A few tips on surface milling with ballnose endmills.

November 18, 2013, 2:13 am by Eldar Gerfanov

Since surface milling is more than half of what i do for a living, I decided to share some of my tips on that topic.

Generally you want to create a continuous toolpath that does not change directions too often.

Changing directions slows the machine down and reduction in feedrate affects deflection of the cutter. Different deflection means you get gouge marks on your surfaces.

When you have a long narrow piece its better to go along the long side to save on time and machine wear.
Also going along the longest side reduces the number of direction changes you will have to make

When milling cavities you need to first rough, then semi-finish then finish.

Leave 15 thou after roughing, 3 thou after semi-finishing and finish to zero. All with progressively smaller tools.
5 thou stepover will give you very good finish on most ball mills
3-5 thou chiploads are very common for surface finishing.

Ball mill will always give bad finish on shallow areas- the center is not cutting, but dragging around.
Also straight portion of the flute acts as a wiper and reduces scallop that the ball portion creates.

This is why going from top to bottom is safer and yields better surface finish.

The closer the wall taper angle to the taper of the flutes the better finish you will get.


There is another reason for always trying to go from top to bottom.

When taking material top to bottom you engage stock closer to the tip of the tool.

It makes cut more stable. It is more safe because you are less likely to bury the tool in stock unexpectedly.
Do not go from climb milling to conventional UNLESS you need to save some rapid time.
Pick up only climb milling and you are good to go.
Changing from climb to conventional will cause tool to deflect away from the work on climb and into the work during conventional pass. You will see zebra marks all over your surfaces.

 


New materials are here!

November 18, 2013, 1:17 am by Eldar Gerfanov

I have just completed revising HSMAdvisor's material library.

Around 20 different materials have been added.
Some speeds and feeds were adjusted as well.

New library is not yet available in the official release, but you cen get it as a separate file from here

Just scroll to the bottom of the page there and download the file.
Instructions of how to use it are there as well.

Once a new update is ready to be published i will include the new library into the official release.

The list of added materials includes Toolox, Weldox and other pre-hardened steels.

Also graphite was added to hard non-metals.


FSWizard 1.21 for android is now available

November 17, 2013, 1:46 am by Eldar Gerfanov

In this update i fixed some of the annoying things that were present in my app before.

Firstly i have totally changed the way app renders. Instead of using gradient backgrounds i am now using background images everywhere. This prevents glitches that some users reported before.

Then main menu now takes the whole screen. Small but descriptive icons were added to ease the navigation. Also scrolling problems for all of the devices were fixed there.

Phone Back button now exits the main menu or the virtual keyboard.

To shut down the app you have to tap Back key twice. This prevents acidental exits.

Phone Menu button opens main menu now. So the workflow is a lot like in the rest of android apps.

As a test i gave it to my wife to try out. She was pleased and managed to run through the whole app within a couple of minutes and never got lost. She especially liked menu icons, said they looked cool.

Email me or post on forums if you have any feedback.

The sale is over.

November 14, 2013, 12:29 am by Eldar Gerfanov

The sale is officially over!

I would like to thank everybody who INVESTED in HSMAdvisor and FSWizard development.

Thanks to your support and funding i am able to continue working and improving upon my and YOUR software.

In a little over a year we have done a lot of work and there are many more amazing features in the pipeline. Anything we can dream of can be acomplished if enough effort is made.

Thank you.


Sigh, me sad..

November 12, 2013, 12:03 am by Eldar Gerfanov

Today i got another review on my free FSWizard Android app.

It wasnt bad. The guy gave 4 out of 5 stars, but then he added that he would gladly pay 4-6$ and that 18$ for the pro version is beyond reasonable.

I should have shut up.

But i never can.

I replied that the price is what it is, explaided my point of view and thanked him for a good review.

He then changed his rating to just two stars...

And then denied that he initially gave me 4!

Sir. Take your business somwhere else.

Update: guy changed his rating to one star and wrote he does not know what 4-6$ i am talking about.

Friends, if you know a guy named David Alwine, keep away from him. He is an utter lying jerk!

Interation of CAM drilling operation with HSMAdvisor

November 8, 2013, 2:00 pm by Eldar Gerfanov

This is my first try at making a tutorial.

I wanted to show how to set up integration with you CAD/CAM program usi g drilling cycle as example.


Update: Halloween sale has been extended untill Nov 13th

November 7, 2013, 9:22 pm by Eldar Gerfanov

I have decided to keep the sale on HSMAdvisor until November 11.

This should give everybody just enough time to make up their mind.

Update

The sale has been extended until November 13 th.

I have received not one but two letters asking me what happened to the sale prices and why it ended so soon.....

Well, you guys have 2 more days to decide!

Also i have uploaded an update to HSMAdvisor that fixes problems with the integration module giving out errors.

Now everything works fine.

HSMAdvisor 0.610 Has just been released

November 2, 2013, 6:17 pm by Eldar Gerfanov

In this release I have added CAD/CAM integration.

Please read the latest tutorial in HSMAdvisor Tutorials section here
This is a pretty Unique way of doing it.

It is still in the beta-mode.
But it is fully functional. I have tested it on MasterCAM and SurfCAM with great results.
While some functionality is not supported well on all cadcam packages, it is still much better than nothing.

Please send me your feedback on how it works with your CADCAM package.

I have also added a list of recently used materials.

Now material list will have 6 recently used items at the very top of it.
Later on i will allow user to enter whatever number of recent items he wants to see there. But for now its just 6.

New Computer ID and New License keys

Starting from this release i have changed how Computer ID keys are generated.
This was done to fix problems some of the users experienced when they added or removed additional hardware on their computers.

New Computer ID's mean License keys have been changed for all users as well.
Not to worry though, License keys will be automatically updated for all of our users, so no action from their side is required.

If you have active license. You will get a message telling you what happened and your license file will be updated automatically.

Some bugs got fixed as well.

All of them were pretty minor, nothing to write home about.

Material definitions got updated as well.

Added several materials, updated speeds and feeds for tool steels and stainless steels.

I still have to add some of the previously requested materials (like Weldox Graphite, etc) to the list.
And i am planning to add it in the next release.

Chiploads for micro-milling were changed as well.

Chiploads for micro-endmills (below 1/16 dia) were reduced significantly.


HSMAdvisor Integration with CADCAM

November 1, 2013, 10:53 pm by Eldar Gerfanov

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.
