Sometimes I get asked whether hsmadvisor CNC Machinist Calculator is reliable enough out of the box.

I and many others test it at work every day. This 2"x1.5"x1.25" 4140 PH piece was programmed on masterscam with hsmadvisor speeds and feeds with all overrides set to default.

Worked out fast and awesome. As usual!

I regularly follow practicalmachinist.com forums.
Especially the cnc machining section of it.

I notice when CNC Speeds and Feeds questions come up people often suggest my HSMAdvisor Machinist calculator.
A referral by a satisfied customer is the best referral in my opinion. Thank you to everyone doing this great favor to me and my prospective users!

Other times users of HSMAdvisor question speeds and feeds it generates and instead of going to me, they ask on forums.
Which is always fine, because extremely often "wrong" results mean something wrong in users expectations or the data he feeds the calculator

In the process of discussion it usually turns out that the calculation results were correct, but because user decided to use a depth of cut or tool length, larger than he should have, HSMAdvisor compensates and gives a very conservative feed rate.

Just like in this forum post over here: Engraving with a 1/32 ball mill machinist wanted

Did you know there are three ways you can touch off your tools?

Because of how Machine Offsets add up, there are several ways CNC machinists can set their Tool and Work Offsets.

This is especially true for Tool Length Offsets.

Tool Offsets can be either Positive or Negative.
Depending on your Machine Shop equipment you should use one or the other.

Regardless of how you set your tool length offset, you apply it the same way.
Right after the tool change and after turning on your spindle and moving to your X Y position above the part.
The very first absolute Z movement should be the line where you apply the tool length offset.

Positive Tool Offsets (gage line tool length offsets)

In the case of Positive Tool Offsets, the offset represents the Length of the tool measured as a distance from the Gauge Line of the spindle (typically spindle nose) to the tip of the tool. The longer the tool, the larger your Tool Length offset will be.

Before we run any G-Code program, we need to tell the machine where our part zero is.
A Part Zero is simply a bunch of numbers that offset the axis to give the machine a new coordinate point to work from.

Work Offsets is one of the most basic pieces of knowledge any machinist must-have.

Let us account for all the basic coordinate systems and definitions, available in a generic CNC machine

• Machine Home and (Absolute) Machine Coordinates
• Work Offset Coordinates
• Tool Length Offsets

Machine Home and Machine Coordinates: G53

Machine Coordinates (or Absolute Coordinates) is the absolute and constant representation of the machine axis position.
These coordinates never change between Machine Restarts and must remain such. In fact, there is often no way for an operator to adjust the Absolute Machine Axis Home position.

Machine Home is simply that magical place where all Machine Coordinates should become Zero.

To Home the Machine is to start a machine operation, that will move all Axis to their soft limit position where X, Y, and Z-axis reading will be set to zero.

Homing must be done every time you restart your machine. Without it machine does not know where is the position of its table or spindle.

When homed your machine coordinates will read X=0 Y=0 and Z=0 and it is going to look like this:

The point where Machine X and Y intersect is called Table Home Position and the one where the Machine Z-axis starts from is called Spindle Home.

Now, there is no agreement between machine tool manufacturers on where the machine home should be.

Canned cycles are used every time we need to drill, ream or tap holes on our CNC machine

Standard Fanuc G-Code language supports more than a dozen canned cycles.

The most common cycles that will cover 99.9% of your g-Code CNC programming work are:

Subsequent holes

You can drill additional holes After your canned cycle has been initiated.
Any line with X Y position will be treated as another hole position.

Each position can have its own Retract value, feed rate and retract height modifier.

G80 - Canned Cycle Cancel Code

After all the holes of the canned cycle have been drilled, it is required to call G80 code in order to cancel the current cycle.

It is no secret that i am trying to make my software fit the broadest possible group of people.
And while my much-respected hobby customers is a big deal for me, industrial machining is where HSMAdvisor really shines.

Recently a PracticalMachinist forum member Atomkinder posted a video of him machining something on his 1997 Fadal VMC.
Here is what he had to say:

Advanced CNC Speed And Feed Calculator - HSMAdvisor

I use it daily, and I can't think of a time it's let me down.
I second HSMAdvisor. I own my own seat (work doesn't have one) because I like it that much.

This isn't particularly special, but it is a 1997 Fadal VMC2216 box way machine. Removed a whole tool and something like 40% of the cycle time from the second operation of this part.

And here is the link to the video: https://www.youtube.com/watch?v=vHN5z4EKODQ

40% of the cycle time. Aint bad, is it?

In industrial settings, with such great savings HSMAdvisor may very well pay for itself within a day or less!

I have just uploaded my first FSWizard CNC MAchinists Speed and Feed Calculator video tutorial.

This is a quick walk through the basic functionality when using milling tools.

Please excuse my tired voice and occasional stuttering. This was my 9th take- every time either my computer crashed or i was interrupted by my kids running around and causing mess.

I am planning to release more videos. So please let me know what other topics i need to cover.

I would like to thank everyone who has helped with the development of our software by investing your time and money, making suggestions, reporting bugs, recommending our software on various professional online message boards and to your colleagues.

Every bit of money I charge for our software goes back to development.

Unlike most other software developers, who often hold back on features to not allow their products to compete with each-other, every useful feature available on mobile FSWizard goes to the desktop-based HSMAdvisor and vise-versa. Even if it ends up hurting overall sales.

I was the first developer who was able to bring a speed and feed calculator as complex as FSWizard to the mobile platform and I have just uploaded another update to FSWizard Mobile app, that makes it even more powerful. Almost as powerful in fact as HSMAdvisor.

Why bother? Why create a competing product that does almost as much, but costs almost 3 times cheaper?

Because I know that most of our mobile users are not only unable to buy a more expensive desktop product, but they are also often younger, less experienced and hold machinist positions without access to desktop computers.

These users deserve every help they need to grow skills and their careers.

And when they grow to be CNC Programmers and get to sit in the office, they would need something more convenient and more powerful.

I hope they then remember that the same guy who develops FSWizard:Mobile also develops an even cooler desktop application called HSMAdvisor, that will certainly help keep their bosses even happier than before!

Once again, thank you, guys. Please have a Safe and Prosperous New Year.

Here is the list of recent changes to FWizard:Mobile v1.38

A couple of days ago I helped a gentleman by answering a few questions about using HSMAdvisor Speed and Feed Calculator to machine a 310 Stainless Steel piece using HSM techniques.

Today he created a post on PracticalMachinist forums walking us through his experience.
And he even took a video of the part being cut!

Endorsements like this is the best thing any software developer can hope for.

I always welcome any feedback regarding my software and never mind helping anyone, whether he is a novice, experienced machinist, my customer or not.

Thank you Sebastien, good luck to you!

I sometimes get email letters from beginning CNC machinists thanking me for making the FSWizard Online Speed and Feed Calculator available for free and asking for some tips and hints.

I always answer and try to encourage people.

Looking at my own CNC career I realize that the thing that is making me successful in my eyes is my own laziness.

Because of how lazy I am I always try to make things the fastest and easiest way possible.

At my previous day job I earned several awards for improving various processes many times saving the company thousands of dollars and many man-hours as a result.

So the main advice I have for those willing to advance is "be lazy"

Always try to improve on your work and make things work faster and better, so you do not have to work hard. If you are successful, your boss will notice.

Bill Gates - the founder of Microsoft once said that he would always give the hard jobs to lazy people, because they always manage to find ways to do them easy.
