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!

Huge "Farewell to MasterCAM x9" HSMAdvisor Hook update has been released.

The MC 2017 has been out for a few month now and because it has received quite mixed reviews from the machinist's community, i decided to release one more big update to our MCx9 hook before starting to fully work on adapting it for MC 2017.

This update v1.402 is a double update. The hook version has now caught up to the standalone AND we have some new features in standalone HSMAdvisor as well.

Here is a quick video showcasing most of the new features:

What is new and improved in this HSMAdvisor update

• New Hardened D2 and M2 Steels
• New 17-4 and 13-8 Stainless Steels in various conditions
• Mew DB Contents Tree in Select Tool Dialog
• Plunge Speed Lock
• New Free GD&T Reference Tab
• Updated Look and functionality of Scientific Calculator
• Updated look of all Geometry Calculators.

Whats new and improved in HSMAdvisor Hook:

• Improved Toolpath import and export
• New Improved Select Tool/Cut Dialog with Side Contents Tree
• Plunge RPM lock for toolpaths, that do not support Plunge RPM different from the main RPM
• Ability to choose which data is read and written into the toolpath.
• Full ToolDB Functionality including editing and saving tools is now free.

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!

It does not annoy me anymore!

Originally this part was programmed for and machined in 6061 aluminum, but when production run came, material was changed to HRS and then to SPS (4140).

Luckily reprogramming using HSMAdvisor hook for MasterCAM is a bliss.

Mere 5 minutes and all speeds, feeds, depths of cut, etc. were changed to safe and productive values.

New Material

Being a CNC Machinist/Programmer is sometimes more than simply creating a program and machining the actual part, often times it is about creating efficient and accurate fixturing.

In this little project:

I had to machine rectangular cut-outs and drill holes through an already-turned steel ring. Then I had to part each ring to 4 equal pieces.

There were about 100 such rings that worked out to 400 pieces in total.

After drilling holes on an indexer I had to machine a fixture to hold my part through 2 remaining set-ups.

First half of the fixture consists of the expanding mandrel:

The work-piece would be mounted on it like so. A hole on the side is used to properly position it:

Being as vast and as complex as it is HSMAdvisor Tool Database may seem overwhelming for many users despite all the benefits of using it.

To address this issue I have just added a new category to our HSMAdvisor on-line Help resource called Tool Database & Tool Inventory

Here is a the opening article of that category:

In all there are 5 articles in there already describing many of its functions in detail.
Please check them out if you are not sure what the Tool Database does and how to use it.

And as always: when in doubt - ASK :)

HSMAdvisor the Hook for MasterCAM x9 has had massive changes since the last update

• Completely redone Operation Import/Export functionality
• Added "Insert Operation" command (Add it to MasterCam toolbar through Customize->Toolbars->HSMADVISOR->select item,select toolbar-> Add..)
• Reworked MC Toolbar Icons
• Better tool Recognition
• Added support for ALL milling (2d, 3d, HST) operations. 
• Fixed a huge number of problems including those with coolant, tool numbers and some unsupported operations.

HSMAdvisor hook for MasterCAM currently supports only MC x9.

Due to large amount of work I have done on x9 hook I decided to not port it to support x8. I simply have no time resources to do so. I only have one life you know!

Later versions of MasterCAM will, however, be fully supported.

Every month we are getting a good amount of feedback and suggestions.

Everything is getting prioritized and eventually implemented. Urgent stuff is getting done fast. And other "nice to haves" are getting pushed down according to their usefulness / difficulty (yes, everyone secretly wishes my program could also edit and create HSM g-code :)).

It is amazing, but almost half of HSMAdvisor's features were originally suggested by our loyal users!

The latest update HSMAdvisor 1.213 addresses some of the feedback I have received last couple of months.

So the New features are:

1. Smart Depth and Width of Cut (DOC/WOC) suggestion (user suggested)
2. Compressing of Shared Tool DataBases
3. Display of Stock status on Tool DataBase tables (user suggested)
4. Various little improvements like new Heli-Coil reference, better DOC/WOC calculation better multitasking, etc. (mostly based on user feedback)

Let's go over the most important ones here:

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:

I had some unfortunate troubles initially releasing the mastercam hook this month.

But thanks to the feedback from my users and the fine folk from eMasterCAM.com community they are now over!
