Re: Creating CNC roughing and finishing passes

Hi Herb, Couple of things: 1--Nothing that I'm suggesting addresses Finish surfaces, only Roughing. 2--What you show is the effect of the step-down and step-over sizes which are large as shown. In all cases--even with "true" 3d path generation, the result is an approximation of the model. If the ste...

Re: Creating CNC roughing and finishing passes

Well, if you like Chris's example--and, I do as well--but, you don't like the iterative aspects of it, then try buying what I'm selling :lol: Here's a cut resulting from an example Cone, that I then used as a cut-tool on a larger cylinder. ConeCutExample.png Easy-Peasy, so far. Then, I made a Job in...

Re: translate a point with a vector direction.

Is there already a tool (with GUI) for "translating" stuff in general? Not sure. I suspect from a GUI use standpoint, there exists placement for each object. If you double-click on an object, you can edit the translation and rotation increments, but it's not clear what this affects. One thing that ...

Re: Lathe Features

Hi Dan, Not sure what code interests you, but you're very welcome to anything I can offer. I have essentially zero practical lathe experience--limited to turning small parts in my CNC spindle. It is a fascinating endeavor you've taken on, and I'm happy to bounce ideas if nothing else. Something that...

Re: translate a point with a vector direction.

I believe, but am not sure, that you want to create two vertex points, relative to a known input point (M1), and two known vectors(Vec_F1_Norm, Vec_F2_Norm), and a fixed offset distance of 2mm for each, and what is confusing you is that the normal vectors are translated away from the XYZ axes. It wo...

Re: Creating CNC roughing and finishing passes

Hi Herb, Just kidding on the "sassy" comment :lol: It's a funny word. I know what you mean about OCL legal limitations no longer being of concern. What I meant was that unless I misunderstood Russ, what he did was use OCL as the engine to derive paths from shapes. What I believe he did was put toget...

Re: Lathe Features

Hi Dan, Looks like you're making good progress. I'm glad if anything I offered is helpful. I've put a fair amount of thought and effort into understanding the relationships that exist between cutting edges and job models, so figured if any of it translates and is helpful to you, I'd throw it out the...

Re: Creating CNC roughing and finishing passes

Herbk--you're always sassy;) Unless I'm mistaken, Russ has taken the step of putting some controls onto the 3dSurface tool, which leverages OCL. The 3dPpocket operation utilizes a fundamentally different function, and already has inputs for step size and step-down size. One thing I found interesting...

Re: Lathe Features

I believe that touches on some of what you are trying to accomplish. I'll leave it there but if there's anything I can help with, don't hesitate to ask.
Regards,
Josh

Re: Lathe Features

While I did not do this here, the general approach could be something like: 1. Determine the "profile" shape of the job-model, in the range along the Z-axis, excluding the Chuck. Much as you have done, a cut of a plane, at the lathe's "Y" height, bounded by the stock radius, and length generates a s...
