Undercut ⚙️
An undercut in machining and manufacturing refers to a feature or recess in a part that is inaccessible directly from above or below, often requiring special tooling or multi-axis machining to create. Undercuts can be intentional design features, such as grooves, slots, or recesses, or may occur unintentionally in complex geometries where certain areas are shielded by overhanging sections.
An undercut refers to a shape or feature in machining where a recessed or hollowed-out area is created, typically beneath a surface or edge. Undercuts are commonly used to achieve specific design or functional purposes, such as interlocking parts or improving structural performance. However, these features often require specialized tooling and additional attention during maintenance to ensure the integrity of the design. Proper planning and tool selection are critical for creating precise undercuts while minimizing wear and tear on the equipment.
Key Points about Undercuts
Design: Undercuts are often included in part designs for specific purposes, such as creating interlocking parts, grooves, or keyways, or for aesthetic reasons.
Machining Requirements: Since undercuts cannot be reached with standard cutting tools aligned with the primary machining axis, they require specialized tools, such as T-slot cutters, dovetail cutters, or multi-axis CNC machines.
Applications: Undercuts are commonly used in mould making, casting, and parts that require snap-fit or interlocking features. They are also frequent in parts with complex geometries, such as housings and custom fasteners.
Challenges: Machining undercuts can increase production complexity, tool wear, and setup time. Proper planning and specialized tools are essential for achieving precise undercuts without damaging the workpiece.
