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!

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.

Recently I had to machine a few pieces after turning.

Because the very top of the part was supposed to be machined off, I could not clamp through the central hole like I often do.

Decided to quickly turn an expandable washer out of aluminum and a plastic spacer that would collapse a little bit under clamping pressure and allow the part to sit firmly against the base of the fixture.

I liked this method so much I am going to do the same next time I have similar part to make.

See pics below.

Later on i will try to post some more pictures of other setups I did.

All the pieces apart Fixture, spacer, expandable washer, FH screw Workpiece mounted on

We have finally reached version 1.00!

Here is a list of new and improved features:

What's New

• Material Drop-Down list now shows 'X' on the row when the current Library Tool has Custom Surface Speed and Chipload settings.
• Load Tool dialog box now has Tool Type Icon. The same column shows a readable Operation Type Icon for finishing, roughing, etc.
• Drilling Tool Types now allow user to enter a custom Pecking value
• Milling Tool Types now have Editable Plunge RPM and Plunge Feedrate
• Milling Tool Types' updated Circle/Ramp Dialog now allows to specify whether ramp settings apply to Plunge feedrate of Milling feedrate

What's Improved

• Custom Speeds and Feeds tab on Edit Tool Dialog was improved with new buttons to reset custom Surface Speed and Chipload settings
  Glitch with certain diameters in metric mode being missed is fixed
• Load Tool/Cut Dialog box' Search was improved
• Load Tool/Cut Dialog box now features much improved tool and cut list with better readability and usability
• Ballnose Tools have been improved to better show changing effective diameter for different depths of cut.

Now, because a picture is worth a thousand words, here are some screenshots as well.

Updated and Improved Load Tool/Cut Dialog:

Note new Tool Type and Cut type Icons in the third column.Read More 

Hello guys,

I have just uploaded a latest release of HSMAdvisor v0.801.

In this update i only added a few calculators to the new Reference Tab.

Lets review all those calculators here.
And since i last time got repremended by mr rlockwood for making my post too long and dry, i will spice it up with a ton of pictures and even a download link. BTW you can download the updated version over here http://hsmadvisor.com/index.php?page=Download

There are 3 new calculators.

Those are:

• Scientific Calc -a child of my labor over this weekend.
  The standard Windows calc was driving me crazy with its small buttons, so i whipped up this one. Maybe later i will make it a separate pop-up window or something
• Drll Point Calc - a handy tool that allows to calculate depth required to make a countersink of set angle, and tip flat size
• Partial Bolt Hole Calc- allows to find location of equally spaced holes laying on an ark. 

Here is a full list of calculators available at this point in the Reference Tab:

Scientific Calculator

Bolt Hole

Bolt Line

Drill/Countersink Point Calculator

I plan to keep adding more and more new calculators and features and improving existing ones.

Should you have any suggestions, please let me know.

So far reaction to the new user interface has been somewhat mixed.

Those who like it, i guess keep quiet, and those who don't are voicing their discontent :)

I guess i need everyones feedback on this.

Please fill up following survey, so i can get a clearer picture of what i should be doing.

Here is a link to the survey on SurveyMonkey Website https://www.surveymonkey.com/s/HN75QGC

New User Interface Old User Interface

In this tutorial we are going to explore different options and techniques when programming cutter movement.

Lets begin with a simple part shown in a drawing below.

Basically it is a rectangular piece 4.00x2.00
For the purpose of simplicity lets make the depth of our profile (z- dimention) 0.75"

We are going to use a 0.5" dia endmill, again because it is a very common size and is easy to do basic math with.

I took a liberty of puting locations for our part/toolpath, so it is easy to extract numbers from the drawing just by looking at it.

Notice the green rectangle. This rectangle represents the path that the center of the tool will have to take to produce the part with required dimentions.
The thing is: because endmills have certain diameter, the center of the tool must be always offset by its radius.

There are two ways of doing that.Read More 

We all love getting positive feedback on anything we do.

For example hearing "good job" from our bosses. Or "nice work" from our co-workers....
Okay, Okay bosses do not normally tell anyone "good job", but anyway that would be nice!

I also like reading e-mails which people all over the world send thanking me for my work on FSWizard and HSMAdvisor calculators.
Telling their success stories and suggesting new features.

Most seem very surprised when they send a question on weekend and receive an answer withing a couple of hours.

Often people send pictures of their work and links to their own web sites.

It is nice that more and more professional machinists are using my software, but seeing it help create a work of art is a special feeling.

One of recent customers Daniel Gentile, uses HSMAdvisor to calculate cutting parameters for his custom knife production business.

Here is what he has to say:

HSMAdvisor enables me to efficiently do the math that saves me not just a lot of time as I can confidently often use higher speeds but also a lot of money, as I tend to break less of those expensive 2 and 3mm carbide tools that see a lot of use on my folder production. Also because I work with a dozen different materials - from D2 steel to Titanium to Bronze - and a lot of different cutter types and finish requirements it's just nice not to have to work with "guess-work" for the feeds and speeds.

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

PLEASE CHECK OUT OUR MASTERCAM X9 AND MASTERCAM 2017 HOOKS FOR MASTERCAM

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.
