Vince:

  Only a rigth or left facing tool can be angled. The definition of angled in LazyTurn is that the tool is Right or LEft angled, so just select it to be Left and then set an angle.

Thx guys, its starting to accelerate a bit as I get past the very hard sections..

Here is the next version, this allows for either direction in cutting. Only center tools can cut in either direction, a left tool can cut only left, a rigth tool only right.
You can switch directions in the Rough dialog by pressing the direction indicator.

Thx, Have fun,

Thx Chip:

  Ill check them out.

 Here is a new version. This version completes Phase 2 ( AntiStock gouging).

  This , however, is impossible to do without introducing a new setting you need to worry about.

Ive stated before , that center post tools will be considered safe to cut on both sides of the tool. Left tools, can cut only on
the left of the tool, Right post tools only on the right of the tool. Next phase will have the toolpaths cutting in those directions as well.
Center and left facing tools will cut Right to Left, and Right facing tools will cut left to right.

   This leaves the question of "How much" of the flank of the tool can cut. Ive opted to do this as easily as I could figure out by
adding a tool setting called "Flank Depth". If you were to measure fromt he tip of your cutting edge to the furthest away part of the flank
that is safe to cut, this would be the flank depth. This will greatly affect your end toolpath, so study the pic's enclosed till you understand
the concept. Note that on the tool, the flank that CAN cut is only to a depth of "flank" mm's.

  The result can be seen in the example cut path, note how the tool stays firther and further away from the desired cut since the tool would
otherwise cut deeply into the stock on the flank edge.. thats a no no.. , you can set for center post, or use a flank of zero if you dont care
about stock gouging.

Expect this one to be slightly slower, its doing much much more.

Hi Chip:

  The depth pass pass will change in meaning in radius vs diameter. The depth per pass is how much is removed per pass really, so in radisu mode 1/2 of the amount of diamter woudl be taken off.
Though I havent tested any of it in posting so I may have made soem wrong assumptions as I quickly got that section going.

  IIn the end, if you select diamter, and the object is 1" round, the end GCode shoudl reflect a 1" round item in either mode. I havent verified that though so yell if Im wrong. Rad/Dia is usually a perspective thing and depends on what referance one is using as to distance. But I could aeasily have futzed up.. I do that allot.

My appologies.. it finally locked up for me, though why it took hundreds of runs to match your immediate lockups Ill never know.
The problem was a degenerate condition I hadnt accounted for. This version fixes it.

Thanks

  hmm maybe the a offset is screwed

I'll run some tests

Thx

Paul:

  Ill wait ot hear back. , if it fails let me know. ...

Vince, I doubt its locked up, probably just doign too many passes, the math involved in finding an accurate
measure of removed material means that each pass it has to do makes it slower and slower, its a quadratic
time usage, so try a deeper depth per pass, or wait very patiently until its done, I doubt very much it locked up,
its just taking a long time to complete.

 Try deeper depth per pass, and youll see it gets longer in time the shallow the depth you use. But it will complete....slowly..
I dont recall the Crosshead file, how many passes would .025 do? ( in diamter mode that may be only .0125 off the radius
each pass..

Hi Guys:

  Sorry, had to delete an earlier post.

 This new version is faster, more accurate, and now knows how much material is left.
It can take a long time to generate hundreds of passes, but this is about as fast as it gets I think for this type
of algorithm.

  You should find this version much more robust, and accurate, not to mention faster. Radius/Diameter is taken into account in posting as well.

 Anyway, have fun,

Dennis:

 No, still no finish path, but its getting closer. Typically, the most that will be left on any section will always be less than 1 pass depth, if doing a 3mm depth, you may have up to 3mm left over and uncut. This is a normal roughing cycle though. The next step will be a semi-finish pass, which is a roughing cycle done with a finishing tool to remove anythign that woudl overload the finish tool during its final finish pass but I cant do that until I fix up rough stock gouging tests..thats currently being worked on.

hmm, Ill have to double check the radius/diamter mode.. and allow a smaller incribed circle on a gouging tool, ( there really is no such concept in a gouger.. but a radius of .1 would be a width of .2 at any rate, I just need to remove the limitation of width from a gouging tool is all I think.. and check the end code generator..

 Getting there slowly..
