Toolpath Editing for Surface Rough

[bgott]

I am having an issue shortening a toolpath generated by this function. Basically, I have already roughed out the structure of a pocket with a 1" endmill and now I am just trying to go around islands that are in the pocket with a smaller .456" ball endmill for surface finish purposes (this is a plastic injection mold). I am self taught with MasterCAM and I found the toolpath editor but the issue I have is when I delete the toolpaths that take the floor of the pocket down another level it seems to delete the rapids needed to avoid collision. I haven't run the program yet, but the verify simulator indicates that it will crash. 

 

Is there a way to do this so I can avoid having my tool cut air for so long? 

 

Any help is appreciated.

Are you programming with Mill or with Router?  Which product level?

 

If your product has it, you might try using the Surface High Speed Area Rough toolpath referencing a Stock Model of the results of the first toolpath.

I am using MasterCAM X4 mill level 3 I believe. And I will check to see if it has the function you suggested. Ill get back to you about it. Thanks.

Using surface high speed waterline this appears to have worked as far as the verification in program goes anyway. Thanks much for your assistance.
