In this release I have added CAD/CAM integration.

Please read the latest tutorial in HSMAdvisor Tutorials section here
This is a pretty Unique way of doing it.

It is still in the beta-mode.
But it is fully functional. I have tested it on MasterCAM and SurfCAM with great results.
While some functionality is not supported well on all cadcam packages, it is still much better than nothing.

Please send me your feedback on how it works with your CADCAM package.

I have also added a list of recently used materials.

Now material list will have 6 recently used items at the very top of it.
Later on i will allow user to enter whatever number of recent items he wants to see there. But for now its just 6.

New Computer ID and New License keys

Starting from this release i have changed how Computer ID keys are generated.
This was done to fix problems some of the users experienced when they added or removed additional hardware on their computers.

New Computer ID's mean License keys have been changed for all users as well.
Not to worry though, License keys will be automatically updated for all of our users, so no action from their side is required.

If you have active license. You will get a message telling you what happened and your license file will be updated automatically.

Some bugs got fixed as well.

All of them were pretty minor, nothing to write home about.

Material definitions got updated as well.

Added several materials, updated speeds and feeds for tool steels and stainless steels.

I still have to add some of the previously requested materials (like Weldox Graphite, etc) to the list.
And i am planning to add it in the next release.

Chiploads for micro-milling were changed as well.

Chiploads for micro-endmills (below 1/16 dia) were reduced significantly.

NOTE. THIS INTEGRATION MECHANISM HAS BEEN DEPRECIATED AND REMOVED FROM HSMADVISOR.

One of the most requested features in HSMAdvisor has long been integration with various CAD/CAM solutions available on the market.

There are two possible ways of achieving said task.

First way: using CAD/CAM API to create plugins to enable HSMAdvisor to "talk to" various software packages.
This road could produce the best results, however implementing it would be laborous and results not always very convinient to use.
Also developer(me) would have to create plugins for many dozens of cad/cam software packages. Muliply that by the fact that with each CADCAM release, a new version of plugin would need to be produced, tested and debugged. This work is for a whole software department and would call for a product far more expensive than what a lot of my customers could afford.

Second way: Grab tool, speed and feed data directly from the CAD/CAM window, process it and then update required information when the calculation is done.
This solution is easyer to implement and could prove to be the most convinient for user as well.

Need i tell you that i have chosen to go the easy way?

Without further delay let me introduce the first Speed and Feed calculator that can be integrated with a CAD/CAM solution by a user himself!

This is How it Works

Step One: User launches CAD/CAM solution. We will use MasterCAM x2 in our case.

A toolpath is programmed the usual way, a proper tool is selected and when it is time to enter your speed and feed data you launch HSMAdvisor.

On FSWizard page you first select Read More 

HEM is a relatively new term.

It means High Efficiency Milling. It only became available when constant tool engagement toolpahs became almost standard on most of the CAM software.

Unlike HSM that utilizes chip thinning effect, HEM relies on much larger widths of cut and thus chip thinning does not occur. What gives it its name is much higher material removal rate that would normally be possible.

When you are machining a pocket you are most often only milling at about 50% WOC. But nevertheless you need to calculate speeds and feeds based on the fact that the very first move and every corner will be full slotting action. Which means that the whole pocket needs to be machined at lower feedrate.

HEM uses constant engagement toolpths to make sure that this never happens and that Width of Cut remains optimal. Tool never needs to make a full slot so you can ramp up the feedrate as if you were doing outside profiling.

Here is a video of a 1/2" 3 flute endmill machining a 5/8" deep pocket in aluminum at full depth. Normally this pocket would have been machined in 2 steps at 150 inches per minute.

Using Constant Tool Engagement toolpaths we can go full depth at 0.175" stepover and 275 inches per minute.

The advantage of this method is obvious- Higher Productivity.

HEM is not ideal for all cases and each application merits its own method of machining, but its always nice to know more than one way to do your job.

I have been asked to create a tutorial on how to work with the tool library, so here it is.

myCut Tool Database is quite a unique thing.

It not only contains all of your tools, but also each and every tool can have multiple operations or "Cuts" attached to it.

Everything is very simple.

Database contains Libraries

Libraries contain Tools

And Tools contain Cuts

Each entity behaves according to specific rules and "knows" specific kind of data.

I have just uploaded a new release of HSMAdvisor.

