Benchwork and Layout Operations 241

Benchwork and Layout Operations provides a detailed overview of the various benchwork and layout processes that operators often need to perform during manual machining. Layout is the process of marking a workpiece prior to cutting in order to have a visual guideline during cutting operations. Benchwork includes various cutting processes that machinists complete by hand rather than on a machine when creating part features that require less power and force. Common benchwork operations include hand tapping, hand reaming, hand filing, and engraving. Manually machined workpieces often require benchwork and layout operations. As a result, benchwork and layout are essential skills to have for any manual mill operator. A knowledge of not just how, but also when and why to perform benchwork and layout operations is key to becoming a skilled manual machinist and producing precise, accurate manually cut parts.
