Feasibility Analyzing of a New-style Inside and Outside Round Lathe about Piston Rings

Inside and outside rounds of piston rings are heterogeneous surfaces, which require high precision in size. This article begins with the data features of the piston ring section, analyzes the technical difficulties in piston ring processing. What's more, puts forwards a scheme which complete numerical control turning of piston rings in the way of adopting AC servo motors to drive the mechanical structure of the ball screw and carries out design, calculation, emulation about some major parts. At last, it proposes data retrieval methods of numerical control programming. The theoretic calculation and emulation prove the scheme flexible, which approach the demands of processing precision and efficiency in piston ring production.
