A pre-compensation method of the systematic contouring error for repetitive command paths

D. L. ZHANG,Y. H. CHEN,Y. P. CHEN

Frontiers of Mechanical Engineering 2015, Volume 10, Issue 4,   Pages 367-372 doi: 10.1007/s11465-015-0367-5

Abstract:

For a repetitive command path, pre-compensating the contouring error by modifying the command paththis paper proposes the use of a back propagation neural network to extract the function of systematic contouringFurthermore, by using the extracted function, the contouring error can be easily pre-compensated.The experiment results verify that the proposed compensation method can effectively reduce contouring
