A few days ago one of FSwizard:PRo users questioned me over how FSwizard works.

The way SFM calculates seemed off to him.

As a result i made a quick sketch for him, that i thought i would share here.

Omar was asking me how come SFM seemed wrong for a 1" dia ball-nose cutter when making shallow depth cuts.

The sketch above shows exactly why.

On the left part we see a cutter engaged into the material to the depth equal to its corner radius.
At that depth the maximum effective diameter is achieved. So an old good RPM=4xSFM/Dia formula would apply.

But at shallower depths, effective diameter of the cutter is reduced.

At 0.1" depth of cut, effective diameter would only be around 0.6"

In fact it goes to zero at the very centre. So a higher RPM will be required to achieve the recommended cutting speed.

In the same thread i also explained how DOC/WOC balancing works.

So if you are interested - read on.

Here is the thread http://zero-divide.net/index.php?page=forums&shell_id=170&article_id=4590

One of the latest additions to HSMAdvisor speed and feed calculator is the ability to set manufacturer-recommended speeds and feeds for work-piece materials and groups of materials.

Here is a YouTube video walk-through showing how to add S&F tables into the program https://www.youtube.com/watch?v=AJOgWfgy99U

HSMAdvisor uses Brand Name and Series Name to assign speed and chipload tables to tools.

A new "Speed and Feed Source" (S&F Source) indicator has been added to quickly tell user which speed and feed table is being used right now.

The latest release of HSMAdvisor is now available on Download Page

There have been many important improvemnts. So please download this update ASAP

• Important!: Add Tool Error fixed
• Expanding and then contracting window would sometimes cause layout to break. This issue has been fixed
• Layout problems when using non-standard Windows scaling were fixed.
• Window resize by dragging one of its edges has been turned on.
• Program Launch Time was improved

Recently i noticed that I (and everyone else) could not add new information to my website.

The issue affected everything. New support forum posts were getting rejected, you could not save online calculations and even automatic payments were not saving in my online database.

Turns out my hosting (the company that hosts my web sites on their servers) changed a bunch of settings from their end.

This caused all the issues many may have been experiencing.

Now everything has been fixed. In fact it only took me half an hour to fix things, but 3 days webservices were immobilized until i noticed the problem.

I also made some changes to HSMAdvisor program.

In version 0.811 i have fixed an annoying glitch that crashed the progam when less than 3 days were remaining on the trial.

It did not affect paying customers, but i guess it cost me a few of potential ones.

I guess it is another drawback of releasing updates as often as i do.

New Things:

• New "Indexable Drill" Tool Type
• Some tool will now have Usage Tips in the warning box, IE new Indexable Drill Tool type will have recommendations to use through coolant.
• New Buttons on Tool Geometry pane:
  [Edit As New] button allows to quickly drop current tool and use its data to create a new one
  [Add Tool] Allows to quickly add tool to the library of your choise
• Edit/Add Tool dialog now allows you to choose tool library when you add or edit tool information data into the database

Whats fixed:

• On systems where comma (,) is used to in place of a decimal point, selecting Tap tool type would throw an error.
  This glitch has been fixed in this update.

What's new:

• Revised chiploads for smaller endmills.
• Revised recommended Depths of Cut for different material types for endmills with various number of flutes.
• Improved Deflection model to include cutter lead angle.

In this update i have re-visited speeds and feeds area of the calculator.

Recommended Depth of Cut and Deflection calculation was revised.
At the same time Chiploads for endmills smaller than 3mm or 0.125" were reduced in half.

This resulted in most things regarding actual Speeds and Feeds remaining the same, but i believe this update works better as it considers material type and number of flutes to calculate recommended depth of cut.

Also Deflection calculation was changed for tapered endmills
