Arc Radius Measurement of Aerospace Fasteners
Fasteners’ fixture and positioning
The TIMI-series’ measuring repeatability for R0.5 is up to ±1µm, better than that of the profilometer. Their precise and fast measurement performances meet the needs of full inspection for aerospace fasteners.(Precise-Type: TIMI34P; Auto-Type: TIMI34RZ)
Background of the Application
The tolerance of arc radius is particularly strict (a few microns in general) due to the mechanical strength requirements of aerospace fasteners. Traditional measuring tools like profilometers are hard to meet the requirements of measuring repeatability. As the way of probe operation requires well-trained operators, and the price and maintenance costs are also high, so it is not appropriate for common use of fasteners measurement.
The precision-type TIMI 30P or auto-type TIMI 30A image measuring instrument can automatically measure the Arc by using a quick button once the fastener is properly clamped in a fixture.
The measuring repeatability of the Fillet R0.5 reaches ±1µm
Various "select-measure" quick buttons are available to measure the R value in seconds
TIMI-series Measuring Machine can precisely and quickly measure variety of arcs. Its measuring repeatability is better than that of the profilometer that meets the needs of full inspection for aerospace fasteners.
