Cylinder $1\mathrm{.}0$ extends and clamps the pipe and subuequendly cylinder $2\mathrm{.}0$ retracts. Flanging cylinder $3\mathrm{.}0$ extends for the first lime for the preliminary flanging operations and then retracts, The tool switchover is performed by cylinder $4\mathrm{.}0$ and flanging cylinder $3\mathrm{.}0$ is in action for a second time for the final flanging operation. The complete retraction of cylinder $3\mathrm{.}0$ triggers the return motion of elamping cyfinder $\backslash (1$: $0\backslash )$ and lool swisching cylinder $4\mathrm{.}0$ and forward motion of operations cylinder $2\mathrm{.}0.$ The required sequence of operations is shown in the Figure$-2($b$)$ Displacement$-$step$-$Diagram. Develop a preumatic control circuits to implement the control task by cascade method.
