4.6. A hydraulic servo system used to control the transverse feed of a machine tool is shown in Fig. P-4.6. Each angular piston of the cam corresponds to a desired reference position x, such that y, = K,4,. The load on the piston is that due to tool reactive force and may be assumed to consist of mass M, friction f and spring with constant K. Draw the block diagram and obtain the transfer function Y (s)/X_(s), assuming that: Rate of oil flow to the piston = K, valve opening Leakage flow across the piston = K, pressure across the piston The compressibility effect is negligible. = = yo Area A L M M 000 ะบ b 1 MUL a Cam Supply y,= KX,
