Your problem is that the search the way your currently doing is that the search always starts at the beginning of the program no matter where the search is called from. The only way to speed the search is to search for subprograms. There are a lot fewer O numbers to search for than line numbers. If your reason is having to individually delete the subprograms due to wanting to keep certain programs in memory then you should make those programs O8xxx or O9xxx and lock those programs using your machine parameters. You can then delete all the part programs in one process without deleting the programs you want to keep in memory.

No need for the lines, that was an odd shaped feature I cannot show and I made new surfaces to drive the toolpath and that is what you see. Problem I was having was the notch in the top surface and the edges feathering in to half edges along most of the radius on the edge. This is where I break out my modeling methods and make something to drive the toolpath exactly like I want. The issue was Morph was not having it originally or Parallel so I switched to swarf, but really didn't need one way cuts for this finishing operation since I am using a ball endmill. I had used this method in the past, but forgot all about it and then it dawned on me where the switch was. I thought it was worth sharing so here we are.

Read up a little bit on this variable. The max allowable value is 64000. I tried to run it with a value of 40 000, but it had detrimental effect on MC . The opening of the chaining menu slows down among other negative stuff. Also Mcam would suddenly crash even if nothing was being done on the screen. So 20000 it is for now.... Gracjan

Got it. Again thank you guys

Do this: Your not using the Accel and Deccel settings to control the movements when roughing. You cannot bank a car and 1000mph and it is not different for a machine tool. They will try, but they loose accuracy when doing so just the Physics of things. I don't have my CAMPLETE to open it up, but reach out to them they are great and can help you tweak your CAMPLETE to avoid these types of issues.