I have decided to extend trials every time major releases come out.

This will happen every several months or so.

This release is pretty big. So every one who has not purchased yet gets 30 days more to play with it.

We have material cross-reference tool.

It allows you to quickly figure out material group for a large number of materials. Around 1000 of them.
You can access it by pressing "MORE" button next to material drop-down list.

Here is it looks:

Second Big thing is new tool life estimator.

It allows to show you how tool life reacts to changes in speed, feed rate and depth of cut.

It is a percentage based on normal shoulder milling cut that should equal 100%

Nobody else has this feature- it is absolutely unique to HSMAdvisor and that is in part why i decided to extend trials this time.

Besides tool life gage there is a new tab in results area.

It is called Gages.

It shows important information like what percentage of deflection, torque and machine load we are running at the moment.

It helps to figure out at a glance if something is out of whack.

As always feedback is welcome.

If you are working in mold-making, prototyping or even in a job shop you have had to use unusual form tooling before in your life.

Form tooling is often used to machine undercuts and other features on regular 3 axis machines that would otherwise require a multi axis machining centre or are not machinable o at all.

The classical example of a form tool is a tear-drop ball mil, also known as a "lollipop". It has a tip with a certain diameter and a much smaller shank that produces enough clearance to machine undercuts on straight walls. It can also be used to regular surface finishing and 2d milling.

Another example is a T-slot cutter that is used to produce key-ways and t- slots

The main thing to consider when machining with reduced shank end mils is deflection and torque.

While deflection is especially dangerous for long tools, torque becomes much more important for tools with severely reduced shank.

Torque required to break a tool is directly proportional to the diameter of its shank.

And when shank diameter is much smaller than the tip diameter it does not matter how short that weak portion is: unless you compensate for it you will snap the tool.

The first thing that crosses the mind in many such cases is "I gotta run this tool very slow". It may take forever, but in many cases job gets somewhat done.

Contrary to that many experienced machinists have been proponents of different approach. Instead of reducing feed rate to the point of rubbing and below, it is much more productive to reduce cutter engagement if possible and leave feed rate settings largely unchanged.

Trying to keep proper chip load is even more important when machining work-hardenable materials like stainless steel and titanium. In those cases rubbing is not just unproductive, it leads to a very premature, in many cases instantaneous tool failure.

Just how much of a cut is possible to take in each particular case is the black magic that separates beginners from seasoned pros.

Not to worry though

Here is an example Read More 

We all have manufacturer speed & feed charts and have used their recommendations.

But sometimes those charts just don't apply.

For example manufacturer charts assume you are using their endmills at a certain stickout length, flute length and at a certain depth of cut.

But in the real life you rarely match all these conditions.
Sometimes you need to use longer endmill. Sometimes your flute is longer than what manufacturer gave you speeds and feed for.

What i am trying to say is that whenever your real life conditions differ from "normal" you "need to adjust accordingly".
In fact this is what is printed below many charts.

Too bad not many sources tell you how and what to adjust.

While failure to adjust cutting parameters often leads to chatter, poor surface finish and even tool breakage, one of the biggest mistakes people do when machining is Read More

HSM or High Speed Machining is becoming more and more popular each day.
Many of us have seen those youtube videos where endmlls remove large amounts of material at high speeds/feeds.

While definitions of HSM may vary between tool manufacturers and even individual shops, the physics behind it remain the same.

In this article i would like to explore flat endmills.

HSM is not about ramping up your speed/feed overrides to 200% and puling out your smartphone to record another youtube-worth video.

What is HSM?

HSM is a complex of programming, machining and tooling techniques aimed at radical increase of productivity.

Programming

The cornerstone of HSM is low radial and high axial engagement of an endmill with the workpiece.

There are many CAD/CAM systems that allow you to create HSM tool-paths. Mastercam's Dynamic milling and SurfCAM's Truemill are some of them.

When radial cutter engagement with the material is smaller than the radius of the tool an interesting thing happens.
Chip load- the distance the tool advances per cutter revolution per tooth- does not equal the actual chip thickness anymore.
Chip thinning mainly happens at radial engagements below 30% of the diameter.

In order to get compensated chipload you need to multiply recommended by manufacturer chipload by the chip thinning factor.

Usual Radial Engagement for HSM toolpaths however is between 5 and 15%.

Axial depth of cut varies depending on geometry, but Read More
