摘要:
A guide rail (21) having a guide surface for guiding sliding movement of a movable body (5) is monolithically formed on a base (2) of a measuring machine (1). A coating film for rust prevention is formed on the guide surface. With this feature, it is not necessary to attach the guide rail (21) as a discrete member to the base (2), so that a number of steps in the manufacture process and the production cost can be reduced. Further as the base (2) and the guide rail (21) are made of the same material, the bimetal effect does not occur, which insures the stability of the base (2) against changes due to aging.

A measuring system includes a coordinate measuring machine for driving a scanning probe and a host computer. The host computer includes a compensation table (53) and a profile analysis unit (54). The compensation table stores, as compensation data, compensation coefficients to correct counter values of a probe counter (415), and compensation radiuses “r” to the workpiece surface concerning central coordinate values of a contact portion, for respective contact directions. The profile analysis unit has a contact direction calculation unit (542), a compensation data selection unit (543), a compensation calculation unit (544). The contact direction calculation unit calculates the contact direction along which the scanning probe comes into contact with a workpiece W, and the compensation data selection unit selects compensation data set up in the compensation table based on thus calculated contact direction.

An object of the invention is to provide a position measuring apparatus which can execute a stable accuracy assurance at a high accuracy against a deterioration with age and a temperature fluctuation of the apparatus while making a correction of an existing volumetric measuring accuracy effective. In order to achieve the object, in accordance with the present invention, in a position measuring apparatus which measures a target position within a specified coordinate space with respect to a predetermined reference surface (4) on the basis of a coordinate system so as to compensate errors, there is provided a detector (18) for measuring whether or not a change is occurred in a relation with respect to the reference surface (4), in a movement executed by a moving machine (8), and there is further provided with an error corrector (20) for correcting at least any one of a compensation parameter compensating a positional coordinates by an error compensator (16) and a positional coordinate compensated by the error compensator (16), on the basis of an amount of change of a relation measured by the detector (18), in the case that the change is occurred.

On a roadbed layer (4) is formed a cushion layer (5) of 50 mm to 200 mm in thickness which is formed by using elastic chips alone or in mixture with sand, each elastic chip being formed of elastic material and having a size of 7 mm to 0.05 mm, preferably 2 mm to 0.5 mm and a specific gravity of 1.8 to 3.5. The cushion layer (5) contains elastic chips of 3 wt % or more. The elastic chips are formed by mixing a material selected from the group consisting of synthetic rubber, natural rubber and synthetic resin with a specific gravity adjusting material of inorganic powder having a specific gravity of 3 or more.
