http://www.zwsoft.com/forum/viewthread.php?tid=968 The project adds helical ramping for 2X spiralcut, zigzag, contour and top facing. One new option of Helical is added to the field of "Plunge Type". A new field of "Plunge Radius %" under the tab of"Lead and Link Parameters" is also added to define the maximum radius of helical ramping as the percentage of the tool radius. To access helical ramping, select "Helical" as the plunge type and also make sure that both "Plunge Angle" and "Plunge Radius %" are defined. <img src="http://zw3d.zwcad.org/ftproot/vxfiles/Private/forumfiles/2x_helical.png"> tony 2011-12-26 01:56:29 http://www.zwsoft.com/forum/viewthread.php?tid=968&pid=14318 Its a great thing that A new field of "Plunge Radius %" under the tab of"Lead and Link Parameters" is also added to define the maximum radius of helical ramping as the percentage of the tool radius. <a href="http://www.maurymw.com/MW_RF/Time-Domain_X-Parameter.php"><b>x-parameters</b></a> emmas 2012-02-13 16:45:09
