extracting wcs from post

[pip]

Is there a way to extract wcs information in the post.. I will look through my v9 post CD later, but you lot are allways quicker. I need to know what angle to rotate the tables using WCS information..

Hi Pip,

 

Are you trying to get rotary output in your code by using WCS, or do you want to read a series of operations and just get the B and C angles to program those in manually? Most version X post processors automatically calculate and output the rotary angles as long as you set it up correctly. Typically in Version 9 you would use one WCS and then use different "Tool Planes" to force Mastercam to output the rotary move. Mastercam would calculate the angles between your current Tool plane, and the new Tool plane and output the correct angular move. In X, depending on how your post is setup, you can use multiple WCS planes, or multiple Tool planes to accomplish the same thing. It really depends on your post. If you give us a little more information about what you are trying to accomplish we can help you more specifically.

 

Auf Wiedersehen!

Thanks for the reply, what is happening is, I am setting up WCS's to get the angle outputs in the code, but its not happening. We are using Xmr2 and X2. On Monday I will place a simple file and its output on the FTP.

Angle outputs as notes or actual rotational code?

[pip]

Actual rotational code..

I have been playing with the mpmaster post for X, but its still not puting out rotational moves I want.

If I understand you correctly, you are trying to use the WCS to output

 

G54 = B0

G55 = B60

G56 = B120

 

A WCS by definition starts out in a TOP mode any angular output is handled by the T&C planes being rotationally different from the top view, that is what causes the rotational output.

 

So can you set up a WCS, I don't think, you could set up different planes to get the output however.

[Hardmill]

Pip open the "PLANES" button in your toolpath parameters

and set the WCS to your Orig (first) postition, B0.

 

Leave your T/C planes as they are. This will give you the needed rotation in your g-code.

Hope thats what you need.

Bascally the WCS takes the plane that you create being the WCS, lets call it face you want and make it the new top.

What you want is to make this a plane and to have MC see this as a plane change. (like waht Hardmill is showing above)

you at first set this as a WCS to set up this new pane but when you toolpath, use the Cplane & Tplane to path in and MC will see the change in Ppane and out put the rotation.

 

Will review your file to on monday.

Hope this makes sense.

Do what Hardmill said...

[pip]

Thanks for all the advice, but I have had a **** of a day today, so I haven't had time to sort the file out, and place it on the FTP. Maybe tomorrow..

Thanks everybody for your help, please wait until tomorrow..

what am I doing wrong, using mpmaster X

[cadcam]

Are you doing 5 axis or 4th axis?

The problem is right in front of you. WCS makes the plane the top.

 

Change the toolpane to your "Left Hand Side" and set the Working coordinate system to top and look for the B and C values.

Yeah alot of people make that mistake and easy to do. WCS is for making new work coordiante at each one thus making a New offset that is the Z+ up, X+ right, Y+away from you for each WCS. So if you set-up a WCS you in essecne are making every new one a new 0,0 for posted code thus cancleing out any indexing or rotation. You need to use One WCS then rotate your C-plane/T-planes to make your indexes for your 5 axis or 4 axis toolpaths.
