A developer of bespoke metrology systems for the orthopaedics industry has introduced a taper measurement gauge to ensure that tolerances are met and a part identification gauge to verify that the correct parts have been packaged together. Tapers on implants are stringently controlled with tolerances as low as 10 µ. Coordinate measuring machines (CMMs) and air gauges are traditionally used to verify dimensions, but both techniques have drawbacks, according to Trac Measurement Systems Ltd. The CMM is slow and the capital outlay is considerable; the air gauge, on the other hand, is very quick but cost of ownership is high because of the many masters that are needed. The Mechanical Taper Gauge from Trac couples speed with 1-µ accuracy. The use of analogue scanning provides a wealth of data and has the added advantage of outputting straightness.
