Just decided to store here the quotes that i liked.

And those that made me think about purpouse of life and Univerce.

The ONLY FREE CNC Speeds and Feeds Calcualtor

Confidently calculate cutting conditions for hundreds of work-piece materials and of combinations of tooling types and coatings.

• Accurately Estimate cutting forces involved in machining process and prevent tool breakage.
• Estimate machine power requirement and help choose best tool for the job.
• Suggest safe and practical Axial and Radial engagement values.
• Compensate for reduced-shank, long and extra-long tools.
• Improve cycle times and tool life
• UNIQUE feature that allows to set comfortable levels of cutter torque and deflection and prevent cutter breakage.
• Ideal for use as your Dynamic / Thoroidal / Truemill calculator

If you cant, then dont clamp it at all!.
Skin it!

In here i have to program and machine several sets of roundish aluminum pieces with +/-0.001" outside tolerance. and within 0.002" thickness repeatability.
Instead if fixturing it one by one i decided to skim cut a 33" x 23" x5/8" to within 0.0015 flat. And then machine each piece completely leaving .005" outside to holt everything together.

Worked out great.

Needed to do alot of side drilling/milling/tapping on our moulds lately.

So I quickly designed and whipped up this custom indexing fixture that allows me to mount almost anything to it.

Face plate has several tooling dowel holes on front side to locate work piece.
On the back of face plate there are 36 3/8 dia reamed holes spaced 10 Degree apart.

Housing has a big 5.0"Dia pocket in the front into which the face plate's hub fits in with 0.001" clearance
Housing also has corresponding 3/8dia reamed holes spaced apart 9 degrees. This allows me to index the face plate with 1 degree increment.

Design time:2 hours, Machining time: 2 hours.

It has just been released.

Please test it out and tell me what you think!!!!!

Here i will show you how to calculate Tool Engagement Angle using tool diameter and Width Of Cut (radial deopth of cut)

Lets first draw a pretty image that shows us everything we need.

Where:

• r: Radius of the cutter = Diamater /2
• a: TEA - Enagagement angle we are trying to find here
• WOC: Width of cut or RADIAL Depth of Cut
• r2: The difference between r and WOC, r=r2+WOC

Below we develop 2 formulas that allow us to find TEA and WOC

Tired of printing out Operation lists and then wasting time adding setup information by hand?

There is a neat and easy way to replace standard Operations and Tooling lists with something very compact and usable.

Here are config files i use at my work to create Setup Sheets and tooling lists right from SurfCam.

1. First make sure you backup you Operations.cfg and Tooling.cfg files in case you want to go back (VERY NOT likely)
   Those can be found inside your V5 or V6\Config directory.
2. Unpack contents of the attached ZIP folder.
3. Copy .CFG files found within into your V5 or V6\Config folder.
4. Copy folder "images" into "C:\Surfcam" directory, if you want also tool images to show with tooling list.
5. Go to SurfCam Options and in section Setup Sheet select "Current" from several other choises.

Thats it!!

UPDATE!!!!!!

• Operations list NOW highlights table rows when you move the mouse over them.
• When you select ANY text on Operations List, the same text will be highlighted over the whole page!!!

Optimizing Peck Drilling for Deep Holes

Peck drilling is often necessary when machining deep holes. However, with the correct feed and speed settings, pecking is unnecessary for depths up to:

• 3× diameter for standard drills
• 5× diameter for high-performance parabolic drills

For deeper holes:

• Up to 10× diameter → Up to 5 pecks for regular drills, and up to 3 pecks for parabolic drills
• Beyond 10× diameter → Constant pecking is required:
  • 0.5–1× diameter per peck for regular drills
  • 1.5–2× diameter per peck for parabolic drills

Since programming requires specifying a peck amount, here are the recommended values:
