Non‐circular pistons are becoming increasingly popular in internal combustion engines as they facilitate the construction of a more efficient engine. However, at the moment, it is still a very expensive and time consuming procedure to cut non‐circular pistons, owing to practical problems which have yet to be overcome. This paper will examine these problems and highlight an Extracted Computer Numerical Control (ECNC) solution which can be used on existing Computer Numerical Controlled (CNC) Lathes. A high speed linear servo unit is presented as an extracted part of the system. Repetitive control is also discussed in the paper.
