HSMAdvisor 0.023 Has been released

April 7, 2013, 11:26 pm by Eldar Gerfanov

This release is a major step forward.
We are starting to wander away from just Speeds and Feeds calculator part of the project.

Version 0.022 was a little buggy.

All reported and known bugs have been fixed.

New update version is 0.023

New features:

  • Threads page: You can now get thread cutting and tapping data for most popular threads in north America (UNC/UNF/ISO).
    The list of supported threads and features will grow according to necessity and user feedback.
  • Machine Profiles now have 2 new buttons: Clone and Import.
    Clone button simply copies selected machine definition with a different name.
    Import button is needed to be able to update/add machine definitions from default machine list. As users modify and customize their Machine List, thay are now able to add machine definitions hassle-free from default_machines.xml file that is supplied with every update.

Bugs Fixed:

  • Sticky Ball nose check box

  • Max HP improperly rounded

Additions:

  • Thanks to Greg Jackson and Matt Doeppers from Tormach i was able to create Horse Power/RPM curves for Tormach PCNC770 and PCNC1100 models (if you install over previous version, you can use import function to add those machines to the list)

Digging for Gold

March 28, 2013, 9:42 pm by Eldar Gerfanov

I recently had to machine an aluminum mold cavity.

7 inches deep. With 5 degree wall draft and a 60 thou radius going all the way down. Roughing was not an issue, but for semi-finishing and finishing i had to manufacture these two extension holders.

Both tools have runout of less than 0.001

The one for bigger 3/8 tapered ballnose cutter is shrink fit- i mounted it using torch.

The smaller tool is a 3/32 tapered ballnose cutter from Harvey Tool.
I could not bore to correct size, and had to ream right on.
The tool is mounted with a set-screw from both sides to prevent deflection caused by unequal clamping pressure.

HSMAdvisor 0.021 Has just been released

March 17, 2013, 11:25 pm by Eldar Gerfanov

New things: None.

Well not really.

First of all alot of small bugs has been fixed.

Second of all i added a neat picture to Drilling operation.

It now shows what each drill specific field means

Also. Unfortunately all current license key holder will have to get new license keys.

If you currently have a license key, please e-mail me your new Computer-ID
And i will send you a new license key.

NOTE:

If you are installing over previous version of HSMAdvisor, you are encouraged to perform complete uninstall of the old version.

Othervise what happens is old settings file is not compatible with the new one.

This will cause Default Tool Type, Tool material and Coating presets to get lost and you end up with a funny looking FSWizard page.

Correcting this is extremely easy:

You need to select some tool type (IE: End Mill), select some Tool Material (IE. HSS) and finally select some Coating (IE. NONE)

This will fix the problem.

Attached below is a screenshot of what it looks like when settings mismatch happens, not a pretty sight i agree, but there is no need to panic.

(Note to self: add version check for every file)

FSWizard and HSMAdvisor status update

March 15, 2013, 10:46 pm by Eldar Gerfanov

We have alot of stuff coming.

First of all HSMAdvusor is being particially rebuilt to fix one current issue and provide easier frature implementation in the future. I will try to push update this weekend.

FSWizard:Online has not seen alot of updates in quite some time. A decision has been made to persue mobile web application with bacend running on the server. Currently i am exploring options, modifying mobile version to work with google's jQuery mobile framework to allow seamless deployment across al platforms.

Below is a screenshot of the mobile web app being developed right now.

An attachment like this is sure to save you some time and money running your lathe unattended

And here is a sketch that i used to make it

One more way to Resharpen a chewed up endmill

March 10, 2013, 10:02 pm by Eldar Gerfanov

Some time ago an unknown colleague had borrowed an end mill from me.

Have i had been there i would have stressed that it was aluminum specific cutter and that it should not be used on steel.
Unfortunately i was not and it did not occur to him to ask somebody who would have known better.

Next time i look into my drawer i see this.(first picture)

Now we have a tool and cutter grinder to sharpen the OD of an end mill, but chips were so big, i would have to grind off maybe 20 thou of the diameter on order to get rid of them.

Our TC grinder does not allow to re-flute end mills, so i had to do it holding end mill in my hands.

First i picked up correct angle, and then i slide end mill upwards, turning it at the same rate as to follow flutes.

It came out better than i thought.
I was not planing to use it for finishing anyway.

And it lost only 5 thou in diameter after this hack-regrinding.

    Why do we machinists need a feed and speed wizard

    February 14, 2013, 10:44 pm by Eldar Gerfanov

    Sometimes people ask me: "I tried your calculator, and i liked it, but it seems to me a little too aggressive...do you actually do any testing?"

    Well, to those I say that not only i do testing, but i run production jobs 100% calculated with my own HSMAdvisor.

    Many machinists say that nothing beats an experienced operator holding his hand on feed hold button and playing with speed and feed override trying to find the "sweet spot" where cutting speed and feed rate are maximized and chatter is eliminated or reduced.

    And it is correct, but not any machinist is experienced or actually knows what he is doing.
    Many machinists also finish their apprenticeship program and never learn a single thing about new tooling types and materials since. They bag years of experience, but their knowledge is stuck on a level it was when they first got their license.

    Also not a single person can possibly know cutting conditions for hundreds of materials and remember all of the jobs he had ever ran.

    This is where tool database comes in.

    Not only can you save tools to cut down and in many cases eliminate entering parameters for every calculation.
    But you can (and should) save cutting data for each particular case.

    A single tool entry can contain an unlimited number of cuts attached to it, so machinist never has to remember everything.

    Here is a i made video of slotting D2 with variable helix hi-performace endmill.

    Material: D-2 Tool Steel 200-250 HB
    Tool: 0.500in 4FL Carbide TiAlN coated Solid HP End Mill
    Speed: 360.0 SFM/ 2751.6 RPM
    Feed: 0.0023 ipt/ 0.0094 ipr/ 25.76 ipm

    Engagement:  DOC=0.330 in   WOC=0.500 in
