Abstract: A system and process for performing a crimping operation by which a fitting is crimped to the end of a fluid conduit, and which automatically compensates for one or more variables that can lead to out-of-tolerance crimp diameters, particularly fitting spring-back and crimper deflection.

The crimper comprises a plurality of dies and an actuator for contracting the dies around the fitting to obtain the targeted crimp diameter for the fitting. The system and method further includes a unit for attaining the targeted crimp diameter by automatically compensating contraction of the dies for spring-back of the fitting during crimping and/or deflection of the crimper during crimping.

Abstract: A method of forming blind holes in a sheet material is provided. The method includes punching the sheet material to define a hollow projection through the material and shearing a layer of material from the sheet material to form a sealed end over an opening of the hollow projection to form the blind hole. Further processing of the sheet material may be required depending on the desired diameter of the blind hole. Such further processing includes enlarging the hollow projection to a desired diameter of the blind hole and shearing the layer of material with several tapered pins with progressively decreasing diameters. As the scaled end formed is likely to have an uneven surface, the sealed end may be flattened to render a more refined appearance.

Abstract: A process for manufacturing a surgical needle incorporates at least one pressing operation which, preferably, in conjunction with a trimming and/or etching process, ultimately forms the sharpened needle end. The grinding operation in the preferred process does not produce the primary sharpened edges of the needle, but, rather is incorporated, in one instance, to reduce excess needle material prior to the pressing operation. Consequently, the amount of flash material generated during pressing is substantially reduced. This feature desirably enhances the subsequent trimming and etching operations, and produces a needle which is extremely sharp, durable and exhibits an improved retention of sharpness over periods of prolonged use.
