Quite true Gary. I did spend some time reviewing it and then entered it into WinCNC line by line to observe (with no material or bit in place) and confirm. it was nice to see the machine behave as I expected. And it's nice to understand how spiraling tool paths are done.

Thanks

Mike, et al....
I've just posted this video: https://youtu.be/Ezdx2KVvFnU in this thread: http://www.camheads.org/showthread.p...1551#post61551 as a lesson for those that want to try.

Post questions with that thread so that the lesson remains.

The video can be seen by all, but the lesson is in the Owners section.

Enjoy! GC

Here is a little discussion on some walking sticks I hand coded on the recoil (from 3 years ago). I have found that hand coding the indexer is the quickest way to do most of the work I've ever needed on it.

Default Turning round wizard

I have been meaning to post my turning round wizard but need to make a video, here is a screen shot of the program:

You must first set Z0 on the center of your A axis



Setup:
Blank height 1.5
Blank width 1.5
Blank length 16
Distance from chuck 2 (the is where you set X0Y0)
Project length 12
Project final diameter 1.4
Router bit diameter 1.00
Spindle speed 14000 (use pull down menu)

Depth of cut either 0.125 or 0.25 in the example 0.25
Finishing pass yes or no in the example Yes
Router/spindle support auto on off in the example Yes


Here is the G-Code the program generates:

[**** YOUR SETTINGS ****]
[-----------------------]
[Stock material width] 1.5
[Stock material height] 1.5
[Stock material length] 16

Here is another video that shows some of the simpler aspects of toolpathing 2D vectors that are VCarved (2.5D) onto a 3D profile. Assuming an imported model as I used, all of these toolpaths can be generated with VCarve Pro.

One note: The Rotary Wrapped View was generated with Aspire.

This Rotary cutting option is one that has been in the works for a while. I am just getting to the finishing touches on the post processor trickery.

Like the previous post, assuming an import of a 3D model, this can be cut using VCarve Pro. It is a simple 2D profile "On Vector" with the toolpath applied to the 3D model.

Enjoy!

Thanks Gary, another great example of using the indexing lathe.
For those of you who may not know, Gary offers a wide range of training that can help expand your CNC operational knowledge. I recently received training on the indexing lathe from Gary and wish I knew about this training sooner. I now have a much better understanding of the process. I encourage anyone interested in learning more about using your CNC to contact Gary.

Well, here it is, the last of my videos based on lessons for the upcoming Aspire Camp at Jim McGrew's. After the Camp this lesson becomes part of the "Advanced Rotary" training.

Setup for this job is to develop a 2D profile. Since I want to test all of these methods with VCarve Pro, the 3D flat model was generated by Michael Mezalick and imported into VCPro.

The following cuts are generated 100% with Vectric Software. VCPro or Aspire. No hand coding or trickery to the posted file. One note: The continuous rotary profile with the 1" ballnose uses a special purpose custom post processor developed for my SideWinder machines.

Attached pics show some Aspire Screenshots of the rotary wrapped view and the screen layout that shows the model and EVERY vector used to generate the toolpaths. Note that the small beading bit cuts were not in the model.
