The Pictorial diagram below shows the system of a hydraulic bending machine used in a production line . A - It is required to bend the material ( blank ) in an angular form by using the Pneumatic system shown below. Draw the appropriate schematic symbolic diagram to make your system work at best. Label all your components. B- In a table, list the names of components used in your layout by referring to their label in the layout . C – Make a technical report describing how your system work and why you have selected your specific components.

Summarise and discuss the general strategies to select CAD/CAM software and tools for Computer Aided Process Planning (CAPP) and optimisation of design and manufacturing operations, especially to generate optimal CNC machining toolpaths, simulate the generated CNC machining toolpaths, create G-Code programs for CNC machining operations, simulate and optimise the Additive Manufacturing & 3D Printing (AM-3DP) processes (Topology optimisation, Simulations of support generation, Simulations of deformation and shrinkages, Simulations of Nesting operation, Optimisations of part orientations).
