Abstract
The parametric approach to creating designs from a generalised model is discussed. The technique is extended to the manufacture of transfer port cores for two-stroke internal combustion engines. Bi-cubic patches representing each of the three-dimensional sides of the transfer port are constructed from a parametric model using the minimum amount of information. A postprocessor then creates a CNC program from the design data and enables the manufacture of cores for the casting of cylinder blocks containing the transfer ports, The complete process is illustrated by an example which takes a particular configuration through to final manufacture.
