As a consequence, the resulting motion along trim plane containment that cuts through this layer of remaining material until the tool touches the part profile gets relatively short and in general perpendicular to the subsequent finishing motions. Even worse, the corresponding engage motion may become tangent to this short initial cutting motion instead of being tangent to the part profile.</p>

If  <a class="links" href="javascript:void(0)" onclick="top.openFile('mfgturning/06topic_27.html');return(false);">trim point containment</a> has been chosen, this option ensures that the engage motion (displayed in yellow color in this example) directly contacts the part surface (or the part surface plus stock if specified), i.e., directly leads into the trim point.
