HSM with MasterCam Dynamic Milling has long been one of my favorite toolpath strategies when machining hardened and tough to machine steels.

The job at hand was to machine out a 5" disk out of pre-hardened 4340 steel. About 43RC hard.
Due to an island in the middle (leaving only 3/4" room for the tool) I could not use a bigger indexed cutter, so i decided to use the adaptive clearing toolpath.

I started out by calculating Speeds and Feeds with HSMAdvisor and come up with the following starting parameters:

Full depth, at 10% engagement.

Which worked just fine. But the tool was not new and I decided to sacrifice it in the name of science and maxed it up to see how long the tool was going to handle it.

So I adjusted the cutting speed to 170% and feed to 150% (which accounts to heavy roughing):

To be honest I was not sure the tool was going to last very long, but it exceeded all my expectations!
It lasted for about 2 hours and completed the whole run of more than 20 pieces.

I even took a video cutting one of the parts:

Note how there are no sparks coming out. This is because the chip is thick enough to not overheat. This works both ways. Chips stay cool and due to their larger mass carry most of the heat away from the cutting edge.

After the end of the run (and it was not new to begin with) the tool looked like it could do as much!

This is 21st century and we all live in the age of the Internet.

While some software developers claim to use it for the benefit of the customers they in fact only care about license protection benefits it can provide.

Here is how HSMAdvisor Speed and Feed Calculator uses the big WWW for the benefit of its users:

1. Tool Database and Cutting Data Sharing
   Not many users realise that simply placing the Tool Data Base file on a shared network drive or service like DropBox or Google Drive will keep their Tool DB in sync on all of their computers running HSMAdvisor.
   Oh, regarding the "running on multiple computers" thing.....
2. Floating License allows users to run a single seat of HSMAdvisor on multiple computers non concurrently.
   All you need is internet connection! Permanent Licenses do not even need internet connection at all.
3. Cloud-Hosted Machine Profiles.
   Machine Profiles are important part of out calculator tool. Among other things they allow to prevent machine stalls and resulting machine damage and tool breakage.
   You can upload your Machine Profiles to HSMAdvisor Cloud for Public or Private access.
   Or you can request a machine profile to be added and I will upload it for you to easily download.
   All within the HSMAdvisor Machine Definition dialog!
4. Cut Cloud. The place to get other Machinist's experience at your fingertips.
   Another great feature that we are actively developing right now is the Cut Cloud.
   It allows Machinists to share their cutting experience with other HSMAdvisor users.
   It is still in development but shortly we are going to populate out public online library (Cut Cloud) with cutting data from popular tool manufacturers.
   Anyone running HSMAdvisor will be able to just dial in their cutting tool, connect to the Cloud and see how others run their tools in similar cutting conditions on similar machines.
5. Immediate and Accurate Licensing.
   A few times I got emails from disappointed machinists who were not aware of HSMAdvisor and thus chose a competing software product.
   They all were complaining about misleading Licensing schemes some software developers were using that hindered their work. Things ranged from not being able to register their seats for hours after completing the purchase to having to keep their computers online almost uninterruptedly (despite claims it could run offline for weeks) to keep their software running.
   HSMAdvisor uses transparent Permanent and Floating Licensing scheme that will not leave you hanging.
   All purchases are handled automatically and our new customers do not need to wait for a next business day to get their purchase functioning.
   We constantly work on making your experience as flawless as possible and do not linger on past achievements.

There is a lot more work planned and already in progress.

In the age when everyone is talking about how internet is turning the world around we are doing our small part in making it happen!

Thank you, everybody for your support and feedback!

As unhappy I am to learn that something may be wrong with the software I develop and love, negative feedback is essential in learning whether i am doing everything right.

So a couple of days ago I received an email from a somewhat disappointed user. 

He (lets call him Peter) was complaining that HSMAdvisor calculator gave him "excessively high" speeds and feeds for his 3/4" 4 flute 3.0 LOC  end mill in aluminum.

With the data Peter entered he was getting around 10000 RPM(SFPM 2117) and the feed of 270 inches per minute while usual practice in the shop was side-milling aluminum at that (2.8" axial) depth at only 325 SFM

After double-checking the numbers I replied that in fact his numbers seemed very slow and if for some reason he HAD to run that slow (heck, i machine most steels faster than 325 SFM) due to some conditions, perhaps, he was ought to change the conditions themselves.

This is what I am getting for Peter's end mill setup:
