Apparatus and method for determining feedscrew and barrel wear |
摘要 |
An apparatus and a method for determining wear of a feedscrew and barrel combination includes a measuring aperture formed in a wall of the barrel, a gage plug releasably retained in the measuring aperture and having an inner end curved to correspond to a curvature of a surface of the central bore surrounding an inner end of the measuring aperture, and a retaining plug releasably retained in the measuring aperture for maintaining the gage plug in place. When the plugs are removed, the gage plug can be measured for barrel wear and a probe can be inserted into the measuring aperture for determining feedscrew wear. A test bar simulating feedscrew wear is used to calibrate the probe.
