<p>ENGLISH ABSTRACT: When three dimensional machining is performed with a numerically controlled milling machine, then it is necessary to make use of cutter centre point programming because radius correction for these machines is possible in two dimensional context only. With ,:he rapid development of numerically com:rolled units it is possible now to use parameter programming for the development of three dimensional spaces which was possible only wi til computer aided design software some two years ago. An exceptional visualization of .the relationship between cutting surface and cutter position as well as a sound mathematical background is necessary to enable accurate programming of three dimensional spaces.</p><p>AFRIKAANSE OPSOMMING:Wanneer driedimensionele snywerk met 'n numeriesbeheerde freesmasjien gedoen word, is dit nodig om van snyermiddelpuntprogrammering gebruik te maak, omdat snyerradiuskorreksie vir hierdie masjiene slegs in tweedimensionele verband bestaan. As gevolg van die snelle ontwikkeling van numeriesbeheerde eenhede is di t nou moontlik om met behulp van parameterprogrammering driedimensionele ruimtes te ontwikkel wat twee jaar gelede slegs met rekenaargesteunde ontwerpprogrammatuur moontlik was. Vir die akkurate programmering van driedimensionele ruimtes is 'n besondere visualisering van die verband tussen snyvlak en snyerposisie, sowel as 'n grondige wiskundige agtergrond, nodig.</p>
