      <description>&lt;P&gt;Hi. Is there a way to create multistart threading cycle with FeatureCam with Lathe machine? I want to create knurling surface with single point thread tool. Was searching some solution on internet but.... We have HAAS ST30 (Fanuc) in our workshop. I guess that G32 option would be the answer to our problem. Maybe G76 would do the job but than again it would require one program to go from right to left and second program to go from left to right in Z axis, with same X,F,K,D values to create knurling surface. With G32 i guess will go only with changes in Z values +/- . Basically, is there a way to program this with FeatureCam, with multiple starts of threading cycle (probably more than 40 starts ) ? Challenge is to use the single point thread tool, not knurling tool. Thank you.&lt;/P&gt;</description>

      <description>&lt;P&gt;I use this to get multi start threads.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;&lt;EM&gt;Start threads&lt;/EM&gt;&lt;SPAN&gt;&amp;nbsp;— If set to&amp;nbsp;&lt;/SPAN&gt;&lt;SPAN class=""&gt;1&lt;/SPAN&gt;&lt;SPAN&gt;, a single thread is created. If set to&amp;nbsp;&lt;/SPAN&gt;&lt;SPAN class=""&gt;2&lt;/SPAN&gt;&lt;SPAN&gt;&amp;nbsp;or&amp;nbsp;&lt;/SPAN&gt;&lt;SPAN class=""&gt;3&lt;/SPAN&gt;&lt;SPAN&gt;, multiple start threads are created. The number of threads per inch (or per mm) for each thread is divided by the number of threads. For example, if you create a thread with 10 threads per inch with 2 start threads, then each thread is 5 threads per inch 180&lt;/SPAN&gt;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;&lt;SPAN&gt;&amp;nbsp;apart.&lt;/SPAN&gt;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;&lt;span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="2023-11-15_09-32-47.png" style="width: 790px;"&gt;&lt;img src="https://forums.autodesk.com/t5/image/serverpage/image-id/1293368iBAEABFF9CDB0B649/image-size/large?v=v2&amp;amp;px=999" role="button" title="2023-11-15_09-32-47.png" alt="2023-11-15_09-32-47.png" /&gt;&lt;/span&gt;&lt;/P&gt;</description>
