Comparison of Vee notch and U notch response

We have historically used the EDM u-notch for our calibration reflector when testing nuclear-grade zirconium rod. The rod has diameter of 8 to 25 mm, with notch depths of about .25mm. We recently have had a number of customers request the use of the vee notch for standards on new orders. Is there anyone who knows of comparison data on the responses from vee and U notches? I would greatly appreciate being pointed in the right direction for that information.

Re: Comparison of Vee notch and U notch response
David,

PH Tool Reference Standards manufactures EDM notch standards for NDT. We machine both "U" and "Vee-shaped" notches on ODs (and even IDs), oriented longitudinally and circumferentially. I have no response data cpmparing the two types, but would be glad to discuss the machining of various notch types on your supplied zirconium rod.
