry can be adapted to multiple applications through configurable recesses. The recess can be positioned at different locations and configured with various geometries to accommodate different fastening requirements, making one insert design suitable for multiple cutting applications without requiring entirely different insert designs for each application.

The insert design segments the fastening function from the cutting function. The recess structure is separated as a distinct configurable element that can be adapted without changing the overall insert geometry or cutting edges. This allows the same insert body to serve multiple purposes by simply modifying the recess configuration.

The patent replaces traditional mechanical subtractive manufacturing methods (milling, drilling, grinding) with additive manufacturing technology. The recess is created by selectively not forming material in specific regions during the additive layer-by-layer construction process, eliminating the need for subsequent subtractive operations and significantly reducing production time while maintaining geometric precision.

The recess geometry is prepared and integrated into the insert design before the final manufacturing process. By using additive manufacturing, the recess is created during the primary construction process rather than requiring preliminary design followed by separate subtractive manufacturing steps, thereby eliminating redundant operations.
