Which process uses a long blade mounted in a bow-shaped frame?

The process that utilizes a long blade mounted in a bow-shaped frame is hacksawing. Hacksawing is specifically designed for cutting metal and other materials using a blade that is tensioned within a frame, allowing for precise cutting action. The bow shape of the frame provides stability and support to the blade, which is why hacksaws are commonly used in metalworking applications for making intricate cuts or working in tight spaces.

This method is distinct from the other processes mentioned. For instance, band sawing employs a continuous loop blade that runs on wheels, which is different from the separate, single blade used in hacksawing. Chop sawing typically involves a circular blade that moves downwards to cut through materials, making it suitable for straight cuts rather than the intricate or detailed cuts associated with a hacksaw. Table sawing, likewise, involves a stationary circular blade mounted underneath a table, not a long blade in a frame, thus differentiating it from the hacksawing technique.
