We all have heard hundreds of times that when chatter is happening during machining, we should reduce our feed rate. The same advice we also hear for compensating for extra-long tools and unstable setups.

Let me explain why I think this is mostly incorrect.

Let’s list  the effects of reducing the feed rate:

1. Reduces tool life.
2. Reduces productivity.
3. Increases deflection.
4. Causes chatter.

Let me explain from my own experience and research I have made each of these points and a simple way to avoid chatter's adverse effects.Read More 

Latest advances in tool technology make milling of high carbon and tool steels as reliable and predictable as benign aluminium alloys.

In this video a large 4140 steel component is being roughed out at 2700RPM and 600 inches per minute.
While achieving  impressive material removal rate (20 pounds of steel machined off in a matter of half an hour!) the tool life puts the old school square shoulder endmills to shame.

Yes, it could(and should) have been machined using a bigger cutter, but I wanted to put the tool to the test.
And it performed beautifully: Was able to surpass the recommended starting speeds and feeds by at least 170%!Read More 

Look for the HSM machining of the round central pocket in the beginning.
Here we have a 12mm 6 flute Coated hi-performance endmill, cutting 1" deep at 0.047" (10%) rWOC.
at 10000 RPM and 300 ipm feedrate. the chipload works out to be 0.005". Material is 4140 pre-hardened steel.

Impressive isn't it?
Those results have been achieved with uber-expensive BlueSwarf tap-test technology.

This is one video that caught the eye of one of my HSMAdvisor trial users:

Being a geek and wanting to help the user make the right decision I immediately punched the numbers into my HSMAdvisor app.

Here is what I've got:Read More 

I would like to announce the launch of a brand new product called HSMCode.

HSMCode combines the power HSMAdvisor speed and Feed calculator, its advanced Tool and Cut Database and the new functionality of HSMCode into one seamless product!

What does HSMCode Do?

HSMCode allows you to create ToolPaths from imported CAD or Solid geometry with ease.

All you need to do is pick features that need to be machined and HSMAdvisor will pick the most suitable tool, calculate proper speeds and feeds and then HSMCode will generate the G-Code for your machine

As simple as that.

You can also create additional geometry using an in-built CAD designer and Simulate your Toolpaths to verify the correctness of your work.

The sales will begin in a couple of months on June 31 2016!

Please contact me if you would like to test the early demo version, affect the development of the software and (depending on the value of your input) receive your Lifetime Subscription for free!

Cheers!

Don't you hate when "that guy" cuts your stock a little too short?

Holding on to just 0.060" here. The part is 1.5" tall made out of 4140, which helps it stay in place and not collapse under machining pressure. Pretty sure it would have moved if it was made out of mild steel.

PS. Did I eay I love those CR vise? I do. Can't lift that jaw with a lift truck.

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 a professional CNC Machinist myself with a good manual background I often find myself watching various machining videos and blogs.

Unlike others I do not often share somebody-else's work, I could just not walk past this one and not tell everybody how great I think this is....

This story was posted on "Russian reddit" and here is the direct translation of the author's post:

Lets begin with tyres. Vladimir (guy's name) decided to create the mould to make the rubber tyres himself. Here it is:

Here are the tyres he made with it. Beautiful aren't they?

He also made little differentials. Housings, gears. Everything made himself:

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:

There has been changes to HSMAdvisor CNC Machinist Speed and Feed Calculator Licensing Options!

From now on All new HSMAdvisor license purchases include access to FSWizard PRO for your mobile devices.

When a 1 or 3 year HSMA Subscription License is purchased, the FSWizard License will be issued for the same 1 or 3 year length of time.

When a Permanent HSMA license is purchased, your FSWizard PRO will be a permanent type as well and will never expire.

Happy Upcoming Holidays!!!!

Cheers from the whole Zero-Divide Family!
