Well it is not really a secret for those of us who use it but for everyone else I am sure there is a lot they don’t know. In my last post I talked about the idea of software quality control. In that train of thought there were some pretty amazing results achieved by Helical in testing with HSM’s Adaptive that was something I could not talk about until today. But there are a number of things that go on under the radar with Autodesk HSM (A-HSM) that are parts of an ongoing quest to improve the program. To make sure that what is there works and then also steadily improves.
First though a bit of background for HSM Adaptive from my experience. Roughly three years ago I tried both CAMWorks and HSMWorks. Cutting “Jaws of Life” blades out of S-7 tool steel was the test at that time and Volumill in CAMWorks cut a more consistent chip load especially around the pivot hole where HSM spiked pretty badly in tool load. HSM was good but Volumill was a bit better. Fast forward to today when I was forced to look past Volumill due to Geometric’s failure with Camworks for Solid Edge and it is a different story. On same parts and work holding and cutters today I find that not only does HSM Adaptive find all levels better it almost always does so with quicker cut times when compared to Volumill and with chip loads at least as good at worst and better in most cases.
Today over at a post on Helical end mills http://camforum.autodesk.com/index.php?topic=6490.0 some interesting things come out. Volumill has used Helical as their benchmark endmills for the Milling Advisor speeds and feeds calculator available on their site. Keep this in mind as we delve into this thread. http://www.1helical.com/index.php/latest-news/8-latest-news/51-helical-autodesk will take you to the post referenced there and I want you to go there now and check it out. Especially the recorded speeds and feeds.
Using the Volumill Milling Advisor the closest I can come to the testing at Pier 9 was this. Don’t take my word for this download it and see for yourself!
I have not achieved this kind of dramatic end mill engagement improvement over Volumill in my shop but then I would never have tried something like this to begin with. My biggest improvements have been in the total number of inches of travel to cut a part. Since I use the Volumill derived Machining Advisor to guide me on speeds and feeds who would have guessed HSM Adaptive had such potential?
Judging by this comment from Helical in the Autodesk CAM forum post—
“Again, we achieved some impressive cutting parameters with Autodesk’s adaptive toolpath strategy conducted at Pier 9 and now are in the process of training our tool application engineering staff so that we can help mutual Autodesk/Helical Solutions customers at anytime. I must say that their pier 9 facility was very impressive and we anticipate more great advancements with Autodesk & Helical Solutions in the near future!”
I would have to say it was an eye opener for them too.
Movin on over Volumill, the big dawgs coming in!
