In the drilling process shown in Figure 1, there are three cylinders in which cylinders A and B are used to clamp the work piece and Drill cylinder is used to lower and raise the drill. The sequence of operation are as follows: 1. Activate the lever of the 4/2 DCV to start the process 2. Cylinder A and Cylinder B clamps the workpiece at the same time 3. Activate the second DCV (4/2 DCV with spring return) to drill cylinder lowers the drill and raises afterwards (use the throttle valve and check valve to control the speed of the drill low). drill up is normal speed. 4. Once the drill is raised completely, operate the lever to retract cylinder A and cylinder B. Note: provide the following clearly 1. List of the components required 2. Hydraulic circuit with description to each component 3. state diagram should present the sequence of operation sensors Drill-high Drill Drill-Low Part / Material Cylinder A Cylinder B B+ sensors Figure 1: Drilling Process a) Design the Hydraulic Circuit with…
