Key factors Determining Success of High Speed Machining (HSM)
As a developer of a very successful line of speed and feed calculators I sometimes get questions like : "I calculated speeds and feeds for a conventional toolpath. Got 5.5 cubic inches MRR(Material Removal Rate). And then I calculated S&F for the same endmill with HSM parameters turned on and got almost the same amount of MRR! What is even the point in using HSM parameters?" -they ask.
I would like to clear some things up for my friends.
In this article I will explain exactly WHY HSM machining is better and HOW to achieve better productivity and tool life.
For starters here are the main features of a HSM-capable cutter:
As usual there are several components of HSM that need to be present in order for it to work to its fullest. These are:
a) Machine
b) Tool
c) Workpiece geometry
d) Workpiece material
I intentionally did not number these as each one of those is equally important.

First FSWizard video!
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.
HSMAdvisor Status Update
First of all Merry Christmas and a Happy New Year !
There has been a spur in development in the last couple of weeks.
Mainly due to the fact that i took a vacation from my day job.
I also used this time to pay a visit to some businesses operating in the area to get some feedback on my software, hear out their needs and desires.
I have not been able to post about the latest updates, so let's summarize what we have at this moment in the latest v1.110 update
- New 90 Degree metric Flat Head screw reference tool
- Ability to use comma sign instead of dot as a decimal point.
HSMAdvisor will still convert comma to dot, but now it treats input properly
This was done to accommodate users whose language settings use comma on their numpad - Fixed scaling for all DPI types.
- Added a bunch of materials like Machinable Wax, Plywood, some Steels etc.
- Improved and made more predictable loading of tools and cuts from the database
- Made improvements to Machine definition window.
Most of the work has been finished on the CAM integration feature.
If any of you, my users, feel like you want the FREE integration with their favorite CAM, please nag your CAM support and/or sales desk!!
........
........
Now did I mention I plan on NOT changing a dime for the integration feature?
If not, then let me repeat it again.
CAM Integration feature will come at no price for my users!
So if i were you, i would file support tickets (make some phone calls, write letters) to your CAM providers and ask them to consider enabling their software to speak with mine.
My contact details can be found here: http://hsmadvisor.com/index.php?page=help&shell_id=241&article_id=4426
Have a nice New Year!

HSMAdvisor v0.950
I have just uploaded the latest version of HSMAdvisor
In this one I made some changes (again) to the layout of the FSWizard tab.
Changes were made according to Your feedback, so i hope you guys like it!
As you can see from the screen shot above Tool Type selection drop-down lists have been moved to the Tool Data panel.
This was made to make it more obvious which values get saved and loaded when user does operations with saved tools.
For the same purpose Saved Cut drop-down is now located on top of all cut parameters that it affects.
The top-most panel (Workpiece) now contains Machine and Tool Library drop-down lists.
I urge everybody to download this update as it fixes all of the existing issues regarding layout changes.
Also in the previous version, when Trial version gets expired, the Splash Screen blocks the License Activation dialog, which would make it impossible to purchase a license or enter your license information.
This glitch and many others have been fixed and i would like to ask everybody to download the latest release as soon as possible!
Cheers!
HSMAdvisor v0.900
New version 0.900 includes one big improvement:
A new "Load Tool" button was added on the Toll Data panel.
When you click on that button, a brand-new "Select Tool/Cut" dialog box appears.
Using this dialog box you can quickly find and load any Tool/Cut from your Tool Database:
When you click on the "Toll Library" header, panel expands allowing user to filter out the tools and cuts that he wishes to see.
Also Expand All checkbox allows to expand all tools on the table.
In the future updates i am planning to completely replace the functionality of the two separate Tool and Cut Drop-Down lists with this single dialog window.
If you have any feedback, positive or negative or any ideas, please let me know!
Cheers!
