PRODUCTION GAGING SOLUTIONS - Fast-Accurate Taper Gages & Applications

Taper specifications
Taper designs may be specified by an included angle and an angularity tolerance; or the slope may be defined as "Basic" and a "form or contour" tolerance applied to the profile. In either case a datum controlling the size of the taper must be located at some point on the taper. Referred to as a "Reference or Datum diameter", this dimension relates the taper to some feature on the workpiece, such as an adjacent shoulder or a theoretical sharp corner at one end of the taper.

Readout selection
Tapers specified with angularity tolerances require readouts the utilize "A-B" and "A-C" calculation functions to display angularity deviations. Tapers utilizing contour tolerances require direct coupled readouts that display the profile tolerance limits at each set of sensors. Micro II Readouts can be conifigured to check either angular deviations or contour toleranced tapers. See table of order codes for taper gages at right.

Two or Three air circuits
Taper gages that incorporate three air circuits allow the user to determine if hourglass or barrel shapes are super imposed on taper profiles. They are preferred on long tapers where this profiling error is most common; however space limitations often prohibit including the third circuits on short tapers.
