Dear all:

Thanks for your valuable helps

This is CL data for milling just a milling of square block of 100.0 x 100.00 x5.0 (I give depth of cut 5.0)

I would like to know

1.what is the meaning of

 

[orac]

I think nr.1 $$->CSYS gives an indication of the orientation of the coordinate system used to program the part with respect to the orientation default coordinate system of the machine. This way it can easily be determined if the fixture of the part is rotated or similar.


Nr. 2 is used to determine whether the circular movement is clockwise or not and in which plane (XY, XZ, YZ) it is done.


If you have 0,0,1 the circular movement is within the xy plane and the direction is from the x to the y axis so it is CCLW.


If you have 0,0,-1 the circular movement is within the XY plane and the direction is fomr the y to the x axis so it is CLW.


Hopefully this can be confirmed or corrected by someone who is more knowledgeable thanI'm.


Best regards,

Hi John,


Correct on both counts.


I would like to add that $$-> CSYS is commented out (note that $$ upfront), so it does not do anything unless you do special processing in your post to see it.


It is a matrix describing the Sequence coordinate system in the frame of the machine coordinate syetem. A good usage for it is for 5-axis machines that require a frame rotation/translation (like G65 for example), and you can use it in the post to figure out frame matrix.

Hi Charles,


You intrigued me with the comment about "special processing in your post." In Gpost how do I get the post to read the $$->comment lines?

Hi Bob,


The easiest is to capturethe $$-> CSYSas CAMERA. It is converted to CAMERA command in GPost.


You can also capture REMARK for all comments, but for $$-> CSYSyou will have a harder time parsing the text that way. All $$ commenst become REMARK command in GPost.

Dear Mr.Chf65

Highly appreciated if you could explain a bit more..

Still fresh to GPOST.

Hi Leow,


You make a CIMFIL on CAMERA, and then extract the values using
POSTF(7,4), POSTF(7,5), etc.


You do not need to worry about this if new to post writing. You normally do not need it, unless you have a good reason for it.
