I started to using 2017 today. We do a lot of roughing of surfaces with Sandvik 210 cutter. In X9 you had to describe this tool as a custom tool in 17 it has a new high feed cutter option. I open a part that I just made last week using the 210 cutter as a custom tool. I changed stock to leave on drive and regenerated the tool path it took 2m:24s. Then I made a new tool using the new high feed description I changed to the new high feed tool and regenerated the tool path it took 5m:30s. When I run the verify it looks like the system is recognizing the new high feed cutter better than my custom tool but it has doubled the regeneration time. Any thoughts?
