I have uploaded the latest version of HSMAdvisor today.

It is a minor update that adds in-app registration for existing users with unused seats.

Also have just completed MasterCAM x2 integration profile for the Capture Wizard.

I did not have time to include it into this update yet, but you can download it below.

MasterCAM Mill X2 MR2 SP1 English.xml

This update is mainly a bug fix and has some usability improvements.

New Things

• Persistence in Threads Tab
  Now Threads Page will stay the way you left it when you shut down the program
• Persistence in column selection for Drill Chart for both the Treads Page and Tap Tool on FSWizard Page as well.
• Capture Wizard can now capture target windows with dynamic controls. (Still working on SprutCAM integration profile that required this feature)

Fixed and Improved things

• Tapping tools had a bug in metric mode. Now it is fixed
• Text color for selected row in myCut Database page is now white on blue background. Which makes things easier to see.
• Capture Wizard is now a lot faster and should be less prone to hang ups.
• Improved Machine Limits behavior
  Power Overload now causes feedrate to reduce.

Up here in Canada we are celebrating family day today!

I wish you all more time to spend with your loved ones.

Because of that and just "because" all HSMAdvisor licenses are on hefty 30% sale.

Get your work done faster and go home to your wife and kids!

Version v0.735 has just been released.

We now have 2 new tool types: Counterbore and Chamfer Mill.
They were added to match with similar tools in most CAM packages

Also we now have tool simulation graphics in the Results' area new Tool tab.

Here is a simulation of the new Chamfer Tool type:

Capture Wizard now has Tab Name field that allows Wizard to only capture the Target window when selcted tab is active.

Also Detault Tool Type, Tool Material and Tool coating fields were added.
you can now specify which tool will be picked if Wizard fails to recognise the tool type.

Oh pardon me!

Forgot to mention: We now have Surfcam 5.2, BobCAD-CAM v25 and v26 integration profiles.
you can load those from Profile manager tab on Capture Wizard form.

On a side note somebody from SprutCAM has asked me to create a profile for their package.
Looke like they have demo available for download, so i will probably do that very soon.
As far as I know, I do not really have any customers using that CAM.

But hey, Things change!

Manufacturing seems to be going back to North America, but thousands of college graduates who finish various CNC -related courses have a very shallow understanding of metal-cutting processes and forces involved.

Frankly i believe Speeds and Feeds should be a separate subject all together.

To help students fill the gap, I am offering US and Canadian educational facilities help with setting up their classes with free HSMAdvisor seats.

Update: Countries of EU and England are now included into the offer!

The total maximum number of seats handed out will be limited to 200.

If you represent a college or a university and want to sign up, please send me an email with your name, position, and number of seats requested.

My email address is cnc@zero-divide.net

I will set up your license and reply with information on how to obtain the license keys.

If you know a place that could benefit from this offer, please share this message.

HSMAdvisor has got a brand new CAD/CAM integration profiles manager.

It is now possible to import/export profiles to and from HSMAdvisor.

For now i only had time to add SurfCAM 5.2 to the list. MasterCAM x2 is coming a little later.

While using Capture Wizard yields very satisfactory results in most cases, it does not take a long time to set up either.
The whole procedure of creating a brand new profile takes just about 30 minutes.

If you created your own profile for a CAM system that is not already in the lest, please send it to my e-mail address: cnc@zero-divide.net or create a thread on the support forums. There you can upload XML files directly.

I would like to add it to the next release for everyone to enjoy.

Very good things happen to those who contribute!

If you need any help figuring out CAD/CAM integration. please refer to "HSMAdvisor Tutorials" category of this site, create a thread on support forums, or send me an email!

In this tutorial we are going to explore different options and techniques when programming cutter movement.

Lets begin with a simple part shown in a drawing below.

Basically it is a rectangular piece 4.00x2.00
For the purpose of simplicity lets make the depth of our profile (z- dimention) 0.75"

We are going to use a 0.5" dia endmill, again because it is a very common size and is easy to do basic math with.

I took a liberty of puting locations for our part/toolpath, so it is easy to extract numbers from the drawing just by looking at it.

Notice the green rectangle. This rectangle represents the path that the center of the tool will have to take to produce the part with required dimentions.
The thing is: because endmills have certain diameter, the center of the tool must be always offset by its radius.

There are two ways of doing that.Read More 

At my day job I am starting to do more and more manual programming.

Which i do not realy like, but since am at it anyway i have decided to keep piling little articles about G-Code programming into this new category.
This way when i forget things again i will be able to quicly refresh my memory.

We all love getting positive feedback on anything we do.

For example hearing "good job" from our bosses. Or "nice work" from our co-workers....
Okay, Okay bosses do not normally tell anyone "good job", but anyway that would be nice!

I also like reading e-mails which people all over the world send thanking me for my work on FSWizard and HSMAdvisor calculators.
Telling their success stories and suggesting new features.

Most seem very surprised when they send a question on weekend and receive an answer withing a couple of hours.

Often people send pictures of their work and links to their own web sites.

It is nice that more and more professional machinists are using my software, but seeing it help create a work of art is a special feeling.

One of recent customers Daniel Gentile, uses HSMAdvisor to calculate cutting parameters for his custom knife production business.

Here is what he has to say:

HSMAdvisor enables me to efficiently do the math that saves me not just a lot of time as I can confidently often use higher speeds but also a lot of money, as I tend to break less of those expensive 2 and 3mm carbide tools that see a lot of use on my folder production. Also because I work with a dozen different materials - from D2 steel to Titanium to Bronze - and a lot of different cutter types and finish requirements it's just nice not to have to work with "guess-work" for the feeds and speeds.

Another week another update!

A few days ago a topic popped up in CNCZone's BobCad-CAM forums regarding why speeds and feeds in above mentioned BobCAM were so crazy and unworkable.

Users were complaining and raving about such a "simple" thing like a good speed/feed calculator being missing from there.

This is actually a trend in pretty much any other CAM software package.

They sell tool to create toolpaths.
Many give tools to create 2D geometry and even real solids.

But very few CAM packages offer anything that even remotely resembles working starting cutting parameters.

It does seem bizarre and strange. But every CAM program "knows" type of material being worked on. It knows type of tool, its diameter and length.
It even knows flute length, cutting depth, width, ramp angle... pretty much everything.

But given all that they are unable to combine all this data and produce Speed and Feed that would not either break the cutter or melt it into the work-piece!

Anyway. Back to the topic.

Someone on that forum thread mentioned my old FSWizard.
It sparked quite a lot of interest, and i popped in and dropped a link to the latest version of HSMAdvisor, so that they actually try and see what a good calc can do.

As a result i have received a ton of emails filled with suggestions and thank-yous.

Apparently many did not even know anything about it and were surprised how well it worked for them.
One guy who just bought a license even said that his copy already paid for itself several times over within the first couple of days of using it!

To thank for enthusiasm, i quickly implemented some of those suggestions and i am now releasing them in this version 0.710

New thing are

• Adjustable font size and style. (in Settings) Allows to adjust global application font.
• Adjustable default values for Speed&Feed Overrides, Tool Productivity, Deflection and Torque Limits. (in Settings) You can now set values to which overrides reset by default.
• New Plunge Feedrate field shows up for milling tools.
  Non-Center cutting tools like Indexed endmills etc. will have plunge feed equal Zero.

Thanks everybody for support and suggestions!

As usual you can download the latest release on the Download page.
