Tail stock study. Quarterly report, April--June, 1970.

摘要

This project is to investigate and determine minimum, safe, and reproducible tail stock forces appropriate for use in the fabrication of creep and tensile specimens for HE. The survey conducted revealed that tensile specimens were machined with a tail stock force of approximately 60 psi. The tail stock force was reduced to 6 psi by incorporating center holes in the machining operation. Comparison tests between tensile specimens fabricated with a tail stock for ce of 10 psi and 50 psi clearly indicated that the specimens fabricated with 50 psi of tail stock force received some damage.
