A drilling apparatus includes an attachment box configured to couple to a machine tool. The drilling apparatus facilitates formation of a hole in a workpiece with workpiece structure that results in a large offset distance from a start location of the hole to the machine tool, restricted access to the start location, or both. The drilling apparatus includes a bearing housing coupled to the attachment box. The bearing housing includes a pair of bearings. The drilling apparatus includes a shaft position through the bearing housing to couple to the bearings. The shaft includes an end effector interface configured to couple to one or more end effectors of the machine tool at a first end of the shaft. The shaft includes a tool interface configured to couple to a tool at a second end of the shaft. The drilling apparatus also includes an offset foot coupled to the bearing housing.

The present invention relates to a method for working of a work piece, comprising the step of a) providing a template (1) with at least one opening (4, 6, 8, . . . 32) to the work piece (2), b) providing a work tool (70) at the opening (4, 6, 8, . . . 32), c) determining a distance (a) between a fixed reference (17, 116) for the tool (70) and a surface (118) of the work piece (2) facing the template (1), d) collecting the determined distance (a) into a memory (126), e) vibrating a rotary cutting tool (68) on the work tool (70) by means of a vibrating means (77); and f) working the work piece (2) based on said collected distance (a). The present invention also relates to a system for working and measuring objects comprising a computer (128) including a computer program (P) for carrying out the method. The present invention also relates to a computer program (P) and a computer program product for performing the method steps.

A method of recutting the surface of a wheel includes mounting the wheel on a rotatable mount, moving a probe across the surface of the wheel between an outer radial position and an inner radial position to obtain a radial surface profile and rotating the wheel about its axis on the rotatable mount. During rotation of the wheel, the position of a cutting tool with respect to the surface of the wheel is controlled to recut the surface of the wheel in accordance with the cutting profile. The wheel is tagged with a unique wheel identifier, and the unique wheel identifier is recorded into a database in association with an indication of an amount of material which has been removed from the surface of the wheel.

A processing tool includes a tool body having a front end surface, a rear end surface, at least one side surface connecting the front end surface and the rear end surface, and a first coupling part extending between a first end and a second end. The first end is disposed at the rear end surface, the first coupling part being one of a female coupling part and a male coupling part. The first coupling part includes a first identification marker having identification information of the processing tool. A processing tool assembly is also provided, wherein the first coupling part is arranged to be coupled to a second coupling part. The first identification marker is positioned at the first coupling part such that it is positioned in an interface between the first coupling part and the second coupling part when the first coupling part is coupled to the second coupling part.

The disclosure relates to a tool part for a cutting tool having an identification marker arranged at the tool part, wherein the identification marker is a unique machine readable code associated with individual dimension information data. The individual dimension information data includes at least one individually measured dimension of the tool part as measured when manufacturing the tool part that will change while wearing the tool part. The disclosure further relates to a system, a method and computer program product for utilizing an identification marker on a tool part for a cutting tool, for determining a tool wear of the tool part.

An ultra-precise boring cartridge and an adjustment device is disclosed. The boring cartridge includes a cam, a cam follower contacting the cam by a sloped portion, and a spring arrangement exerting a biasing force against the cam follower. The adjustment device includes a graduated dial affixed to an annular sleeve having a hexagonal-shaped end engaged with the boring cartridge. In an embodiment, a dial of the boring cartridge is rotated in increments of about 3.6 by the adjustment device, which causes movement of about 0.005 mm of the cam in a X-direction and movement of about 0.001 mm of the cam follower in a Y-direction, thereby selectively adjusting a machining radius of a cutting insert mounted on the cam follower.

An operational control method is provided for a machine tool that includes a plurality of tool holders with a cutting-tool. The machine tool relatively moves the tool holders with respect to a workpiece to process the workpiece. The operational control method includes determining whether an abnormality has occurred in the cutting-tool during a processing or not, determining whether a simultaneous processing in which at least two or more of the tool holders perform the processings to an identical workpiece is being performed or not and whether the cutting-tool having the detected abnormality is the cutting-tool that is performing the simultaneous processing or not when the abnormality is detected, and causing the tool holder with the cutting-tool having the detected abnormality to take an abnormality avoidance operation and another of the tool holders to take a response operation based on a determination result at the determining of the simultaneous processing.

A removable assembly (38) comprising an information holding unit (36). The removable assembly is positionable in a material object (2), such as a tool, tool component or part, machine, machine component or part, device, etc., and can be removed therefrom by fluid pressure whereby the material object can be subjected to processing that would otherwise cause damage to, or destroy, the information holding unit (36).
