Can you post a file for us to look at? Otherwise I am just guessing as to what your problem is.
Sorry Ben, I am unable to make the Mastercam file available.

I have tried using all previous operations, also tried selecting one operation and clicking on the stock model. I have also tried defining the stock from an stl file. Nothing works. About the undercut, keep in mind that the view I posted of my stock model is seen from the perspective of Top Plane. When I get to secondary operations, the model and the actual part will be inverted. I have created a Relative Plane for secondary operations and I am attempting to get good toolpath from that position. The undercut is no longer an issue. Thanks for the input.

Hi Ben, thanks for the quick response. Unfortunately, that is not working for me. I have done as you have suggested and yet, I am still getting a lot of unnecessary tool path where the tool is simply cutting air. I can only assume that my toolpath is generating from the original stock definition. that is the only explanation that makes sense.

Ron. I do a fair amount of deep pocket milling like you have described here. We are currently using Data Flute end mills but I am not here to sell you a tool. My recommendation is to slow your spindle speed to roughly half of what you would normally use for this material, and then I would reduce your depth of cut to the least amount that you can take without pissing off every one above you. You will have to find that happy medium between a 84 hour cycle time and crappy finish. PLay around with back plot until you have a depth of cut and a cycle time that you can live with. Long tools don't like high spindle speeds. Let me know how it turns out.

So here's my question; I am programming a relatively simple part on a 5-axis Mikron Mill. I have machined 4 of 5 available sides of the stock to finished features. Now I want to flip the part over and finish the last of the features. I have created a Stock Model from all of the previous Operations, and also created an stl as a back-up to my stock model. I want to generate an Opti-core or possibly an Opti-rest toolpath for Side 2 set up that generates its toolpath from the Stock Model that I created. But Mastercam is not cooperating. It just won't recognize my Stock Model and generates only from the original stock definition. I have already set the Stock definition in Backplot/verify options to the new Stock Model but that seems to have no effect. Does anyone have any suggestions? I have attached an image here to show my Stock Model

Thanks, J. I will give that a try. Update; That didn't work either. I am giving up on this method. I am going to use the process that Guyinthedesert has suggested. 2 ops instead of 1. Thanks to everyone who stepped up to offer help.
