dimKerf

dimKerf is a term used in design and manufacturing to denote the dimensional kerf—the amount of material removed by a cutting operation that affects the final size and fit of parts. The concept is important in CAD/CAM workflows where parts must meet tight tolerances after processing.

In practice, dimKerf is used as a parameter in software and engineering notes to compensate for kerf when laying out parts, selecting tools, and planning joints. It can be associated with a specific cut, tool, or operation and used to offset geometry to achieve the intended final dimensions.

Kerf width is influenced by multiple factors including tool geometry, material properties, and process parameters such as speed, feed, and lubrication. Because kerf can vary over time and across machines, dimKerf is often treated as an estimate or input that may be iteratively adjusted.

Applications include woodworking, metal fabrication, and laser or waterjet cutting. For example, in joinery, engineers may offset mortises or tenons by dimKerf to ensure a precise interlock; in sheet metal, dimKerf helps compensate for the removal when forming bends or making cuts.

Limitations include kerf drift due to tool wear, temperature, and setup inaccuracies. Therefore, dimKerf is typically accompanied by validation steps such as test cuts, measurement of scrap, and tolerance analysis to ensure final assembly meets specifications.
