Raghav Posted June 15, 2011 Share Posted June 15, 2011 Dear All, I'm facing a major problem in my Turbo PMAC system in which while using G02/03 command elliptical toolpath is achieved instead of circular. I tried to find the cause of the problem but in vain. Can anyone let me know what could be wrong for this error to occur. Thanks. Link to comment Share on other sites More sharing options...
Sina.Sattari Posted June 15, 2011 Share Posted June 15, 2011 Raghav, Please check the following as all of these can cause a circular path to turn into an elliptical path: - make sure the normal you are defining matches the plane your tool is expected to move in a circular path. - make sure you don't have any unknown rotation transformation happening. - make sure your scale factors for axis definitions are correct.

Omron Forums Support Posted June 17, 2011 Share Posted June 17, 2011 Make sure your segmentation time (Isx13, units of ms) is greater than zero and properly configured per page 156 of the Turbo SRM for the amount of error your cuts can tolerate. You may also consider using lookahead (Isx20) and maximum circle acceleration (Isx78), both of which are described in the Turbo SRM. Link to comment Share on other sites More sharing options...
Raghav Posted June 18, 2011 Author Share Posted June 18, 2011 The problem is resolved now. Since one of the encoder we had was faulty we changed it and never checked for the resolution of it. Since there was a difference in the resolution, the motion weren't synchronized. Thanks. Link to comment Share on other sites More sharing options...
