The present invention relates to a coordinate measuring machine with a measuring system for measuring a workpiece, a carrier structure for carrying the measuring system and a base plate for supporting the workpiece. The carrier structure is movably guided in at least one direction on the base plate. The coordinate measuring machine also has a first support system with at least three supports for supporting the base plate, a second support system and a control device for controlling the second support system dependent on a force application to the first support system. The present invention also relates to a method for compensating for large workpiece masses on a coordinate measuring machine.

A series of nominally identical production workpieces is measured on a measuring apparatus. To correct for temperature variations, one of the workpieces forms a master artifact, the dimensions of which are known. The artifact is measured on the measuring apparatus at two or more temperatures, producing two or more corresponding sets of measured dimensional values of the master artifact at the respective temperatures. One or more error maps, look-up tables, or functions are generated which relate the measured dimensional values of the artifact to the known dimensions of the artifact. The error map(s), look-up table(s) or function(s) are dependent on the respective temperatures at which the artifact was measured. Correction values derived from the error map(s), look-up table(s) or function(s) are used to correct the measurements of production workpieces in the series. These correction values are determined in dependence upon the temperature at which the workpiece measurements were obtained.

A golf club includes a club head having a volume of greater than about 360 cm.sup.3 and a mass less than 200 g. A shaft attachable to the club head has a tip end, a butt end, and a shaft balance point distance, BP.sub.s, as measured from the butt end, of no more than 19 inches. And the golf club has a mass less than 300 g.

A method, apparatus, and system are provided to monitor and characterize the dynamics of a phase change region (PCR) created during laser welding, specifically keyhole welding, and other material modification processes, using low-coherence interferometry. By directing a measurement beam to multiple locations within and overlapping with the PCR, the system, apparatus, and method are used to determine, in real time, spatial and temporal characteristics of the weld such as keyhole depth, length, width, shape and whether the keyhole is unstable, closes or collapses. This information is important in determining the quality and material properties of a completed finished weld. It can also be used with feedback to modify the material modification process in real time.

A workpiece clamping systems for a measuring machine includes a rotary table disposed in a workpiece rotation axis and includes a chuck for the concentric accommodation of a workpiece, a rotary drive for the rotary table, an upper centering tip mountable or mounted on the measuring machine in the workpiece rotation axis vertically opposed to the rotary table and a lower centering tip mountable or mounted on the rotary table in addition to the chuck for accommodating a workpiece between the centering tips instead of in the chuck, wherein the lower centering tip is provided and formed to be concentrically clamped in the chuck instead of a workpiece, and in that the workpiece clamping system is provided with a conveying device for vertically or vertically and chuck.

A motorcycle frame rack enables a motorcycle frame to be repaired without removing many components from the motorcycle. A motorcycle is positioned on the motorcycle frame rack, secured in place and then the frame is adjusted using chains coupled to towers. A self-centering laser measuring system is able to be used to analyze and measure damage to the motorcycle frame.

In a shape measuring apparatus for measuring the roughness and/or contour of a surface of a workpiece by sliding a sensing pin on a tip end side of an arm on the workpiece, the arm is provided with an engagement mechanism that makes a sensing pin side of the arm removable to a base end side of the arm. The engagement mechanism has two engagement surfaces which face each other and attract each other by a magnetic force. One of the engagement surfaces includes a linear first groove that is in parallel to an axis of the arm and another engagement part that is different from the first groove, and the other of the engagement surfaces includes a first fitting pin that is positioned to be fitted into the first groove and a second fitting pin that is fitted into the other engagement part.

A welding gauge and method of use that allows a user to measure the difference in height between a first material surface with that of a second material surface when they are welded together along the same plane or at an angle. The gauge has a first plate with a foot portion and a bottom reference edge. The first plate is connected to a second plate at an axis of rotation corresponding to a circular measurement scale located on the first plate. The gauge also has a third plate that is attachable to the second and slidably connected through vertical slots located in said second and third plates. The third plate has a bottom contact edge and tolerance indicators along its left and right edges that can align with a tolerance measurement scale located on the second plate and along the vertical slot of the second plate.

A brake wear gauge assembly includes a plurality of wires that is each comprised of a bendable material such that each of the wires is retained in a desired shape for guiding between a brake rotor of a vehicle and a brake pad of a vehicle. A ring is provided that has each of the wires movably disposed thereon thereby facilitating the plurality of wires to be portable. A plurality of feeler gauges is each coupled to a respective one of the wires. Each of the feeler gauges can be inserted between the brake rotor and the brake pad and each of the feeler gauges has a unique measuring thickness with respect to each other. In this way the plurality of feeler gauges can measure a variety of distances between the brake rotor and the brake pad.
