A method of implanting a contact implant includes providing the contact implant, providing a plurality of anchoring implants having a plurality of through openings, placing the contact implant at an implantation location, and introducing a first one of the anchoring implants through a first of the plurality of through openings. Mechanical oscillations are applied, along a first axis, to the first one of the anchoring implants, thereby causing thermoplastic material of the implant to liquefy and interpenetrate portions of the tissue. A second one of the anchoring implants is introduced through a second one of the through openings to bring it in contact with the live tissue. Mechanical oscillations are applied, along a second axis, to the second one of the anchoring implants to cause thermoplastic material to be liquefied. The first and first and second axes are at a nonzero angle to each other.

A method machines or tests a blade for a turbomachine. The method includes: clamping the blade in a clamp such that a point contact or a line contact forms between the blade and the clamp as clamping partners. One of the clamping partners has a lower strength than the other clamping partner and plasticizes in the region of the point contact or the line contact.

A system for supporting workpieces comprises a base and a plurality of support members (1), each support member (1) comprising a plate (11) and means for positioning the plate (11) in relation to the base. In at least some of the support members (1). The means for positioning the plate (11) comprise at least three controllably extendable members (13) arranged for determining the position and inclination of the plate (11) in relation to the base, thereby allowing for controlled positioning of the plate (11) in relation to the base and for controlled inclination of the plate (11).

A fixture for suppressing tool vibration on an outer rim, wherein a pressure claw base, an end face block and a base are installed on the chuck, and the pressure claw is installed on the chuck; a lower pressure plate is fixed on the base, limiting columns and an upper pressure plate are installed on the lower pressure plate, with steel balls and a rubber strip being enclosed in a space formed by the lower pressure plate and the upper pressure plate; and a rubber strip is enclosed in an annular groove formed by a jaw A and a jaw B, and can move radially in the groove. The fixture in the present invention is configured to counteract the vibration of the wheel rim during machining, and thus can effectively eliminate the problem of tool vibration on the outer rim.

The present invention relates to an actively dampened centerless grinding process for a centerless grinding machine having wheels, between which there is arranged a part to be ground, and heads carrying the wheels, which process has moving the wheels closer to one another by applying pressure on the part for the grinding thereof, such that vibrations are generated in the grinding machine due to grinding, measuring the vibrations due to grinding, and introducing, depending on the measurement, an active damping force (F.sub.act) parallel to the force flow of the grinding machine and by means of using an inertial actuator acting directly on one of the heads, such that the vibrations due to grinding are attenuated.

An engine mount device includes a housing, a carrier within a cavity in the housing, and a flexure flexibly connecting the carrier to the housing, with a pin disposed in a hole in the carrier to support an engine. A method of providing isolation in the engine mount device includes transmitting a force from the pin into the carrier; mechanically isolating the carrier from the housing via the flexure; and providing, via the flexure, a higher stiffness in one or more radial directions of the hole compared to a stiffness provided in an axial direction of the hole.

A tool chuck for clamping a tool in a machine tool, having a base body and a sleeve part protruding therefrom, which sleeve part forms a tool holder for fixing a tool shaft in a frictional, nonpositive fashion; a cavity in which a vibration damping component is accommodated is provided in the tool chuck.

A machine tool that cuts a workpiece by a rotary tool includes a tool spindle device that holds the rotary tool in a manner to allow self-rotation with a predefined tool rotational axis Rt as a center, one or more in-machine robots, and a connecting mechanism that attaches the in-machine robot on the tool spindle device so that the in-machine robot moves independently from the rotary tool at a periphery of the tool spindle device with the tool rotational axis Rt as a center.

There is provided a vibration suppression device, a machine tool including the device and a vibration suppression method using the device. The vibration suppression device includes a flexible member having a first position F fixed to the structure to be a fixed end of a cantilever and a second position on a free end side; and a weight attached to the flexible member in the second position. The vibration suppression device has an adjustment mechanism for changing a distance between the first position and the second position. Accordingly, it can effectively suppress vibration of a structure, and that can effectively suppress the vibration by easy adjustment when the characteristic of a generated vibration is different.

A workpiece positioning arrangement comprises a positioning device for positioning a workpiece as well as a decoupling device for the decoupled storage of the positioning device, wherein the decoupling device comprises a carrier element, on which the positioning device is arranged, and a base element, on which the carrier element is supported. For decoupling the dynamic reaction forces of the positioning device on the base element, the carrier element is supported on the base element so as to move freely at least in a certain range, preferably essentially free of counterforces, in a sliding manner.
