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.

The latest update of HSMAdvisor Advanced Speed and Feed Calculator resets trial clock for all users.

So if you tried it before and were not sure if this is for you, you can use it again absolutely for free for another 30 days.

As usual you can download the latest release over here -> http://hsmadvisor.com/?page=HSMAdvisor

Please help us make HSMAdvisor a better software product.

Tell me if we are heading in the right direction.

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.

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.

Added HSMAdvisor Cloud Services that allow users to Download and Upload their Machine Profiles.
You can now access your Machine Profiles from everywhere!
Users can also download each-other's Machine Profiles, uploaded as public.
Machine Power Curve Estimation wizard to help users map their Spindle Power Curve
Right-Click mouse click on selected rows launches a pop-up menu, that allows to insert and delete rows from the Power Curve table

I often get email questions asking for clarification on merits of use of HSM And Chip Thinning check boxes when calculating speeds and feeds with HSMAdvisor and FSWizard calculators.

In this new help article will try to explain just what HSM means and in which situation you should use it:

Hopefully this will fill in the gaps and help our users to get more comfortable with our software.

One of the most versatile ways of clamping irregular -shaped parts is with use of soft jaws.

In this one I had to machine a triangular-shaped part from two sides.

It is going to be some sort of a part holding jaw for a robot.

So step one: Machine one side of the part in vise. hold on to 1/8" of stock. So make sure to cut your part on a bandsaw oversize.

Step Two: Bolt soft jaws to your vise and machine a pocket using outside contour of your part.

Be sure to relieve corners.

Step three: Clamp your part in the soft jaws and machine the second side of your part.

One important thing to consider is: this method is not very accurate. depending on the size and a shape of your part you may be able to hold it within 0.001" though.

See attached photos of the steps below.

I had some unfortunate troubles initially releasing the mastercam hook this month.

But thanks to the feedback from my users and the fine folk from eMasterCAM.com community they are now over!

Updated installer is available here-> http://hsmadvisor.com/index.php?page=HSMAdvisor_for_MasterCAM

Cheers!

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.
