Speed non-circular piston turning using extracted Computer Numerical Control (CNC) approach high

Abstract

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 the principles of an Extracted Computer Numerical Control (ECNC) solution which can be used on existing Computer Numerical Control (CNC) machines. Test results on an emulated system will be furnished. © 2004IEEE.
