Three-dimensional tool compensation for a three-axis turning centre

Modem CNC turning centres are often equipped with powered tooling to enable radial or axial drilling, tapping or milling operations. If the machine to ol is equipped with a fully controlled C-(spindle) axis the prospect of mor e complex milling operations becomes evident. However for such operations, the requirements for tool compensation limit the work which can be achieved . This paper details an algorithm for 3D tool compensation when using a sph erical end milling cutter as a radial tool in such a turning centre.
