Theoretical Studies and Simulation Analysis of the Time Domain Non-Symmetrical Configuration Two-Probe Method for Roundness Error Separation

Theory and Technology of The Single-Probe Two-Step Method to Separate Error

“…One reason for that is two-probe method causes much harmonic loss in frequency domain [3,[21][22][23]. In addition, the time domain symmetrical configuration two-probe method can only improve the precision of the single probe method to a certain extent, but is not capable of separating nonrecurring random errors of each revolution [21][22][23].The initial values of the shape errors of the time domain non-symmetrical configuration two-probe method must be assumed in advance in the recurrence formulas [21,22]. However, it is difficult to estimate the initial values and theoretical errors are inevitable, which affects the precision of the model.…”

“…Moreover, when measuring by single-probe multi-step method, it requires the error of the workpiece and spindle has good repeatability in the measurement cycle, no probe re-install during measuring, continuous measurement process that can achieve high accuracy. But the measurement cycle is long and it is easily affected by the surroundings [21][22][23].…”
