<div class="markdown_content"><p>Hi ByCNC,</p> <p>here is the automatic translation of your comment, as I do not understand turkish:</p> <p>&lt;&lt;&lt;<br/> Hello Georg,</p> <p>You've helped me before and I'm grateful for that. I have a new problem maybe you can take it? Currently there is excessive vibration on the X-Y axes when doing radius operation with CNC Interpolation. The value of "bdAngleTol" to smooth the radius. Even if I manage to smooth the path, this path reveals excessive pulsating motion. Can you have an idea for this?</p> <p>Thank you.</p> <blockquote> <blockquote> <blockquote></blockquote> </blockquote> </blockquote> <p>Are you using SMC_ToolRadiusCorr? Is this causing the vibration? Are you using SMC_SmoothPath for smoothing the path?</p> <p>Best regards,</p> <p>Georg</p></div>

<div class="markdown_content"><p>Merhaba Georg,</p> <p>Daha önce bana yardıma dokunmuştum bunun için minnettarım. Yeni bir sorunum var belki alabilirsin? Şu anda CNC Interpolasyon ile yarıçap işlemi yapılırken X-Y eksenlerinde aşırı titreşim oluyor. Yarıçap yumuştamak için "bdAngleTol" değeri değeri. Yolu yumuşatmayı başarsam da bu yol aşırı vuruşlu hareketi ortaya çıkarıyor. Bunun için fikrin olabilir mi ?</p> <p>teşekkürler.</p></div>

<div class="markdown_content"><p>Hi,</p> <p>no, it is not possible to change the link twist for SMC_Trafo(F)_ArticulatedRobot_6DOF.</p> <p>If the robotics kinematics Kin_ArticulatedRobot_6DOF uses the convention for link twist you expect, you could wrap it into two FBs with the same inputs/outputs as SMC_Trafo(F)_ArticulatedRobot_6DOF and use these FBs with your CNC application.</p> <p>Georg</p></div>

<div class="markdown_content"><p>Thanks George<br/> the thing is when i was comparing Forward Kinematics Values from 'SMC_TrafoF_ArticulatedRobot_6DOF' of Codesys &amp; Roboanalyzer outputs are not matching, because link twist value in column 1 is actually -90 as said in 'SMC_Trafo_ArticulatedRobot_6DOF' documentation, but in axis group it is shown as +90 which is what i require but not present in program like</p> <p>So is there any way to change column values of link twist &amp; joint offset</p></div>

<div class="markdown_content"><p>Hi intvenkat,</p> <p>the parameters of the robotics kinematics "Kin_ArticulatedRobot_6DOF" are explained here, with pictures:</p> <p><a href="https://content.helpme-codesys.com/en/libs/SM3_Transformation/Current/SM3_Transformation/Function-Blocks/Standalone-Kinematics/Articulated-Robots/6AxisArticulated/Kin_ArticulatedRobot_6DOF.html" rel="nofollow">https://content.helpme-codesys.com/en/libs/SM3_Transformation/Current/SM3_Transformation/Function-Blocks/Standalone-Kinematics/Articulated-Robots/6AxisArticulated/Kin_ArticulatedRobot_6DOF.html</a></p> <p>Does this help, or are you looking for further information about the CNC function block "SMC_TrafoF_ArticulatedRobot_6DOF"?</p> <p>Best regards,</p> <p>Georg</p></div>

<div class="markdown_content"><p>Hello Everyone, </p> <p>Is there any documentation to understand 6DOF articulated Kinematics blocks in Axis-group, In the go to Definition section it is limited</p> <p>For using FK block 'SMC_TrafoF_ArticulatedRobot_6DOF' I have to create separate variable for DH parameters</p> <p>Direct axis group parameters I am not able to link &amp; the parameters here are less when compared to axis group</p> <p>The output values I am getting when using RoboAnalyzer software &amp; codesys are different<br/> How to approach this kinematics part of codesys</p></div>
