摘要： An auxiliary air bearing system (50) for reducing friction in mechanical bearings (41, 42) to improve repeatability of measurements on a coordinate measuring machine (10). The air bearing system (50) and mechanical bearings (41, 42, 43) support a moveable carriage (30) on a base (20). The air bearing system (50) comprises an air pad assembly (70) mounted to the carriage (30), an air system (80) supplying air under pressure and a rail system (60) mounted to the base (20) with the air pad (70) including a compressed spring (76) captivated therein. Air under pressure is directed between the air pad assembly (70) and the rail system (60), causing the air pad assembly (70) to lift from the rail system (60) and the base (20). The air bearing system (50) and the spring (76) reduce the effect of any irregularities on the rail that would otherwise cause measurement errors. The air bearing system (50) is preferably mounted obliquely to two of the mechanical bearings (41, 42) so that a single air bearing assembly reduces the friction in the mechanical bearings supporting the carriage in two directions.

摘要： A probe for an additive manufacturing system includes a probe body having a first air port therethrough between an inlet and an outlet, and a location sensing probe extending from the probe body. The location sensing probe includes a probe end and a probe bar, the probe bar coupled between the probe body and the probe end, and a channel surrounding the probe bar, the channel having an inner tube having an inlet proximate the probe body and an outlet proximate the probe end. A method of determining a position of an item being printed in an additive manufacturing system, includes probing the position with a location sensing probe having a resolution finer than a print resolution of the print head.

摘要： A method and apparatus for calculating distance in an assembly operation. The method comprises the steps of providing an assembly comprising a first part, a second part and driver means coupled to the first part. The driver means are arranged to selectively move the first part relative to the second part. The method also includes actuating the driver means to selectively move the first part between a first known position and a second position and registering speed and/or acceleration data of the driver means between the first known position and the second position. The time interval for the first part to move between the first known position and the second position is measured. The distance moved by the first part between the first known position and the second position using the measured time interval and the data registered from the driver means can then be calculated.

摘要： The invention contemplates a pneumatically driven piston as a preloading device, continuously urging the movable part (11) of a probe head into precise seating engagement with its fixed bearing (10), (12) in the housing of the probe head. The piston is movable in a cylinder (4) that is supplied with variable regulated pressure determined by a controlled regulating valve (16). Different contacting forces can be automatically and rapidly adjusted by the control system (18) of a coordinate-measuring machine to which the probe head is mounted, and the probe head can be tared to compensate for the different individual weights of successively different probe pins that are used in a given program of multiple-point coordinate measurements on a workpiece.

摘要： Methods and apparatus for measuring the position of an object relative to a reference are disclosed. In an arrangement, a pressurized fluid is used to drive rotation of a cylinder around a piston and to bias the cylinder longitudinally. Ducts are provided in the cylinder and arranged so at to provide pulses of the fluid out of the cylinder through a reading port, the pulses being such as to uniquely identify the position of the cylinder relative to the piston and thereby of the object relative to the reference.

摘要： A non-contacting gauge for measuring small variations in the surfaces of objects comprises:(a) a chamber separated into two sub-chambers by a vibrating diaphragm,(b) a nozzle for each sub-chamber,(c) a reference surface adjacent to one of the nozzles, and,(d) a frame holding the chamber and reference surface moveable relative to the surface to be gauged and adapted to bring the other nozzle into the vicinity of the surface.The gauge is a versatile instrument which, while particularly suitable for measuring changes in the dimensions of geological core samples to determine residual strains, is also suitable for a range of measurement problems.
