Alright ! To create a presentation select machine simulation then go to file tab select create a presentation it will create a file for you in order to view the file you need solidcam installed

About the first operation I created a configuration which hides the cut-sweep2 and the curve pattern1 this way you could easily select the surface . The operation is parallel to curves . I hope you know how to select the geometry for this operation. In tool axis control / click on the rotary axis and select point tool to rotary axis this way the tool will stand straight and use roughing passes if you actually gonna machine the part

For second operation change the configuration to default now you have your cuts visible . The operation is morph between two boundary curves and I choose a lollipop mill for this coz the cut seems inward which can't reach with a regular ball endmill . Hope you got the idea
Cheers
