摘要:
An adjustable radius gauge for measuring and or checking the radius of parts previously made or while forming radii in the process of being formed, as experienced in the bending in a press brake or rolls, dishing presses, spinning, bulging or shrinking machines or by hand or by whatever process of bending or contouring may be used. Also as a layout tool to layout materials in any trade requiring radius layout and required marking.

A method of determining a radius of a cutting end of a tool for a turning machine using a touch probe is provided. One of the cutting end and the touch probe is movable relative to a reference frame having a first axis and a second axis and having a reference point trackable in the reference frame. The method comprises establishing a first contact point and recording a first coordinate of the reference point on the first axis; establishing a second contact point and recording a second coordinate of the reference point on the second axis; establishing a third contact point and recording a third coordinate of the reference point on the first axis and a fourth coordinate of the reference point on the second axis upon contact; and determining a radius of the cutting end based on the first, second, third and fourth coordinates.

An arithmetic control circuit (52) is configured to bring the measuring element (38) for a lens into contact with at least two points (measurement points P1, P2) of one of two refracting surfaces of the lens Lm held in the lens holder by controlling the measuring element shifter (driving motor 6), obtain the coordinates of the two points according to the detection signal from the position detector (linear scales 24, 40), and obtain a curve value Cv of one refracting surface of the lens from the difference of the coordinates of the two points.

A method of evaluating material properties of polymeric materials includes making one or more material samples or slabs, with each of the samples or slabs having a pair of material layers in contact with one another. The layers are layers of organic matrix polymer material that have different characteristics from each other, for example having a difference in composition and/or cure characteristics. Characteristics of the test slabs and the interface between the layers can be determined by examining curvatures of the test slabs. A number of samples may be made up having the same material in a first layer, and range of different materials in the respective second layers. The range may cover a range of various material compositions and/or cure characteristics.

A tool for measuring an object having a circularly curved surface provides a generally rectilinear body defining a V notch having two converging sides meeting at an apex and an angulated wedge track. A wedge movable along the wedge track and across the V notch intersects a bisector of the V notch at an angle other than perpendicular. Sides of the V notch and a measuring edge of the wedge simultaneously contact the circular curve at three equally spaced apart positions along the circumference of the circular curve. Measuring indicia on the body adjacent the wedge track allows determination of the lateral movement of the wedge along the wedge track. The distance the wedge moves on the wedge track is equal to the radius of the circular curve.

An apparatus for checking the diameter and the roundness of pins, for example crankpins and main journals of a crankshaft rotating about its main axis of rotation (8), includes a measuring device, coupled to a Vee-shaped reference device (20) and including a feeler (17) axially movable along the bisecting line of the Vee, or a direction slightly sloping with respect to it, and a movable support device for the reference Vee. The support device includes a support element (5) and a coupling mechanism that carries the reference Vee (20). The coupling mechanism includes, for example, two support sections (e.g. parallelogram structures) in series and enables plain translation displacements of the reference Vee. While checking an orbitally rotating crankpin, the Vee-shaped device maintains proper contact with the surface of the pin by virtue of the force of gravity, and the angular arrangement of the direction along which the feeler (17) moves remains substantially unchanged.

An apparatus for measuring the curvature radii of spherical and cylindrical surfaces is provided. The apparatus comprises a base, a probe and four ball rings of the same size, wherein the four ball rings are provided on the base and arranged into a square having a side length C. The probe is upward and downward movably mounted on the top surface of the base at the center of the square. There is also provided a method for measuring the curvature radii of spherical and cylindrical surfaces, wherein a ball-ring-distance is equal to C for the cylindrical surface or is equal to .sqroot.2C for the spherical surface.

摘要:
Disclosed is a multi-purpose measuring gauge in which three probes are secured to and movable with respect to a T-shaped housing. Two outer probes are secured to members which are slideable along parallel slots in the housing. The probe members comprise a rack and are moved by a pinion. The pinion is coupled to a micrometer caliper. The dual travel of the rack and pinion thereby retains the respective relationship between the two probes and the third probe, which is disposed equidistant between the two probes. The stem of the T of the housing has therethrough the third probe. All of the axes of the probes are parallel. The ends of the two outer probes are co-planar. The third probe is moved perpendicularly with respect to that plane by means of another micrometer caliper rotatably secured to the housing. The facing sides of the two outer probes are planar to aid in making measurements. Indicia on each caliper provides a direct reading to make a variety of measurements.
