Abstract
This Master Thesis has been completed at the research and development department of
Sandvik Mining and Construction in Perth, Australia. The scope of it, specified by
Sandvik, includes two main task, both part of greater product development processes at
Sandvik Mining and Construction.
The first task is an incremental improvement of an existing product. Sandvik believes
their patented Dual Property (DP) carbides could replace the standard carbides in their
RC hammers and prove more wear resistant. DP carbide prototypes are developed within
this thesis and testing for evaluation is initiated.

This Master Thesis has been completed at the research and development department of
Sandvik Mining and Construction in Perth, Australia. The scope of it, specified by
Sandvik, includes two main task, both part of greater product development processes at
Sandvik Mining and Construction.
The first task is an incremental improvement of an existing product. Sandvik believes
their patented Dual Property (DP) carbides could replace the standard carbides in their
RC hammers and prove more wear resistant. DP carbide prototypes are developed within
this thesis and testing for evaluation is initiated.
Sandvik seeks to grab market shares from their main competitor, market leader Boart
Longyear (BL), in the wireline drilling segment by improving their latch for their core
barrel. The purpose of the second task of this thesis is therefore to develop a prototype of
a latch as good as, or better than, BL’s. That is, another incremental improvement of an
existing product. The new latch also has to be compatible with BL’s latch body. The
prototype is developed through reversed engineering of BL’s latch, which is protected by
a patent.
Regarding the DP carbides, the prototypes developed worked properly, but the initial
testing gave a surprising result. It indicates that the patented DP carbides are less wear
resistant than the standard carbides and perform worse. However, the test data is not
extensive enough to be able to draw any valid conclusions. Instead, more tests are
needed.
Regarding the latch, several prototypes, both physical and analytical were developed. The
scope of this thesis ends with a satisfying beta prototype which will be used to
manufacture a preproduction prototype. The task was to be solved with a cam solution
and reversed engineering was employed. (Less)
