As unhappy I am to learn that something may be wrong with the software I develop and love, negative feedback is essential in learning whether i am doing everything right.

So a couple of days ago I received an email from a somewhat disappointed user. 

He (lets call him Peter) was complaining that HSMAdvisor calculator gave him "excessively high" speeds and feeds for his 3/4" 4 flute 3.0 LOC  end mill in aluminum.

With the data Peter entered he was getting around 10000 RPM(SFPM 2117) and the feed of 270 inches per minute while usual practice in the shop was side-milling aluminum at that (2.8" axial) depth at only 325 SFM

After double-checking the numbers I replied that in fact his numbers seemed very slow and if for some reason he HAD to run that slow (heck, i machine most steels faster than 325 SFM) due to some conditions, perhaps, he was ought to change the conditions themselves.

This is what I am getting for Peter's end mill setup:

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!

Have you ever wondered how much tool life can deteriorate when using coolant with High-Speed Machining (HSM)?
Or maybe you never really saw the boost in tool life when using HSM techniques because you had to use coolant?

Well, here is a test result I just got from running the same tool at the same Speed and Feed with and without coolant.

We all know what the CNC Milling Machine spindle is used for - to hold the tool. But it is old and boring. Everybody does that.

Here are the 6 interesting and maybe less common ways to utilize machine spindle, increase productivity and solve some problems you never thought you had.

Use your Spindle as a fan to blow chips and coolant off of your work-piece, table and fixturing.

I saw this little gadget at a local IMTS show and it was quite cool. It is installed into a tool holder like a regular cutting tool would be and at the end of the program you can call the it up and run a little table-cleaning program to make your work a lot cleaner!

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.

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%!

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:

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!

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.
