A. Munozruiz et al., A COMPARISON OF 3 METHODS OF ESTIMATING DISPLACEMENT ON AN INSTRUMENTED SINGLE PUNCH MACHINE, Drug development and industrial pharmacy, 21(2), 1995, pp. 215-227
In this paper a determination of the possible sources of experimental
errors of displacement measurements by an instrumented single-punch ma
chine and their repercussion in compression parameters has been accomp
lished. Also, elastic deformation of punches and other parts of the ma
chine was evaluated using three different methods. One of these, based
on the strain gauge response as measure of punch deformation it is pr
oposed as a novel method to correct displacement measurements by instr
umented machines.
