I was wondering what people do for calibration of thread wires?
We have several external thread gages that are too large for our calibrated pitch mics. We normally check these gages with thread wires. To pass a typical audit, would it make sense to calibrate the thread wire set we are using for tractability? The OD mics are traceable, but I'd have nothing to show for the wires.
Wire sets are less than the cost of calibration, but I'm not sure these wires are made to any particular spec, like ZZ or X. I supposed I could set a 3 year calibration cycle on our master set. On the other hand, I could send those thread gages out, but that gets more expensive by far than just calibrating the wire set. Or perhaps I can verify the thread wires with a master calibrated Mic?
I think I'd be most comfortable sending them out for calibration and eating that cost if its reasonable.
Any way, what does anyone else think?
Thank you,
