A cutting tool for metal cutting includes a tool body having an insert seat and a recess formed therein. The tool body further includes vibration damping means. The vibration damping means have a cantilever member, the cantilever member being adjacent to the recess of the tool body. The cantilever member has a cantilever beam and an end mass, wherein the cantilever member extends between a fixed end and a free end. The fixed end is permanently connected to the tool body. The cantilever beam extends from the fixed end and the end mass extends from the free end.

A rotary milling tool has a tool holder and a milling head releasably attached thereto. The milling head has a plurality of angularly spaced apart peripherally disposed cutting edges which form an effective cutting edge. The milling head has a head through recess opening out to the head forward and rearward surfaces. The recess includes a centering region and a driven region, the driven region being axially forward of, and non-identical to, the centering region. The driven region has at least one driven surface facing opposite a rotational direction. The centering region has at least one radially inwardly facing radial centering surface located axially rearward of, and radially outward from, the at least one driven surface. The two opposing extremities of the effective cutting edge define two parallel planes respectively between which both the at least one driven surface and the at least one radial centering surface are disposed.

A tool body and at least one cassette for a milling tool. The tool body includes at least two identical insert seats, each insert seat being configured to support a cutting insert arranged to be mounted therein. At least one side contact surface is provided in each insert seat for supporting a bottom support surface and at least one side support surface of the cutting insert. The cassette has a peripheral side surface including at least one side support surface and at least one insert seat configured to support a cutting insert. The at least one side support surface and a bottom support surface of the cassette are configured to be supported by the at least one contact surface of any one of the insert seats of the tool body, the cassette being configured to be detachably mounted in any one of the identical insert seats of the tool body.

A hardware fastener with a movable threaded element suspended within a cavity formed in a body. The movable threaded element has an internal surface with threads for cooperating with a threaded fastener. The movable threaded element is suspended in the cavity by the one or more spring-like members such that an area, A, of reduced stiffness is created in the cavity proximate the movable threaded element, thereby allowing the movable threaded element to move a predetermined distance within the cavity when torque is applied to the threaded fastener. The one or more spring-like members store elastic potential energy to prevent the loss of pretension of the threaded fastener that can be caused by heat or vibration. The invention also eliminates the need for a torque wrench when tightening the threaded fastener to a specified torque value.

A machine for milling pavement such as a rotary mixer or road planer includes a cutting rotor that is vertically adjustable with respect to the frame and that is accommodated in a rotor enclosure. The milling machine may be associated with a visual camera network having one or more cameras located about the milling machine with a field of view toward the rotor enclosure and work surface. An image augmentation system can generate a reference line augmentation to superimpose over one or more visual images obtained by the cameras and display the augmented images on a visual display.
