Surface finish is managed by controlling feed rate, cutting speed, and tooling geometry. Most systems include a variable-speed spindle and servo-driven motion, allowing smooth cutting across metals, polymers, or composites.

For fine surface preparation, users can apply multi-step passes or use polishing and sanding attachments. The TensileSoft™ interface and compatible systems provide precise control of finishing parameters to achieve the required surface quality for accurate mechanical testing. In laboratories, a visual or profilometer inspection is typically performed to confirm that the finish meets the testing standard’s requirements.
