I was wondering if there is a way to clear a block away avoiding an island where the tool cuts from the outside of the block toward the island?
For instance say I have a 12"x6" block with an irregular island in the center of the block. I want to get rid of everything except the irregular island. I'm trying to avoid having the endmill doing a full slot width cut. The only way I have been able to do this is to increase the XY finish and then decrease it each time until I get to the final dimension of my irregular part. Doing this though has a lot of wasted travel not cutting anything. Any suggestions?
