Workpiece definition - OSP5000L

[RRMEB]

I'm working with postprocessor documentation for Okuma lathes with OSP5000L and OSP7000L and will also try to generate workpiece definition in the NC-code.

I can not find very much documentation for this in the manuals and have so far tested simple profiles like this:

CLEAR
DEF WORK
PS LC,[0,0],[20,60]
PS LC,[0,0],[20,20],0
END
DRAW

I can't figure out how to draw arcs and angles. Is it supported by these units? I've tried to run some examples from newer OSP-units but it only results in an UGC-alarm.

Does anyone have an example how this is done?

I have never figured out on the older controls. I think they wont do it. You can do "kinda" tapers by creating squares smaller and smaller. Thats how IGF posted it anyway.

Look up the "OSP Operation Manual" - Amination Data section
it may also come under the APT manuals for "One Touch"
It gives info on how to have tools and the stock materials drawn correctly

Milling stock is built by the use of cylinders and cubes, holes use the same sort of primatives but are subtracted to give a cavity for 2D and 3D views
Lathes are 2D entities of lines and arcs for a very basic view of the toolpaths and remaining stock

G83? Please check with Your manual. I can't tell if this control supports blank shape definition. U10L is the first where I used it for sure. You describe the shape as for LAP, G83 is only difference in code.
Check with simple shape if You don't get any alarm of G83.
The "DRAW" variables what You mention is a different thing. It's just basic blank description. cylinder and hole inside. There are also different coloring and patterns for animation to have difference of materials.
Note: corrected. M83 was initially instead of G83

Thank you very much for feedback!

Algirdas: It's the Blank Description I'm looking for. I think you mean G83 (not M83) which is LAP function for effective turning of shaped blanks. I don't want to use this cycle in the postprocessor as I have more possibilities letting the CAM-program decide the path with "long code".

Superman & underthetire: I've checked the manual and it may look like OSP5000L doesn't support arcs and angles. It says that you can use up to 6 OD's (external diameter) and 4 ID's (internal diameters). I will test this on the machine. If it's possible with unlimited blocks I'll try to build the arcs using squares.

Thank you!

oh yes, thank You for correction. I will mark on errorneous comment also

Just imagine opinion of operator about You, when he needs to correct some minor fragment of shape on-the-fly

[RRMEB]

Have just tested a shape with 12 blocks. This works fine!! Has also tried to build up a shape with tiny squares and 1mm variation for each step. With poor screen resolution it appears as a perfect chamfer!

I think this must be the solution...

Algirdas: I agree! G83 is a handy cycle for the operator!

[Algirdas]

so it works on OSP5000?

is good for show also. I don't need to take new blank workpiece - I can use "the part" already cut instead of a blank.
Single shape description is better, sure. LAP and finish cut can use the same shape description.
I used even the same for blank shape definintion with variables.
