The result shows the taper value or diameter change along the length of the impression.
The results clearly show that all holes have very similar taper
values. There is an offset between the impression diameter
value and the actual hole diameter value. However, the
result does show the change in diameter along the length of
the hole.
The largest taper produced with this new technique was a
hole with a diameter of 270 m increasing to a diameter of
335 m over a length of 1 mm. Larger tapers can be produced.
However, in the course of this work, this was not done.
The results of the final test were very positive and showed
that diameter variation is minimised. Hole form and quality
are improved
