Here is another video showing the Haas and Makino during the 2D HST toolpaths (2D core roughing and peel mill). Same part in both machines and same program, for the most part. Haas will not feed any faster than 500 ipm so I had to drop the cutting and return feed rates accordingly. I also ran into some pretty good chatter in the Haas and had to slow things down further. Ultimately things quieted down around 250 ipm but I didn't get any footage of the machine actually cutting chips at that rate. Any faster and I was running into chatter. The cutter was an MA Ford 134 series end mill @1/2" diameter. This is a roughing specific cutter and it does a great job of getting the material off quickly. The 1/4" end mill was an MA Ford 138 series finisher and I really like those as well. So take it for what it is. I'm sure some will love it, some will find it very interesting, and some will think it is unfair and that I am an @ss. I will not be posting any more videos for a while because I don't want to clog up the forum with this and I don't want to beat a dead horse. Lastly, the Makino rang in at 10:57, the Haas rang in at 16:37 running 10" above the part cutting air at 500 ipm, and the Haas rang in at ~18:00 with the core roughing turned down to 250 ipm. Again, the radial step over was 25% with a 5/8 depth cut for the 1/2" tool and .59" depth cut for the 1/4" tool. I would also like to add that both machines were in standard mode, meaning that the Makino was running in M250 and the Haas was running in G187 P2. The Hass will run faster in G187 P1 but it gives up the farm in accuracy. In a core roughing application I would need to leave at least .020" to avoid clipping corners on the finished part and since I am typically finishing with small tools (1/16 ball mill, etc...) I prefer to rough in standard mode and leave .005" for finishing. The Makino could have been run in M251 (performance mode) but with removal rates that fast I am fine with roughing in M250. I can leave .005", do a quick rest rough, and be ready to finish. This is a pretty utilitarian part so it really wouldn't have mattered but I wanted to keep it representative of how I like to program.

i am a new mastercam programmer. what is the difference between 2d area mill and 2d dynamic area mill. like core ,area ,rest and dynamic core,dynamic area and dynamic rest. i know i use full length tool cutter for dyanamic area but i did not understand how it work 2d area mill than 2d dynamic area mill
