Figure 3. Dynamic rounding loop at grinding position in through-feed centerless grinding system. The characteristic equation of the system at the grinding position, L, can be expressed as follows: 1 + F L ( s ) G L ( s ) = 0. (5) F L ( s ) = Z c s ( 1 − e − 2 π s ) 1 − ε 1 ( L ) e − φ 1 s + Z c r ε 2 ( L ) e − φ 2 s.
