Please first make the CAD model from original block size $({50\mathrm{.}0}^{\text{@}\text{'}}{18\mathrm{.}0}^{\text{'}\text{'}}{12\mathrm{.}0}^{\text{'}\text{'}})$ and then design CAM process to manufacture the top profiled surface of this mechanical component using surface milling. After completion, please convert the CAM simulation video $($showing the manufacturing process$)$ to the MP$4$ format and upload it to the Canvas $(100$ points$).$

Please use Creo CAD. Please explain all steps.
