An incremental step toward modern power routers was the foot-pedal operated router, such as the Barnes Former/Shaper, available in 1877. [2] Barnes patented a reversible rotary cutting head in 1889. [3] The first portable power router was patented in 1906 by George Kelley and marketed by the Kelley Electric Machine Company. [4]
A rotary cutter is a tool generally used by quilters to cut fabric.It consists of a handle with a circular blade that rotates, thus the tool's name. Rotary cutter blades are very sharp, can be resharpened, and are available in different sizes: usually smaller blades are used to cut small curves, while larger blades are used to cut to straight lines and broad curves.
Two archetypes of this type of mower are the Bush Hog which is made by Bush Hog, Inc. [1] of Selma, Alabama, and the Flex-Wing by RhinoAg of Gibson City, Illinois.The formal name for this type of implement is a rotary cutter or rotary mower, although it differs from mowers in that it does not cut with a sharp blade, but rather severs with an intentionally very dull wedge-like blade.
Rotary cutters mounted on a swather. Rotary mowers, also called drum mowers, have a rapidly rotating bar, or disks mounted on a bar, with sharpened edges that cut the crop. When these mowers are tractor-mounted they are easily capable of mowing grass at up to 10 miles per hour (16 km/h) in optimal conditions.
Burrs are a rotary analog to files that cut linearly (hence their alternate name, rotary files). They share many similarities with endmills and router bits , with the notable distinction that the latter typically have their toolpaths dictated by the machine, while burrs are frequently operated in a freehand manner.
