The main advantage of the meter in circuit is that the cylinder undertakes one side pressure with a valve corresponding to the real load. The relatively small friction due to pressure on one side, decided by the load of the piston sealing ensures it's long life. The uniform motion of the piston rod even at a very slow speed.

6. Limiting and balancing of hydraulic forces are easily performed. 7. Frictional resistance is much less in a hydraulic system as compared to a mechanical movement. 8. Hydraulic elements can be located at any place and controlled reversely. 9. The noise and vibration produced by hydraulic pumps is minimal.

A shaper machine is one of the types of machine tool which uses the relative motion between the workpiece and the cutting tool. With the help of this linear motion, this device machine (cut) in a linear toolpath. Its cut is quite similar to the lathe machine. Lathe gives us a helical cut while the shaper gives us the required linear cut.

Definition. Hydraulic circuits transmit and control power from a mechanical input to a mechanical output by means of liquids, mostly oils. Power is transmitted hydrostatically, where high pressures make static forces dominate over dynamic forces, and energy is transmitted mostly through static pressure at low flow velocities.

platforms and other press machines. High-precision hydraulic synchronization control technology has become the main way to improve lifting synchronization accuracy. Due to the fact that the hydraulic system has a nonlinear, a large time delay, a high inertia characteristic, se of traditional Proportional Integral Derivative (PID) control is
