<div class="markdown_content"><p>Hello Forum users,</p> <p>I want to make the following axis configuration:</p> <p><img src="./attachment/attachment.png" width="50%"/></p> <p>The square is a rectangular (with rounded corners) workpiece that rotates around a rotary axis. <br/> Perpendicular to that axis is a linear axis. When the rotary axis rotates, the linear axis should follow the workpiece on toolpath. </p> <p>What would be the best way to approach this?</p> <p>Would it be the best to use a linear XY axis system and somehow convert one of the linear axis to a rotary movement (in some cnc's this is a Gcode function)</p> <p>Or is it possible to always let the linear axis follow the rotary axis in this profile? The dimensions of the workpiece vary so in this case the profile has to be variable.</p> <p>I have looked to the robotics polar kinematics (kin_polar) but unfortunatly these kinematics don't support CP movements...</p> <p>Thanks!</p> <p>Benny</p></div>
