Explore the production techniques behind cavity dimensions and the smallest tread details.
Scanning digitises the sample surface. Reference planes align this capture with the technical drawing.
Toe, waist and heel sections are examined separately. Wear marks in the point cloud are distinguished from design features before checking left-right correspondence.
In stereolithography, light selectively cures a photosensitive resin.
Build orientation influences the direction of layer marks and support placement determines contact marks. Visible tread and fine edges guide support positioning.
Flexible silicone captures relief in negative. Plaster forms a more rigid copy from that impression.
Air trapped at the bottom of a deep groove can interrupt surface reproduction. The release direction is planned to protect delicate relief during removal.
Casting considers both metal flow into the cavity and the order in which sections solidify.
Feed paths and changes in section affect narrow-zone filling and cooling of thicker regions. Machining allowance is left on faces that will be cut later.
The CAM toolpath determines the cutter’s approach direction and the spacing between passes.
Fixturing and datum setting locate holes and closure faces on the casting. In narrow internal corners the achievable radius depends on cutter diameter.
Hand dressing and selective polishing remove machining marks while preserving tread definition.
Side lighting reveals fine marks and transitions. A textured face and a plain edge can be finished with different tools to avoid rounding the relief.
