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 axis to give 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 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 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.

Proper machining depth and width of cut are just as important as proper Speeds and Feeds. 

This is not only importanttant for professional machinists, who are machining on the edge of their tooling and setup capability, but also for hobbyists, who often face limits from the machine rigidity side of the equation.

HSMAdvisor Speed and Feed calculator has a unique tool used for figuring the best engagement values for each particular cut you are making.

It is called Performance Slider. And it adjusts expected load on the tool and machine depending on your preferred machining mode.

Check out this video I made that explains Performance Slider' functionality:


Suggested new feature to HSMAdvisor: Quick G-Code Wizards

September 20, 2015, 4:54 pm by Eldar Gerfanov
Recently i have received a very interesting suggestion, which i would like to discuss with you, guys.
 
A HSMAdvisor user wants to be able to create quick G-Code snippets based on the Tool and Cut information that HSMAdvisor has.
 
G-Code Wizards will allow you to quickly create a stub program for various standard machining operations.
 
For example you calculate speeds and feeds for drilling.
Then you have the ability to create a G-Code program based on your input like so:
 
T15 M6(T15 1/2" HSS Drill)
G54 G0 G90 X[Hole1_X] Y[Hole1_Y] S1500 M03
G0 G43 H15 M08
G81 G98 X[Hole1_X] Y[Hole1_Y] Z[Depth] F15.0
X[Hole2_X] Y[Hole2_Y]
X[Hole3_X] Y[Hole3_Y]
G80
G0  Z0.5 M09
G0 G91 G28 Z0 M05
 
All with a few clicks of a mouse.
This piece of code with minimal modifications you can then quickly insert into your program.
 
What do you think about it?
 

FSWizard:Mobile Has Been Featured on ENGINEERING.com Website!

September 20, 2015, 4:26 pm by Eldar Gerfanov

Quote:
Zero_Divide's FSWizard speed and feed calculator is the latest professional-grade mobile calculator to hit the i0S and Android stores.

For those who aren't happy with the accuracy of the speeds and feeds generated by their CAM software, FSWizard may be your solution. Like a Swiss army knife, it also includes a toolbox of essential charts and standalone calculators to make life easier for machinists.

Check it out here: http://www.engineering.com/CAM/ArticleID/10667/First-Look-Speed-and-Feed-Calculations-Go-Mobile-with-FSWizard.aspx

Can not say it gave me an immediate influx of new sales (although every bit helps!). I guess most of the sales are driven through this web site and the buzz around HSMAdvisor Advanced Speed and Feed Calculator or the free FSWizard:Online calculator.


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:

G-Code Name Motion Style
G81 Standard Drilling Feed-In, Rapid-Out
G83 Deep Hole Peck Drilling Incremental Feed-In by Peck Distance, Rapid Out, Repeat
G84 Right Hand Tapping Feed-In,Reverse Spindle, Feed-Out
G85 Reaming/Boring Feed-In, Feed Out

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.

New stuff in HSMAdvisor 1.191

September 13, 2015, 10:01 am by Eldar Gerfanov

 

We have some (I am sure welcome) addition to our family of tool types supported by HSMAdvisor.

The new tool type is "Boring Head".

This tool is used for finishing holes on milling centres. Also in this release I have made a lot of improvements to operation of myCut Database and revised ssuggested depth of cut for milling tools when used at low radial engagement.

More details on the HSMAdvisor Download page.

Regards!

 


Key factors Determining Success of High Speed Machining (HSM)

September 12, 2015, 8:29 pm by Eldar Gerfanov

As a developer of a very successful line of speed and feed calculators I sometimes get questions like : "I calculated speeds and feeds for a conventional toolpath. Got 5.5 cubic inches MRR(Material Removal Rate). And then I calculated S&F for the same endmill with HSM parameters turned on and got almost the same amount of  MRR! What is even the point in using HSM parameters?" -they ask.

I would like to clear some things up for my friends.
In this article I will explain exactly WHY HSM machining is better and HOW to achieve better productivity and tool life.

For starters here are the main features of a HSM-capable cutter:

As usual there are several components of HSM that need to be present in order for it to work to its fullest. These are:

a) Machine
b) Tool
c) Workpiece geometry
d) Workpiece material

I intentionally did not number these as each one of those is equally important.
