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!

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 

HSMAdvisor the Hook for MasterCAM x9 has had massive changes since the last update

• Completely redone Operation Import/Export functionality
• Added "Insert Operation" command (Add it to MasterCam toolbar through Customize->Toolbars->HSMADVISOR->select item,select toolbar-> Add..)
• Reworked MC Toolbar Icons
• Better tool Recognition
• Added support for ALL milling (2d, 3d, HST) operations. 
• Fixed a huge number of problems including those with coolant, tool numbers and some unsupported operations.

HSMAdvisor hook for MasterCAM currently supports only MC x9.

Due to large amount of work I have done on x9 hook I decided to not port it to support x8. I simply have no time resources to do so. I only have one life you know!

Later versions of MasterCAM will, however, be fully supported.

This is update is the last one before a pretty big new additional feature being added to HSMAdvisor. So i cleaned up all the little glitches and made a lot of invisible to naked eye improvements.

Without going into detail i can tell you that those features normally cost users of other software products upwards of several hundred dollars, and they will not be without a cost to HSMAdvisor users too.

This feature will be optional and only those who need it will be able to purchase it as an add-on Later this feature will become a separate software product with HSMAdvisor add-on being just a small part of it.

Development of HSMAdvisor will continue as normal.

 What is new and improved in this update:

• Improved function of Tool Tables. Removed flickering. Faster Filtering and scrolling.
• App Icon changed
• Modified over 45 Degree Ramping Feedrates for milling.
• Fixed Cloud Machine Upload

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.
