摘要： Method and apparatus for determining present machining height during machining of a workpiece includes an analog resistive sensor, a discrete resistive sensor and a resistive integrity sensor. Analog sensor preferably has a plurality of resistive elements. Discrete sensor includes contact break points on resistive legs, each leg having a different resistive value to create a step-wise incremental change in resistance of discrete sensor as contacts are lapped away. Integrity sensor has resistive value in fixed relation to resistive value of discrete sensor such that ratio is indicative of integrity before machining. Invention enables use of electronic lapping guide with electrically conductive lap without shorting out. Discrete sensor value used to determine location of rear plane of analog sensor and analog sensor value used to confirm identity of break point as part of method for determining current lapping height. Formulae disclosed enable computation of lapping height from measured resistances based on a known height of the analog sensor prior to lapping.

摘要： A lapping guide is provided to determine the position at which lapping of a thin film head to define pole faces should be terminated. Accurate positioning of the lapping guide with respect to the head is insured by forming various elements of the lapping guide during the same photolithographic process steps as those used to form elements of the head. The lapping guide may be used either as an electrical or optical guide. When used as an optical guide, a second lapping guide may be provided as an indicator that more frequency inspection is necessary.

摘要： A measuring device for a machine tool comprises at least one sensor mounted on a supporting arm which is movable with the help of a carriage. To perform an exact measurement of the distance between two diametrically opposed points on a work piece, the supporting arm with the sensor is slidably and/or pivotally mounted on the carriage to displace the sensor in a transverse direction over the machine tool turning center. A folding in and out of the supporting arm which is mounted on a holder on the carriage occurs during insertion into and withdrawal from a storage pocket of a tool magazine. Air cleaning means and cooling means for the sensor and the workpiece are provided. In another embodiment of the measuring device the supporting arm can be approximately U-shaped mounted on a shaft with a sensor on the end of each U-leg for a two point workpiece measurement, can be slid along the holder for the supporting arm and is pivotable about 90 degrees. This holder guides each of the sensors over one side of the work piece. From the displacement distance over the machine tool turning center the workpiece diameter is directly ascertainable.

摘要： The surface of a rotating cylindrical workpiece is monitored by an optical testing unit while the workpiece rotates and is treated by the grinding wheel in a circular grinding machine. The optical testing unit is mounted in part on one sensor of a second testing unit which monitors the diameter of the surface of the workpiece. A transducer and a light source of the optical testing unit are remote from the one sensor and are connected by fiber optic conductors with a head which is recessed into the one sensor and focuses light upon the surface of the rotating workpiece and intercepts light which is reflected by the workpiece. Lubricant which coats the surface of the workpiece in the course of the grinding operation is blown away from such surface in the region where the light beam is focused upon the workpiece.

摘要： A device for controlling the thickness of a contact lens produced on an automatic and computerized numerically controlled (CNC) lathe is disclosed. A sensor control device is incorporated on a lens lathing machine for engaging the front surface of a lens button upon which the convex surface of the contact lens is to be machine lathed. Immediately upon contact between the sensor and the front surface, the sensor provides for breaking an electrical circuit in the lathe controller providing for automatic position registration of the lens button front surface relative to the cutting tool and its pivot point, and a lens of desired center thickness and power curve radius is subsequently generated. Close tolerances and high repeatability are domonstrated in contact lenses lathed generated by these principles.

摘要： A method and apparatus for measuring a dimension of a workpiece mounted on a numerically controlled machine tool having a probe for sensing the surface of the workpiece, an automatic means for moving the probe relative to a datum, the automatic means including a first measuring means for producing a signal defining units of distance corresponding to the relative movement of the probe with respect to the datum, and a second measuring means coupled to the first measuring means for accumulating a count corresponding to the relative movement of the probe in respect to the datum. The actual position of the workpiece surface is determined relative to a nominal position thereof, the nominal position being at a known distance from the datum. According to the method the probe is moved to a first position which is one of the actual and nominal positions of the workpiece surface. Operation of the second measuring means is initiated to begin a count of the units of distance defined by the signal from the first measuring means when the probe attains the first position. The probe is then moved to a second position which is the other of the actual and nominal positions of the workpiece surface. The count in the second measuring means is terminated when the probe attains the second position. The count accumulated by the second measuring means on termination thereof defines the actual distance of the workpiece surface from the nominal position.

摘要： The subject invention involves a device for sensing the depth to which a worn railroad wheel must be machined in order to reclaim the wheel tread and flange contour. The device consists of an assembly of gaging elements mounted on a support block which is, in turn, mounted on a guide rail for radial movement into contact with the wheel tread. The gaging elements include a flange edge contactor slidably mounted on the support block, a tread contactor slidably mounted on the flange edge contactor, and a flange contacting finger pivotally mounted to the tread contactor. In operation the assembly is moved radially toward the wheel until the wheel tread is contacted. The tread contactor thereafter retracts, causing the flange contacting finger to engage the gaging point on the wheel flange. Further, downward movement of the assembly causes the flange edge contactor to move into engagement with the wheel. Appropriate encoders are connected to the gage assembly to generate pulses which indicate the position of the flange edge and the new diameter to which the wheel is to be machined.

摘要： A back pressure gaging circuit is disclosed of the type wherein gage tooling provided with one or more fluid jets disposed to be directed at a surface of a workpiece, with variations in the distance between the gage tooling and the workpiece causing variations in the effect the workpiece has on the pressure upstream of the jet, which effect is utilized to measure this distance. In the present invention, the pressure upstream of a fixed restriction which is in turn upstream of the gage tooling is adjusted so as to maintain a constant pressure at the reading head through variations in distance to the workpiece. The variations in pressure upstream of the restriction are then utilized to measure the variations in distance to the workpiece.
