- One Case of HSM Machining: HSMAdvisor vs. All by email@example.com on May 3
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:

One of HSMAdvisor users asked me for help figuring speeds and feeds for machining stainless on his underpowered Tormach 700.
He volunteered to send me a model to work on, so I decided it was a good opportunity to make a learning video and share it with everybody.
I must say programming for such a low-power machine is a lot harder than for a full-blown production VMC where you are not worried about stalling your machine with anything under 1" in diameter:
Your thoughts and comments are always welcome.
We are actually listening to our users!

I personally use HSMAdvisor at work every day and trust its results 100%
I have to say my program now knows about machining more than i do. I certainly can not remember cutting speeds and feeds, reduction factors, depth of cut and a ton of other information for every material I have ever cut.
Now add to that the various possible combinations of tool/material/coating and it becomes a no brainier, that a good speed and feed calculator like HSMAdvisor saves a ton of time and money by improving your tool life and productivity.
It is not only good for HSM (High Speed Machining) but also for general machining, drilling tapping, you name it.
The algorithms it employs are far superior to what other calculators are using. Take for example the real-time depth of cut/deflection optimization, that other calculators do in a separate window and take a few seconds to complete.
Here is a quick video lesson where i show the steps involved in creating a simple contouring toolpath in MasterCam x9:
And here is the video of machining the actual part:
Proper machining depth and width of cut are just as important as proper Speeds and Feeds.
This is not only importanttant for professional machinists, who are machining on the edge of their tooling and setup capability, but also for hobbyists, who often face limits from the machine rigidity side of the equation.
HSMAdvisor Speed and Feed calculator has a unique tool used for figuring the best engagement values for each particular cut you are making.
It is called Performance Slider. And it adjusts expected load on the tool and machine depending on your preferred machining mode.
Check out this video I made that explains Performance Slider' functionality:
I have just uploaded my first FSWizard CNC MAchinists Speed and Feed Calculator video tutorial.
This is a quick walk through the basic functionality when using milling tools.
Please excuse my tired voice and occasional stuttering. This was my 9th take- every time either my computer crashed or i was interrupted by my kids running around and causing mess.
I am planning to release more videos. So please let me know what other topics i need to cover.
