Am I using HSMA incorrectly?
I've been using HSMA for quite awhile now, and it has been really helpful. However, sometimes I come across numbers that make me wonder if I'm using it wrong. I'm machining some aluminum with a Garr A3 endmill (07027). Admittedly, speeds, feeds, and cutting parameters is an area I struggle with, but HSM is suggesting an 11.8% stepover, which seems very low for aluminum, I'm used to running closer to 30% stepover in aluminum. Is that because of the ADOC and stickout? When I put those same numbers into Garr's Technical Advisor, they recommend almost 3x the chipload. Garr's app doesn't suggest RDOC, so I used the 11.8%. Of course, Helical's app gives wildly different numbers again, when I use an identical Helical endmill. But, I'll just focus on the 2 apps for this question.
