Design the hydraulic circuit for clamping and drilling operation shown in Figure 1. with the following requirements 1. In a workshop, drilling operation is performed using a hydraulic system. 2. Cylinder B is used for clamping, Cylinder A is used for vertical displacement and a hydraulic motor is used for drilling. 3. The work piece has to be clamped using Cylinder B and it should be extended in such a way that it should not damage the workpiece. Therefore, use proper valves to control the speed of the extension. The return stroke can be faster than the extension. 4. Then, Cylinder A can be operated verticall to perform the drilling operation. use proper control valves to control the speed of the extension. 5. The hydraulic motors can be operated parallelly with Cylinder A, but the extension speed of Cylinder A should not affect the speed of the motor. NOTE: use only TWO Directional Control Valves

For the pneumatic circuit in the figure, name each of the components and describe their operation (what each action does).
Design the electro -hydraulic circuit for the lifting and shifting operation as shown in Figure 2 with the following requirements. Following are the sequence of operation. Products are required to be transferred from lower level conveyor to higher level conveyor using two hydraulic Cylinders (Cylinder A and Cylinder B) and a conveyor belt (semi rotary motor) Cylinder A lifts the product on receiving it at lower level to the platform. Then, Cylinder B shifts the product from the platform to the conveyor, Then the conveyor motor should be rotated after 5 seconds to transfer the product to packaging Repeat the sequence of operation for 10 trials. NOTE: use independent DCV for each actuators (Cylinder A, Cylinder B and Conveyor motor)
