Hi Eldar,
We have to machine 4340 but hardened to 42Rc. How should i alter the parameters recieved from hsm advisor? Is there any general formula?

Hi,
Sorry for delay. Somehow totally missed the email notificatuion.
For specific hardened steels, that are not in the list, i suggest using a H13 hardened steel material type with comparable hardness.
Regards.

The unit power that HSMAdivsor uses for endmilling 6061 T6 aluminum is about twice that used by both the Kennametalhttps://www.kennametal.com/en/resources/engineering-calculators/end-milling-calculators/force-torque-and-power.html and GWizard calcultors. Why?

Hi,
I fail to see where on that page kennametal is suggesting the power unit for anuminum?
Any way based on my own testing and the documentation avaialble (most sources recomment Pc at about 0.3 for aluminum alloys) i conclude that power requirements suggested by HSMAdvisor are in fact correct.
See the screenshots.
So until i see any evidence to the contrary, it is not going to change:)
Can not speak for Gwizard.
Edit: just found that thses forums are throwing error after posting a comment... fixed!
Edit Edit: Nex time please create a new thread: we do not want to spam the original poser with automated messages that do not relate to his original question.

Sorry for posting here - it seemed like the most appropriate place since I couldn't figure out how to create a new thread. How do I do that?

As shown below, HSMAdvisor predicts more than twice as much power is required to endmill slots in 6061 T6 aluminum under identicfal conditions.

On top of each forum there is an "add article" button.
But I do not know where kennametal got their numbers. Is it the machinability rating they use?
I guess you would need to ask Kennametal about that. I showed you my sources:)
Cheers!

Kennametal uses 0.29 HP/(cuin/min) for 2024 Aluminum and 0.2 HP/(cuin/min) for 6061 T6. HSMAdvisor uses 0.29 HP/(cu.in.)/min. in the turning calculator and 0.44 HP/(cu.in./min) in the endmilling calculator!

Hi,
After some research modifications were made to the engine that calculates power AND Aluminum materials got power requirements reduced. So in total Aluminums lost about a third of the Pk value.
Please download and install the update.
Thank you very much for your feedback and patience!
