Abstract
A rotatable cutting tool with colored visual warning is provided. The cutting tool includes colored portions of at least two different colors. When the cutting tool is rotated above a predetermined speed, the individual colors are not separately discernable but instead appear as an apparent or blended color which serves as a visual warning.
Claims27
A cutting tool that is rotated to cut material, comprising:
- structure connected to and supporting at least one cutting edge, so that the structure and the cutting edge rotate together while the cutting tool is rotated to cut the material;
- a recess formed in the structure for rotating with the cutting edge while the cutting tool is rotated to cut the material;
- and
- a plurality of colored portions located in the recess, wherein the colored portions are located so that they rotate along the same path while the cutting tool is rotated, at least some of the colored portions are different colors that are readily distinguishable from one another while the cutting tool is not being rotated, the colors of the colored portions are selected so that the colored portions form an apparent color that is positioned in the path and apparent while the cutting tool is rotated at greater than a predetermined speed, and the apparent color is different from the colors of the colored portions, whereby the apparent color provides a visual indication that the cutting tool is being rotated.
A cutting tool that is for being mounted on a shaft that is connected to a motor, so that the tool can be rotated, by operating the motor, and used to cut material, the cutting tool comprising:
- at least one cutting edge that rotates while the cutting tool is rotated to cut the material, wherein the cutting edge is positioned radially outward from the shaft;
- and
- a plurality of colored portions positioned so that the colored portions and the cutting edge rotate together while the cutting tool is rotated to cut the material, wherein the colored portions are positioned radially outward from the shaft while the cutting tool is mounted to the shaft, the colored portions are located so that they move along the same path while the cutting tool is rotated, at least some of the colored portions are different colors that are readily distinguishable from one another while the cutting tool is not being rotated, the colors of the colored portions are selected so that the colored portions form an apparent color that is positioned in the path while the cutting tool is rotated at greater than a predetermined speed, and the apparent color is different from the colors of the colored portions, whereby the apparent color provides a visual indication that the cutting tool is being rotated.
A cutterhead for having cutter blades mounted thereto and for being mounted to a shaft of a molding machine so that the cutterhead can be rotated by the molding machine and used by a user to cut material, the cutterhead comprising:
- a body having a central axis, a mounting hole extending coaxially with the central axis and between opposite ends of the body, an outer surface extending around the central axis, a plurality of slots that are open at the outer surface and are for respectively receiving the cutter blades, and fasteners for releasably securing the cutter blades in the slots;
- and
- a plurality of colored portions on the body and positioned radially outward from the mounting hole, wherein the colored portions are located so that they move along the same path while the cutting tool is rotated by the molding machine, at least some of the colored portions are different colors that are readily distinguishable from one another while the cutterhead is not being rotated, the colors of the colored portions are selected so the colored portions form an apparent color that is positioned in the path and apparent while the cutterhead is rotated at greater than a predetermined speed, and the apparent color is different from the colors of the colored portions, whereby the apparent color provides a visual indication that the cutterhead is being rotated.
A method of cutting a solid material, comprising:
- providing a cutting tool including at least one cutting edge and a plurality of colored portions, wherein at least some of the colored portions are different colors such that they are readily distinguishable from one another while the cutting tool is not being rotated;
- mounting the cutting tool onto a shaft that is connected to a motor;
- then operating the motor so that the cutting tool rotates above a predetermined speed, so that the colored portions move along the same path and the colors of the colored portions form an apparent color that is positioned in the path and is different from the colors of the colored portions;
- contemporaneously viewing the cutting edge and the apparent color in the path during the operating;
- and
- cutting the solid material by engaging the solid material against the cutting edge during the operating.
A method according to 26, wherein the cutting includes maintaining a rotational axis of the cutting tool at least substantially stationary while moving the solid material further onto the cutting edge.
