Vectors

[cijunet]

Hi
What should I do in order to get my part programmed with vectors (I,J,K) instead of radius. I use MC X Mill.
Thank you

Make a backup copy of your post processor first.
Then open it and look for the line:
arcoutput : 0 #0 = IJK, 1 = R no sign, 2 = R signed neg. over 180
under general output settings
change it to (0), save it and post a code.

That will force the I,J,K for you

Make sure you check your code piror to running a program on the machine.

alternatively, go machine type, machine definition, click icon to edit post,here there are a load of user options for that particular post under the arcs tab you can change from radius to unit vectors (i,j,k). Any probs let me know.

Hi Julian,

The only options I have are: Radius, Absolute, Delta start to center, Delta center to start, Unsigned incremental, Signed radius. Which one would be?
Thanks

It depends on your cnc machine needs, Delta start to center will output i and j which represent the signed distances from the start point of your arc to the centre. This is the option i use for my acromatic control. Any probs let me know

Change the .pst file as Bmackinnon has suggested.
The control definition changes the arc type. Delta, Absolute, Etc.
The .pst file changes the IJK or R arc output.

Thank you guys for your help. I found Julian's way simpler, and it worked.
