Abstract

The work outlines a methodology which can be applied to CNC machines in order to establish the control system gains for minimum contouring errors. Steady state and transient errors are considered using a ‘Contisure’ instrumentation system which enables the radial dynamic errors of a circular profile to be readily established. Practical measurements are undertaken on a Takisawa three axis machining centre with Fanuc 6M controller and examples of these results are given.
