Hey Y'all,

thought i'd share this with ya...

Dan wrote some thoughts about Quickmill toolpaths...
---------------------------------------------------------------------------------------

Choosing the tool for finishing is according with the biggest corner radius if this isn't smaller than 10mm maybe you can go with all in one go if is smaller maybe you need rest finishing.


If you want to present some quick milling features.


1. Roughing with an end mill.

Surface thick = 1.0 - 3.0
Tolerance = 0.1


2. Semifinishing with Lace or HSM Lace with the same tool size like the tool used to finish (should be ball if you do not plan to rest finish to proper peek tilt filleted corners!) this will assure you a genuine constant cut in HSM finishing this been very important:

SurfaceThick = 0.05 - 0.5
CuspHeight = SurfaceThick * (0.1 .. 0.5)
Tolerance = SurfaceThick * (0.1 .. 0.5)


3. HSM Finishing

Cycle:

If(the part is not too deep and is sculptural and doesn't have too many steep walls)

3.1 lace + 3.2 orthogonal lace or Zlevel orthogonal clipped for cusp height. (faces, dinos, phone, mouse) OR 3.1 Offset3D (0..45) + 3.2 Offset3D (45 .. 90) =

Under "3. HSM Finishing", what does the "3.1" and "3.2" refer to (e.g., "3.1 SideCut + 3.2 (HSM)Lace")?

3.1 and 3.2 are complementary suboperations of Operation 3 Finishing.

Boby's message is an old email and I think was posted here 4 months ago presents general guidelines in normal steel milling lets say metal milling. Of course we should present premiere features if we can in demo parts to differentiate better VX against its competitors.

Some of this concepts you can find in the thread "QM A use case for Thomas Minten" and some of them in the last templates issued by Bobby around. 1 month ago.


To keep it simple some of the golden rules are:
- cusp height ~= tolerance. (~= = around or a factor 0.3 .. 3);
-surface thick before finishing cycle for steel are around 0.05 - 0.5. The tool should be the same geometry with semifinishing too.
-cusp height for semifinishing (~=tolerance) 0.05 - 0.3.
-cusp height for finishing (~=tolerance) 0.001 - 0.01.

this are some meaningfull values for regular steel scultpural milling and if you chose 'em they don't create too much debate. Units are in beloved french system

sholud be general purpose hints related more with professional HSM steel milling than with VX or QM.
