So what you want to do is the following:
OP1: face and rough turn OD
Flip the part around
OP2: face and rough turn OD then finish profile
You have a couple options:
1. Use two part files, one for standard orientation, one for reverse orientation
2. Use one part file but have two sequences
Using the first option should be pretty straight forward. Output the code for both programs and then use copy/paste to get it into one file.
The second option you will need to create a second CPL on the origin of the back of the part. When you are in the manufacturing side and select "file > new sequence" it will prompt you for the initial CPL, this would be the CPL you had made on the back face.
Make sure that Z is pointing in the correct direction.
Then program it accordingly. You will still have to output two programs and then copy/paste them together.
The convenience of option 2 is that you only have one PPF file and when you simulate it will look correct. For option 1 to simulate correctly you will have to save the stock model as an STL and import it into the second file.
